Detailed Description

Caches a compiled wgpu::RenderPipeline for the Slug gradient-fill shader plus its bind-group layout.

Parallel to GeodePipeline but with a larger uniform buffer that carries linear-gradient parameters (pathFromGradient transform, start/end, spread mode, per-stop colors and offsets). The vertex layout, Band / curve storage bindings, and blend state are identical.

Kept as a sibling class instead of a branch inside GeodePipeline to keep the solid-fill pipeline's 128-byte uniform layout untouched, and so radial / sweep gradient pipelines can slot in alongside this one later without churning the solid-fill path.

Constructor & Destructor Documentation

GeodeGradientPipeline()

donner::geode::GeodeGradientPipeline::GeodeGradientPipeline	(	const wgpu::Device &	device,
		wgpu::TextureFormat	colorFormat,
		bool	useAlphaCoverageShader = false,
		uint32_t	sampleCount = 4 )

Construct a gradient pipeline for the given device and color target format.

Parameters

useAlphaCoverageShader	When true, selects the alpha-coverage shader variant.
sampleCount	MSAA sample count (1 for alpha-coverage, 4 otherwise).
