vtkWeakPointer< vtkWebGPUComputePass > vtkWebGPUComputeRenderTexture::GetAssociatedComputePass ( )

Get/set the associated compute pass.

The associated compute pass is going to be needed if we want to resize the render texture after a render window resize (for example). This is because after a resize, we'll have to recreate the texture views which means that we'll need access to the compute pass.

◆ SetAssociatedComputePass()

void vtkWebGPUComputeRenderTexture::SetAssociatedComputePass ( vtkWeakPointer< vtkWebGPUComputePass > computePass )

Get/set the associated compute pass.

The associated compute pass is going to be needed if we want to resize the render texture after a render window resize (for example). This is because after a resize, we'll have to recreate the texture views which means that we'll need access to the compute pass.
