Function Documentation

AiShaderEvaluate()

AI_API void AiShaderEvaluate	(	AtNode *	node,
		AtShaderGlobals *	sg
	)

Evaluate a shader.

Use this to evaluate a shader (or shader network) at the given shading context.

Parameters

	node	the shader node that will be evaluated, must be non-NULL
[in,out]	sg	the non-NULL shader globals context for this shader evaluation, with the return value in sg->out
