| public virtual double RED::ISoftShaderContext::GetGlossyAngle | ( | ) const = 0 |
Returns:
the glossiness angle.
| public virtual double RED::ISoftShaderContext::GetGlossyAngleAniso | ( | ) const = 0 |
Returns:
the anisotropic glossiness angle.
| public virtual int RED::ISoftShaderContext::GetGlossySamplesCount | ( | ) const = 0 |
Returns:
The number of glossiness samples to fire.

| const RED::ISoftRayContext & | iRayContext, | ||
| const RED::ISoftRenderingContext & | iRenderContext | ||
| ) | const = 0 |
Gets a matrix parameter streamed as 4 program locals.
Parameters:
| ioMatrix: | Receive the matrix components. |
| iBindPos: | The matrix binding position (first row out of 4). |
| iRayContext: | The actual ray context. |
| iRenderContext: | The actual rendering context. |
| public virtual void RED::ISoftShaderContext::GetProgramLocal | ( | double | oParameter[4], |
| int | iBindPos, | ||
| const RED::ISoftRayContext & | iRayContext, | ||
| const RED::ISoftRenderingContext & | iRenderContext | ||
| ) | const = 0 |
Gets a program parameter.
Parameters:
| oParameter: | Reference to the returned program local value. |
| iBindPos: | Binding position of the parameter. |
| iRayContext: | The actual ray context. |
| iRenderContext: | The actual rendering context. |
| public virtual RenderCode & RED::ISoftShaderContext::GetRenderCode | ( | ) = 0 |
Gets the shader binding specification.
Returns:
The address of the RED::RenderCode to use for this shader.
| public virtual const RenderCode & RED::ISoftShaderContext::GetRenderCode | ( | ) const = 0 |
| public virtual const int * RED::ISoftShaderContext::GetStateVector | ( | ) const = 0 |
Gets the state vector.
The state vector is unused if we are used for a render shader.
Returns:
The statevector in this shader context.
| public virtual RED::Object * RED::ISoftShaderContext::GetTexture | ( | int | iBindPos, |
| const RED::ISoftRayContext & | iRayContext, | ||
| const RED::ISoftRenderingContext & | iRenderContext | ||
| ) | const = 0 |
Gets a shader texture.
Parameters:
| iBindPos: | Binding position of the texture. |
| iRayContext: | The actual ray context. |
| iRenderContext: | The actual rendering context. |
Returns:
The texture address.
| public virtual void RED::ISoftShaderContext::MatrixLocalMultiply4 | ( | double | oVector[4], |
| int | iBindPos, | ||
| double | iVector[4], | ||
| const RED::ISoftRayContext & | iRayContext, | ||
| const RED::ISoftRenderingContext & | iRenderContext | ||
| ) | const = 0 |
Homogeneous product of a vector by a local matrix.
Parameters:
| oVector: | Resulting transformed vector (can be the same as 'iVector'). |
| iBindPos: | Binding position of the first matrix vector. If 'iBindPos' is negative, 'oVector' is returned equal to 'iVector'. |
| iVector: | Input vector. |
| iRayContext: | The actual ray context. |
| iRenderContext: | The actual rendering context. |
