Convenient class for post-processing passes.
a simple class to control print indentation
Definition: vtkIndent.h:38
Internal class which encapsulates OpenGL FramebufferObject.
Class to make rendering a full screen quad easier.
OpenGL rendering window.
Render pass that render the scene in a cubemap and project these six renderings to a single quad.
void InitOpenGLResources(vtkOpenGLRenderWindow *renWin)
void SetProjectionTypeToEquirectangular()
Get/Set the type of projection.
static vtkPanoramicProjectionPass * New()
void Project(vtkOpenGLRenderWindow *renWin)
~vtkPanoramicProjectionPass() override=default
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void RenderOnFace(const vtkRenderState *s, int index)
void Render(const vtkRenderState *s) override
Perform rendering according to a render state.
vtkPanoramicProjectionPass()=default
void ReleaseGraphicsResources(vtkWindow *w) override
Release graphics resources and ask components to release their own resources.
void SetProjectionTypeToAzimuthal()
Get/Set the type of projection.
