Methods

buildPass

Resolve the ancestors this mapper renders with and bind it to its renderer.

Argument	Type	Required	Description
prepass	Boolean	Yes	Whether the traversal is on its way down.

extend

Method used to decorate a given object (publicAPI+model) with vtkWebGPUImageCPRMapper characteristics.

Argument	Type	Required	Description
publicAPI		Yes	object on which methods will be bounds (public)
model		Yes	object on which data structure will be bounds (protected)
initialValues	IWebGPUImageCPRMapperInitialValues	No	(default: {})

getCoincidentParameters

Get the polygon offset the renderable asks for, or null when it does not resolve coincident topology with a polygon offset.

newInstance

Method used to create a new instance of vtkWebGPUImageCPRMapper.

Argument	Type	Required	Description
initialValues	IWebGPUImageCPRMapperInitialValues	No	for pre-setting some of its content

opaquePass

Render the reformat during the opaque pass.

Argument	Type	Required	Description
prepass	Boolean	Yes	Whether the traversal is on its way down.

opaqueZBufferPass

Capture the reformat depth during the opaque z-buffer pass.

Argument	Type	Required	Description
prepass	Boolean	Yes	Whether the traversal is on its way down.

render

Render the reformat.

replaceShaderClip

Shader replacement, registered under replaceShaderClip, emitting the clipping plane test in model coordinates.

Argument	Type	Required	Description
hash	String	Yes	the pipeline hash
pipeline	vtkWebGPUPipeline	Yes

replaceShaderCoincident

Shader replacement, registered under replaceShaderCoincident, emitting the depth offset the renderable's coincident topology resolution asks for.

Argument	Type	Required	Description
hash	String	Yes	the pipeline hash
pipeline	vtkWebGPUPipeline	Yes

replaceShaderImageCPR

Shader replacement, registered under replaceShaderImageCPR, emitting the quad positions along the centerline and the volume sampling that straightens the image.

Argument	Type	Required	Description
hash	String	Yes	the pipeline hash
pipeline	vtkWebGPUPipeline	Yes

replaceShaderRenderEncoder

Shader replacement, registered under replaceShaderRenderEncoder, writing the prop identifier when the encoder is the hardware selector's.

Argument	Type	Required	Description
hash	String	Yes	the pipeline hash
pipeline	vtkWebGPUPipeline	Yes

translucentPass

Render the reformat during the translucent pass.

Argument	Type	Required	Description
prepass	Boolean	Yes	Whether the traversal is on its way down.

updateColorTexture

Build or reuse the texture holding the sampled color transfer functions.

updateGeometry

Rebuild the quad strip following the centerline, one quad per centerline segment, with its positions, orientations and distances.

updateOpacityTexture

Build or reuse the texture holding the sampled piecewise opacity functions.

updateUBO

Recompute and send the mapper uniform buffer when the renderable, the actor, the property, the image or the stabilized center changed.

updateVolumeTexture

Bind a texture view of the input image as the volume this mapper samples.

zBufferPass

Render the reformat depth only, so that a later pass can mix geometry with volumes.

Argument	Type	Required	Description
prepass	Boolean	Yes	Whether the traversal is on its way down.
