SDFMeshProcessor() [2/2]

MayaFlux::Buffers::SDFMeshProcessor::SDFMeshProcessor	(	std::shared_ptr< VKBuffer >	grid_buf,
		std::shared_ptr< VKBuffer >	counter_buf,
		const glm::vec3 &	bounds_min,
		const glm::vec3 &	bounds_max,
		uint32_t	res_x,
		uint32_t	res_y,
		uint32_t	res_z,
		float	iso_level
	)

Construct in GPU-field mode with externally owned buffers.

grid_buf and counter_buf are owned by SdfPrepProcessor and pre-zeroed before this processor runs. evaluate_grid() is never called in this mode.

Parameters

grid_buf	Corner grid buffer written by SdfFieldProcessor.
counter_buf	Atomic vertex counter buffer, zeroed by SdfPrepProcessor.
bounds_min	World-space minimum corner.
bounds_max	World-space maximum corner.
res_x	Cell count along X.
res_y	Cell count along Y.
res_z	Cell count along Z.
iso_level	Isosurface threshold.
