|
---|
| 30 |
|
---|
| 31 | Instead of rendering to the frame buffer this Technique renders into two render targets at the same time.
|
---|
| 32 | The firs render target will be used as it were an ordinary backbuffer.
|
---|
| 33 | The second rendertarget will be used to simulate heat shimmering (offset values will be written to it).
|
---|
| 34 | The shimmering effect will be achieved with post processing: combining the backbuffer with the first render target using the second render target as uv offset.
|
---|
| 35 | Just like the spherical billboard techniqeue, this thechnique requires a depth image taken from main camera's viewpoint.
