Validation (Direct3D 9)

  • Article

Validation is performed during the effect compile. To validate the current technique, specify NULL as the technique handle to be validated.

Validation will fail for any of the following:

  • If the specified technique handle does not exist.
  • If the application of any state in any pass of the technique fails.
  • If device validation fails after the application of all the states in any pass of the technique.
  • If the PIXELSHADER or VERTEXSHADER effect states are assigned invalid shaders in any pass of the technique.
  • If the device caps do not support cube mapping, and a TEXTURE effect state is assigned a value of type textureCUBE in any pass of the technique.
  • If the device caps do not support volume mapping and a TEXTURE effect state is assigned a value of type texture3D in any pass of the technique.
