RayGIDiffuseShader
Functions
Detailed Description
-
class RayGIDiffuseShader : public RED::RenderShader
Built-in Global Illumination shader for diffuse color and normal calculations.
@related Using Built-in Render Shaders, class RED::IMaterial, class RED::RenderShader, class RED::StateShader, class RED::RenderCode
This shader works with any built-in lighting shader (RED::RenderShaderPhong, RED::RenderShaderLambert, …). It uses the same set of parameters used to define diffusion and interpolated normal parameters in the lighting shader. Values produced by this shader are used for global illumination calculations.
This shader is intended for use in the RED::MTL_RAYTRACE rendering pass.
This shader has 4 configurations:
See the REDRayGIDiffuseShader.h file documentation for the list of all #define statements used to name all parameters of this shader.

Public Static Functions
-
static RED_RC LoadProgram(RED::String &oString, const RED::ShaderProgramID &iID)
Loads a shader program.
Generates a shader program that corresponds to the specified iID.
- Parameters
oString – The created program string.
iID – The shader program unique ID.
- Returns
RED_OK if the shader could be loaded,
RED_ALLOC_FAILURE if an allocation has failed,
RED_FAIL otherwise.
-
static RED_RC EvaluateFromInputParameters(RED::RenderShader *ioShader, RED::Object *iResMgr)
Evaluate a shader from its input parameters.
- Parameters
ioShader – Shader to redefine using its own input parameters.
iResMgr – The cluster’s resource manager.
- Returns
RED_OK if the operation has succeeded,
RED_BAD_PARAM if iShader was not valid,
RED_BAD_PARAM if an invalid parameter was found during the evaluation,
RED_ALLOC_FAILURE if a memory allocation has failed,
Other RED_RC related to shader creation can be returned.
