OpenGL rendering window.
abstract superclass for all actors, volumes and annotations
Definition: vtkProp.h:45
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int ViewportWidth
Cache viewport values for depth peeling.
window superclass for vtkRenderWindow

Context in which a vtkRenderPass will render.
OpenGL state storage.
a simple class to control print indentation
Definition: vtkIndent.h:28
Internal class which encapsulates OpenGL FramebufferObject.
abstract class specifies interface to map data
abstracts an OpenGL texture object.
virtual void Render(const vtkRenderState *s)=0
Perform rendering according to a render state s.
Class to make rendering a full screen quad easier.
virtual void ReleaseGraphicsResources(vtkWindow *w)
Release graphics resources and ask components to release their own resources.
int ViewportHeight

static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
Perform part of the rendering of a vtkRenderer.
Definition: vtkRenderPass.h:48
Abstract render pass with shader modifications.
virtual bool PostReplaceShaderValues(std::string &vertexShader, std::string &geometryShader, std::string &fragmentShader, vtkAbstractMapper *mapper, vtkProp *prop)
Use vtkShaderProgram::Substitute to replace.
int ViewportX
Cache viewport values for depth peeling.
Implement OIT rendering using average color.
