AcquirePointAttributeComputeRenderBuffer()

vtkSmartPointer< vtkWebGPUComputeRenderBuffer > vtkWebGPUPolyDataMapper::AcquirePointAttributeComputeRenderBuffer	(	PointDataAttributes	attribute,
		int	bufferGroup,
		int	bufferBinding,
		int	uniformsGroup,
		int	uniformsBinding
	)

Returns an already configured (ready to be added to a vtkWebGPUComputePipeline) buffer bound to the given group and binding.

All point data (positions, normals, colors, ...) of this mapper is contained within the single returned buffer. To access the requested (specified by 'attribute') part of the buffer, an offset and a length are automatically bound as uniforms on the 'uniformsGroups' and 'uniformsBinding' given. The offset can then be used in the shader to access the relevant part of the buffer while the length can be used for bounds checking

Warning

: The returned buffer is already configured and should immediately be inserted into a compute pipeline via vtkWebGPUComputePipeline::AddBuffer() without further modifications through vtkWebGPUComputeBuffer setter methods (other than SetLabel())

AcquireCellAttributeComputeRenderBuffer()

vtkSmartPointer< vtkWebGPUComputeRenderBuffer > vtkWebGPUPolyDataMapper::AcquireCellAttributeComputeRenderBuffer	(	CellDataAttributes	attribute,
		int	bufferGroup,

ComputeBounds()

void vtkWebGPUPolyDataMapper::ComputeBounds ( )

overrideprotectedvirtual

Called in GetBounds().

When this method is called, the consider the input to be updated depending on whether this->Static is set or not. This method simply obtains the bounds from the data-object and returns it.

Reimplemented from vtkPolyDataMapper.

CacheActorRendererProperties()

bool vtkWebGPUPolyDataMapper::CacheActorRendererProperties ( vtkActor *  actor, vtkRenderer *  renderer  )

protected

This method keeps track of few properties of the actor which when changed, require rebuilding a render bundle.

For example, if representation changed from wireframe to surface, the last set of draw commands were recorded using the SurfaceMesh pipeline. In order to draw wireframes, the render bundle will need to be rebuilt using the wireframe pipeline instead.

This method returns true if the cached properties have changed or the properties of the actor are cached for the first time, false otherwise.

void vtkWebGPUPolyDataMapper::RecordDrawCommands ( vtkRenderer *  renderer, vtkActor *  actor, const wgpu::RenderPassEncoder &  passEncoder  )
