Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkRenderPass.

Reimplemented in vtkSobelGradientMagnitudePass, vtkValuePass, vtkShadowMapPass, vtkShadowMapBakerPass, vtkToneMappingPass, vtkPointFillPass, vtkSimpleMotionBlurPass, vtkOrderIndependentTranslucentPass, and vtkPanoramicProjectionPass.

virtual bool vtkOpenGLRenderPass::PreReplaceShaderValues ( std::string &  vertexShader,
std::string &  geometryShader,
std::string &  fragmentShader,
vtkAbstractMapper mapper,
vtkProp prop 
)
virtual

Use vtkShaderProgram::Substitute to replace //VTK::XXX:YYY declarations in the shader sources.

Gets called before other mapper shader replacements Return false on error.

Reimplemented in vtkShadowMapBakerPass, vtkShadowMapPass, and vtkDualDepthPeelingPass.

virtual bool vtkOpenGLRenderPass::PostReplaceShaderValues ( std::string &  vertexShader,
std::string &  geometryShader,
std::string &  fragmentShader,
vtkAbstractMapper mapper,
vtkProp prop 
)
virtual

Use vtkShaderProgram::Substitute to replace //VTK::XXX:YYY declarations in the shader sources.

Gets called after other mapper shader replacements. Return false on error.

Reimplemented in vtkShadowMapPass, vtkValuePass, vtkDepthPeelingPass, vtkDualDepthPeelingPass, and vtkOrderIndependentTranslucentPass.

virtual bool vtkOpenGLRenderPass::SetShaderParameters ( vtkShaderProgram program,
vtkAbstractMapper mapper,
vtkProp prop,
vtkOpenGLVertexArrayObject VAO = nullptr 
)
virtual

Update the uniforms of the shader program.

Return false on error.

Reimplemented in vtkShadowMapBakerPass, vtkValuePass, vtkShadowMapPass, vtkDepthPeelingPass, and vtkDualDepthPeelingPass.

virtual vtkMTimeType vtkOpenGLRenderPass::GetShaderStageMTime ( )
virtual

For multi-stage render passes that need to change shader code during a single pass, use this method to notify a mapper that the shader needs to be rebuilt (rather than reuse the last cached shader.

This method should return the last time that the shader stage changed, or 0 if the shader is single-stage.

Reimplemented in vtkValuePass, and vtkDualDepthPeelingPass.

static vtkInformationObjectBaseVectorKey* vtkOpenGLRenderPass::RenderPasses ( )
static

Key containing information about the current pass.

virtual void vtkOpenGLRenderPass::SetActiveDrawBuffers ( unsigned  int)
virtual

Number of active draw buffers.

virtual unsigned int vtkOpenGLRenderPass::GetActiveDrawBuffers ( )
virtual
void vtkOpenGLRenderPass::PreRender ( const vtkRenderState s)
protected

Call before rendering to update the actors' information keys.

void vtkOpenGLRenderPass::PostRender ( const vtkRenderState s)
protected

Call after rendering to clean up the actors' information keys.
