4875enhancements: Particle systems are no longer limited to rendering with

4877subclasses, which can be implemented in plugins and added at runtime.

6733   
6734   
6735    <p style="margin-bottom: 0cm;">Binary mesh format
6736enhanced. Previously the binary mesh format did not support all the
6737flexibility you could attain when you built meshes programmatically.
6738This has been addressed, and the mesh can now store arbitrary vertex
6739buffer formats, precomputed edge lists (for stencil shadows), and
6740tangent-space vectors (for normal mapping). You are strongly adviced to
6741use the OgreMeshUpgrade tool on all your meshes to uprade them to the
6742latest version, and choose 'y' when asked if you want to reorganise
6743your vertex buffers. The 'automatic' option is the quickest way to get
6744your meshes up to date, and you may find them slightly faster to render
6745
6746as a result. <br>
6747
6748
6749
6750
6751Bear in mind that the .mesh size will increase because edge lists are
6752precomputed and stored by default - if you don't intend to use stencil
6753shadows then you can disable this with the '-e' parameter.</p>

6765   
6766   
6767    <p style="margin-bottom: 0cm;">OpenGL Shading Language
6768(GLSL) support. This means Ogre now supports programmable shaders
6769written in Cg, HLSL, GLSL and all variants of assembler (DirectX and

6784    <p style="margin-bottom: 0cm;">Explicit Radian, Degree
6785and AngleUnit classes. To resolve ambiguity as to which angle unit is
6786being used, all methods which take an angle now take a Radian class.
6787You can pass Degree instances to this too and get automatic
6788degree-to-radian conversion. You can also use the AngleUnit class which
6789defaults to the current angle units (see Math). Note that conversions
6790are inlined and are thus very cheap; although if you want to avoid them
6791entirely, use Radian. This is an interface breaking change, so you will
6792need to update your code to use Radian(radianValue) or
6793Degree(degreeValue) where you are using basic types to store angles.</p>

6808enhancements. Automatic reflections using dynamic planes are now simple
6809to create using MovablePlane, and 'custom near clip planes' (oblique
6810depth projection) are available to allow you to clip reflected geometry
6811to an arbitrary plane without requiring additional hardware support

7706attached to a single edge, and reverts to not welding vertices across
7707vertex sets. This allow it to deal with multiple capped submeshes with
7708their own geometry (which are manifold in themselves) even if they
7709touch at the boundaries. At the same time it still deals with the case
7710where a model is only manifold when all submeshes are combined (it
7711tries to find this case first).</p>

7878and render sequence when shadows are enabled, since supporting several
7879types of shadows has required these processes to be significantly
7880enhanced and decomposed into multiple parts (which should lend
7881themselves to customisation in your SMs if you need them). In
7882particular, note that the signature of
7883SceneManager::_findVisibleObjects has changed so if you override this
7884you will need to alter yours too - the compiler will not tell you about

8023hook up external effects on the bones on particular instances of that
8024skeleton (in entities); applications such as manually controlling bones
8025or ragdoll simulations benefit from these enhancements. </p>

8713lights in the scene, and OGRE will pick and use the 'n' closest lights
8714('n' is configurable per pass in the material scripts) which are within
8715their attenuation range when rendering an object. This makes light
8716management much more practical, especially when using vertex and
8717fragment programs. As mentioned above, passes can even be configured to
8718iterate using the 'n' nearest lights. </p>

8845and improves loading times as well as making compressed texture support
8846feasible. The .mesh format will be converted on the fly automatically,
8847but you should use OgreMeshUpgrade to fix it permanently </p>

9709   
9710   
9711   
9712    <p style="margin-bottom: 0cm;">SceneQuery introduced;
9713a generic way to query the SceneManager database of objects and world
9714geometry in a way which is optimised per scene management technique but
9715transparent for the client application. Currently only
9716IntersectionSceneQuery is implemented but RaySceneQuery,
9717SphereSceneQuery and others will soon be available too </p>

9731    <p style="margin-bottom: 0cm;">ReferenceApplication
9732introduced; this is a new library which sits on top of the main OGRE
9733library in order to provide a reference implementation of combining
9734OGRE with other libraries for use in a full application. Currently
9735combines OGRE and ODE to provide an easy to use collision and realistic
9736physics system, utilising the new SceneQuery functions for generic
9737collision detection. Object to object collision is currently supported,
9738together this object to world collision for the BspSceneManager (ie
9739collision against Quake3 levels), see the BspCollision demo for an
9740example. Per-object friction, bounciness and mass parameters are all
9741definable, also most of the ODE joint types ie ball, hinge, hinge2,
9742universal. World collision for the terrain managers will be added
9743shortly. </p>

9758enhancements to the GLRenderSystem, including an extension manager,
9759separation of window creation etc into a GLSupport class (to enable
9760platform specific window management). Win32GLSupport added so Win32 no

11386will not be developed further due to it's relatively high CPU overhead,

11858I'm not going to implement this for now, I've proved the point I
11859wanted to prove which is that Ogre can handle this type of scene
11860well. It's just a few Q3-specific details which are missing which is

11894<p align="left">Quake3 shader script conversion is going
11895well, Ogre
11896loads in the .shader files and converts them to Material objects as
11897required, meaning that you can now see flames, shafts of light, TV
11898screens etc inside Ogre. Animated textures are being loaded but not
11899animated yet - I'm going to try and get animation working within a
11900nice generic OO controller framework if I can rather than bash out a
11901single-use approach.</p>

11904
11905
11906<p align="left">One thing I've noticed now the sky is
11907being displayed
11908is there are 'sparklies' around the curved surfaces visible mostly
11909when there is a light-coloured sky. Damn. It appears the points
11910generated from the bezier patches don't quite match up with the
11911surrounding static geometry, meaning there are small gaps. This is a
11912TODO.</p>

11917<p align="left">I still need to fix the odd crash point
11918and a few

11920a bit of work since Quake3 bases them on camera position -&gt;
11921vertex
11922rather than camera eye vector -&gt; normal, which means they look
11923wrong. I should alos render the 'models' in the level i.e. geometry
11924that doesn't have lightmaps like gargoyles.</p>

11946there is now an Examples folder with multiple projects under this
11947which demo each effect. I have also created an object-oriented
11948framework for the examples too, meaning they are now a lot better
11949structured and hopefully better to understand.</p>

11954<p align="left">I also intend to release some binary demos
11955soon so
11956people can quickly see what the engine is capable of without having
11957to build from the source. The good news this week is that I just did
11958a Release build of the Quake3 level renderer, and it runs at a very
11959sweet 170fps in windowed mode on my Athlon 1Ghz and GeForce 2. In
11960fullscreen mode at 1024x768 at 32-bit colour it still manages between
1196150 and 80 fps. I'm very pleased indeed. I would like to tidy up some
11962of the missing textures before I do a binary release so I'll be
11963sorting out the skybox support and other texture effects first.</p>

11998RenderSystem. This ensures that rendering state changes are minimised
11999and that custom settings are reset only when required. This has
12000improved the framerate across the board by about 50%. A further
12001optimisation which is still to be made is ordering the materials in
12002the render sequence to minimise the render state changes still
12003further, e.g. scheduling 2 materials that have the same layer 0

12065<p>Modified the material blending routines to make it more
12066reliable
12067to fall back on multipass rendering whilst preserving all the correct
12068effects. To do this I had to simplify the basic multitexture blending
12069operations which automatically fall back to multipass, and require
12070that the application explicitly specifies a fallback blend multipass
12071operation if it chooses to use the more complex blending modes which
12072are only available under multitexture hardware. I hope by doing this
12073I keep it simple for most cases (people normally use jusy ADD,
12074MODULATE, REPLACE or ALPHABLEND anyway) whilst still allowing
12075complete flexibility for those who like to tinker with the obscure
12076modes.</p>

12100
12101<p>I keep getting distracted from my Quake3 level work but I am
12102progressing - the reason why I switched to this subject is that I
12103realised my fallback technique to multipass rendering when not enough
12104multitexturing hardware was available was not correct, and in order
12105to be able to fix it I needed these new blending options. I'm now
12106wondering whether to fix the multipass fallback now I have the tools
12107or to leave it until later. Right now, if you use more texture layers
12108than the hardware supports in a single pass, things won't look right.
12109I'll get to it.</p>

12118
12119<p>Ok, remember the problem from 16 September re texture
12120coordinates
12121and confusion over whether (0,0) was the top or bottom left corner of
12122the texture? Well it turns out that once again Direct3D is the odd
12123one out, and 3DS is actually using the more common convention, i.e.
12124(0,0) is the <i>bottom</i> left corner. I have therefore
12125changed the
121263ds2oof routine <i>back</i> to how it was before (using
121273DS UV
12128corrdinates directly) and am flipping the texture itself in the
12129Y-axis when loading it in the Direct3D texture implementation to
12130compensate (D3DTexture.cpp). I should have checked more thoroughly
12131before changing things to be in line with D3D, I should have known it
12132would probably be the odd one.</p>
12133
12134
12135
12136
12137<p>I've done this because I want Ogre to follow industry
12138standards
12139(e.g. right-handed coordinates, anticlockwise vertex winding) rather
12140than Direct3D's viewpoint which is usually the opposite, even though
12141it's Direct3D I'm working on at the moment. I do this because it's
12142what everybody will be used to when they come from maths texts or
12143modelling tools, and is the same as the OpenGL approach (so the
12144OpenGL port should be easier than Direct3D). I just compensate inside
12145my Direct3D-specific classes (e.g. by flipping the Z axis, changing
12146the culling mode, or flipping the texture as above).</p>

12162
12163<p>I have also fixed a couple more bugs: the ColourValue class
12164was
12165implementing colours a little too bright and wrapped around to black
12166when pure white was specified. This has been fixed. In addition, the
12167mipmap generation was not generating enough mipmaps under Direct3D
12168because D3DX ignores requests for the number of mipmaps and generates
12169as many as required to reduce to a 1x1 texture. This caused smaller
12170mipmaps to be black and thus textures would wink out at long
12171distances. This has been fixed.</p>

12181<p>Slow going due to moving house. However, fixed a problem with
12182texture coordinates as converted from 3DS using 3ds2oof - I just
12183realised that 3DS uses UV coordinates where V=0.0 is at the <i>bottom</i>
12184of the texture map, instead of the top as with everything else! That
12185explains the strange textures on some models. Fixed 3ds2oof to make
12186V=(1.0 - V) during the conversion. Reconvert your models!</p>

12196<p>Ogre now supports loading of resources from more flexible
12197locations, including compressed archives (.zip and Quake3 .pk3
12198files). You can specify a list of search paths and archives which are
12199either general across the whole of Ogre or specific to a resource
12200type (e.g. textures, meshes).</p>
12201
12202
12203
12204
12205<p>I've also added support for loading TGA images as well, since
12206Quake3 maps use them in places. </p>
12207
12208
12209
12210
12211<p>I have also dropped support for BMP files. This is because I
12212have
12213had to implement memory-based versions of the image decoders to
12214support loading from archives, and to be frank I couldn't be bothered
12215to implement one for BMP since it's a naff format in my opinion and
12216tied to the Windows platform anyway. Ogre supports JPEG, PNG and TGA
12217which should be plenty of flexibility. Personally I think when you've
12218got PNG (for lossless) and JPEG (for lossy), you don't need anything
12219else.</p>

12229<p>Texture blending is now in and working! The new TestApp

12233to show what effects different parameters have.</p>

12241materials and entities that I'd like to look at but I'd really like
12242to get started on Q3A bsp files now. I also wanted to work on
12243animation, both within models (skeletal animation &amp; bones) and
12244for paths of objects (bezier curves &amp; bsplines), but I just
12245don't
12246have time to do everything I want to! Q3A files first.</p>

12261<p>The Camera class now allows a SceneNode to override it's

12265
12266
12267
12268
12269<p>Started implementing the texture blending operations - the
12270interface is complete, I'm now moving onto the Direct3D
12271implementation. For the moment I'm not worrying about minimising the
12272number of times that changes to blending parameters are made during a
12273frame - I'm still concentrating on minimising the texture changes,
12274which is the main overhead anyway. More optimisation will likely come
12275along with new SceneManager subclasses.</p>

12283
12284
12285<p>The Camera class now uses quaternions too. Camera rotation is
12286a
12287lot more concise now (instead of storing &amp; trying to update 3
12288vectors I just have a single quaternion) and is more predictable and
12289hopefully more flexible for the future.&nbsp;</p>
12290
12291
12292
12293
12294<p>You can attach a Camera to a SceneNode (this is meant for use
12295in
12296having cameras tracking other objects in the world) but I have yet to
12297implement this - I intend now that they're both on the same basis
12298that if you choose to attach a camera to a scene node then the
12299SceneNode overrides the camera's own position and direction, and
12300maybe even that they update each other (so telling a camera to look
12301somewhere would update the orientation of it's SceneNode too).</p>

12309
12310
12311<p>Updated SceneNode class to use quaternions internally for all
12312orientations / rotations. This should both be faster and give me more
12313flexibility for the future. Also added a lot more manipulation
12314routines the SceneNode class which were sorely lacking before if you
12315wanted to move stuff around. The Camera class still uses matrices
12316internally but I intend to change that so that a Camera depends on
12317the SceneNode it is attached to for positioning rather than doing it
12318itself. To this end I will need to add extra features to the
12319SceneNode class to replicate functions like lookAt(), which is ok
12320since this will be handy for pointing other objects at each other
12321too.</p>

12332vertex
12333normals based on smooth groups rather than just averaging based on
12334the faces which use the vertex. This removes artefacts along model
12335'seams' e.g. the point where a texture wraps around on the model.</p>
12336
12337

12352<p>Python now has full access to the engine, and it's working

12354I've also enabled callbacks into Python from the engine, so you can
12355register a Python class as a listener for frame update events so C++
12356calls Python every frame. Nice.</p>
12357
12358
12359
12360
12361<p>Future Python developments include an embedded version of
12362Python
12363in Ogre so you can build a compiled application which still used
12364interpreted scripts for some things - this will be useful for level
12365scripting etc where the script can be kept in the level data. For now
12366though I'm going back to developing the core engine features .</p>

12380issues to iron out - I had to extend the compiler heap limit to get
12381it to compile so far since the heavy usage of templates puts a great
12382strain on the compiler memory usage. In a few days I should be in a
12383position to do all my engine testing through Python as well as

12395represent

12397User applications now extend FrameListener and register their
12398interest in receiving frame events - this is based on the Java model
12399of event listening. Note that a boon of this method is that Boost
12400Python allows you to extend existing C++ classes so this provides a
12401perfect mechanism to have C++ call Python scripts when events occur. </p>

12418<p align="left">Changed from using SWIG to Boost Python
12419for Python
12420script integration. I changed because Boost Python supports C++
12421features much beter (including catching C++ exceptions and turning
12422them into Python exceptions, support for namespaces and overloaded
12423operators), it integrates better with my build cycle (doesn't require
12424a separate generate from interface files and can be built directly
12425into the library), and is more up-to-date with the latest Python
12426libraries. I was finding that SWIG's emphasis on pure C as opposed to
12427C++ was getting in the way, and Boost has definitely addressed this.</p>

12511<p align="left">Implemented Mesh, SubMesh and MeshManager
12512classes for
12513loading Ogre Object Format files (converted from .3ds using the Ogre
125143ds2oof tool). Decided to allow the original 3ds mesh to be broken
12515down into chunks specific per material or grouped as a whole
12516depending on requirements. The 3ds2oof utility makes a goos guess as
12517to what is best, based on the percentage of the vertices each SubMesh
12518uses out of the whole model - the lower the percentage the greater
12519chance it will have a dedicated vertex list rather than sharing the
12520whole since that saves sending unnecessary vertices to the pipeline.
12521However this can be customised with parameters since you may want to
12522use vertex buffers where it's more efficient to store 1 buffer even
12523if you only use parts of it.</p>

12592<p align="left">Changed the default mechanism for
12593supplying vertex
12594components (position, normals, texture coords, colours) to the
12595RenderOperation class. They were previously assumed to be part of the
12596same buffer with flags indicating which were present. However this
12597was too restrictive and prevented you using entirely separate memory
12598areas for different components, and adding extra components to
12599vertices on the fly. </p>
12600
12601
12602
12603
12604<p align="left">Instead the RenderOperation class now
12605takes pointers
12606for each component, and a 'span' value determines the gap between
12607each value. This allows you to use separate buffers if you like, but
12608also use a combined buffer if that suits you (by using the 'span'
12609value to skip over values in between).</p>

12619<p align="left">Implemented a 3DStudio conversion tool
12620that works
12621directly from the .3DS files rather than from ASCII exports (as
12622previously) or from a MAX plugin as some others do, which requires a
126233DS license. I based my code on an existing open source routine but I
12624have exteded it since it had a few shortcomings. The tool is called
12625'3ds2oof' because it converts 3DS files to a proprietary format, .OOF
12626(Ogre Object File). This is because it's more efficient for me to do
12627extra processing at conversion time like calculating bounding boxes,
12628splitting vertex buffers, strippifying etc (not that I'm doing all
12629this yet, but I <i>can</i>) rather than at load time as I
12630would have
12631to do if I loaded direct from 3DS inside Ogre.</p>

12642interface to
12643the DirectX rendering pipeline in the new Ogre structure, under the
12644D3DRenderSystem class. Rendering requests are now packaged up in the
12645RenderOperation class, giving me more flexibility on how rendering
12646requests are submitted and handled. Now all the support classes (mesh
12647loading, scene management) are needed.</p>

12657<p align="left">I've been picking apart the platform
12658dependencies in
12659Ogre so it'll be more portable. I'm also making it flexible enough to
12660handle any number of rendering windows and viewports within thse
12661windows, and also giving you the choice of an automatic rendering
12662loop (max frame rate) and a render-on-demand interface much like you
12663would need for an application like a modelling tool where you want to
12664free up cycles when things don't move and frae rate isn't the most
12665important thing.</p>

12672OgreWin32Platform modules, with functionality broken down into
12673RenderTarget, RenderWindow and Win32RenderWindow classes. Other
12674platforms can be implemented later, just replacing the
12675Win32RenderWindow maybe with XRenderWindow or MacRenderWindow.</p>
