Detailed Description

Avergae frames to simulate motion blur.

A slow and simple approach that simply renders multiple frames and accumulates them before displaying them. As such it causes the render process to be SubFrames times slower than normal but handles all types of motion correctly as it is actually rendering all the sub frames.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDepthImageProcessingPass.

◆ PrintSelf()

void vtkSimpleMotionBlurPass::PrintSelf	(	ostream &	os,

	)

overridevirtual

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 vtkDepthImageProcessingPass.

◆ Render()

void vtkSimpleMotionBlurPass::Render ( const vtkRenderState * s )

overridevirtual

Perform rendering according to a render state s.

Precondition: s_exists: s!=0

Implements vtkRenderPass.

◆ ReleaseGraphicsResources()

void vtkSimpleMotionBlurPass::ReleaseGraphicsResources ( vtkWindow * w )

overridevirtual

Release graphics resources and ask components to release their own resources.

Precondition: w_exists: w!=0

Reimplemented from vtkImageProcessingPass.

◆ GetSubFrames()

virtual int vtkSimpleMotionBlurPass::GetSubFrames ( )

virtual

Set the number of sub frames for doing motion blur.

Once this is set greater than one, you will no longer see a new frame for every Render(). If you set this to five, you will need to do five Render() invocations before seeing the result. This isn't very impressive unless something is changing between the Renders. Changing this value may reset the current subframe count.

◆ SetSubFrames()

virtual void vtkSimpleMotionBlurPass::SetSubFrames ( int subFrames )

virtual

Set the number of sub frames for doing motion blur.

Once this is set greater than one, you will no longer see a new frame for every Render(). If you set this to five, you will need to do five Render() invocations before seeing the result. This isn't very impressive unless something is changing between the Renders. Changing this value may reset the current subframe count.

◆ SetDepthFormat()

virtual void vtkSimpleMotionBlurPass::SetDepthFormat ( int )

virtual

Set the format to use for the depth texture e.g.

vtkTextureObject::Float32

◆ SetColorFormat()

virtual void vtkSimpleMotionBlurPass::SetColorFormat ( int )

virtual

Set the format to use for the color texture vtkTextureObject::Float16 vtkTextureObject::Float32 and vtkTextureObject::Fixed8 are supported.

Fixed8 is the default.
