Detailed Description

GPU Marching Cubes isosurface extraction via Metal compute kernels.

Owns compute pipelines, lookup table buffers, and atomic counter buffer. Each extract() call allocates a fresh output vertex buffer that is transferred to the caller (per-extraction ownership).

Thread-unsafe – call from the main rendering thread only.

Member Function Documentation

◆ extract()

MCExtractResult visutwin::canvas::MetalMarchingCubesPass::extract	(	Texture *	volumeTexture,
		const MCComputeParams &	params )

Extract an isosurface from a 3D volume texture. Each call allocates a new output buffer — the caller takes ownership.

Parameters

volumeTexture	3D texture (R32Float) containing scalar volume data.
params	Extraction parameters (isovalue, dims, domain, etc.).

Returns: Extraction result with vertex buffer and count.

◆ extractBatch()

MCBatchResult visutwin::canvas::MetalMarchingCubesPass::extractBatch	(	Texture *	volumeTexture,
		const MCComputeParams &	baseParams,
		const std::vector< float > &	isovalues,
		const std::vector< bool > &	flipNormals = {} )

Extract multiple isosurfaces in a single batch call. Each layer gets its own output buffer — the caller takes ownership.

Parameters

volumeTexture	3D texture (R32Float) containing scalar volume data.
baseParams	Base extraction parameters (dims, domain, texelSize shared).
isovalues	Isovalue for each layer.
flipNormals	Per-layer flip normal flags (same size as isovalues).
