| 34 | @remarks
|

| 35 | Note that the syntax of D3D9 HLSL is identical to nVidia's Cg language, therefore
|
---|
| 36 | unless you know you will only ever be deploying on Direct3D, or you have some specific
|
---|
| 37 | reason for not wanting to use the Cg plugin, I suggest you use Cg instead since that
|

| 38 | can produce programs for OpenGL too.
