◆ calc_cavity_factor()

void blender::ed::sculpt_paint::auto_mask::Cache::calc_cavity_factor	(	const Depsgraph &	depsgraph,
		const Object &	object,
		const IndexMask &	node_mask )

Calculates the cavity factor for a set of nodes.

Has no effect on an individual node level if the factor for a vertex has already been calculated. This data is best calculated outside of any loops that affect the stroke's position, as the curvature calculation is sensitive to small changes, meaning processing inside the normal brush update step may result in odd artifacts from ordering of position updates.

Note: Should be called prior to any call that may use the cavity mode.

Member Data Documentation

◆ cavity_factor

Array<float> blender::ed::sculpt_paint::auto_mask::Cache::cavity_factor

Cached cavity factor values for each vertex.

Note: -1 means the vertex value still needs to be calculated.

◆ factor

Array<float> blender::ed::sculpt_paint::auto_mask::Cache::factor

Cached factor for auto-masking modes that are implemented to process the entire mesh.

◆ occlusion

Array<OcclusionValue> blender::ed::sculpt_paint::auto_mask::Cache::occlusion

Cached occlusion values for each vertex. Since calculating the occlusion is so expensive, it's only calculated at the beginning of a stroke and stored for later.

Todo: Ideally the "unknown" state would be stored per node rather than per vertex, with a lock-protected Map<const bke::pbvh::Node , BitVector<>> for example. Currently complications with face domain auto-masking prevent this though. This array can't be a bitmap because it's written to from multiple threads at the same time.
