VolumeSurfaceProcessor()

MayaFlux::Buffers::VolumeSurfaceProcessor::VolumeSurfaceProcessor	(	std::shared_ptr< VolumeGridBuffer >	volume,
		std::string	field_name,
		Kinesis::Lattice3D	lattice,
		float	threshold,
		const std::string &	shader_path = "volume_to_sdf_grid.comp.spv"
	)

Construct a surface extraction bridge.

Parameters

volume	Volume whose field is resampled.
field_name	Name of the scalar field resampled. Must have stride sizeof(float).
lattice	Extraction lattice, normally the volume's own lattice resampled to a different resolution over the same bounds.
threshold	Field value the surface is placed at.
shader_path	Path to the compute shader.
