execute()

void visutwin::canvas::MetalLICPass::execute	(	MTL::RenderCommandEncoder *	encoder,
		Texture *	velocityTexture,

Execute the LIC pass on the active render command encoder.

Parameters

encoder	Active render command encoder.
velocityTexture	RG16Float texture with screen-space velocity per pixel.
noiseTexture	R8Unorm tiled white noise texture (e.g. 200×200).
integrationSteps	Number of steps in each direction (total kernel = 2L+1).
stepSize	Step size in normalized texture coordinates.
animationPhase	Phase offset [0, 1] for animated LIC.
contrastLo	Low end of contrast enhancement range.
contrastHi	High end of contrast enhancement range.
pipeline	Metal render pipeline for state lookup.
renderTarget	Render target for pipeline state creation.
bindGroupFormats	Bind group formats for pipeline compatibility.
defaultSampler	Linear/wrap sampler for texture reads.
defaultDepthStencilState	Fallback depth-stencil state.
