OrderIndependentTranslucentPass

Source (.js)Source (.d.ts)

Introduction

vtkWebGPUOrderIndependentTranslucentPass renders translucent geometry with weighted blended order-independent transparency. Color and revealage accumulate into two floating point textures, which a full screen quad then resolves onto the opaque pass color texture, so the result does not depend on the order the translucent actors are drawn in.

Methods

createFinalEncoder

Create the render encoder the resolve pass is drawn with.

createRenderEncoder

Create the render encoder the translucent actors accumulate through, including the shader replacement computing the depth weighting.

extend

Method used to decorate a given object (publicAPI+model) with vtkWebGPUOrderIndependentTranslucentPass 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	IWebGPUOrderIndependentTranslucentPassInitialValues	No	(default: {})

finalPass

Draw the full screen quad resolving the two accumulation textures onto the color texture view set on this pass.

Argument	Type	Required	Description
viewNode	vtkWebGPURenderWindow	Yes	The render window view node.
renNode	vtkWebGPURenderer	Yes	The renderer view node, used for its scissor and viewport.

getColorTextureView

Get the view of the texture the resolved color is drawn onto.

getDepthTextureView

Get the view of the depth texture the accumulation pass tests against.

getFullScreenQuad

Get the full screen quad that composites the accumulation textures.

getTextures

Get the color and revealage accumulation textures, in that order.

getTranslucentResolveAccumulateTexture

Get the resolved accumulation target used when multisampling is enabled.

getTranslucentResolveColorTexture

Get the resolved color target used when multisampling is enabled.

newInstance

Method used to create a new instance of vtkWebGPUOrderIndependentTranslucentPass.

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

releaseGraphicsResources

Drop both encoders, both accumulation textures and the full screen quad so that they are recreated on the next traversal.

setColorTextureView

Set the view of the texture the resolved color is drawn onto.

setDepthTextureView

Set the view of the depth texture the accumulation pass tests against.

traverse

Accumulate the translucent actors of a renderer into the color and revealage textures, then resolve them onto the color texture view set on this pass.

Argument	Type	Required	Description
renNode	vtkWebGPURenderer	Yes	The renderer view node to traverse.
viewNode	vtkWebGPURenderWindow	Yes	The render window view node.
