◆ grow_dijkstra()

void blender::render::texturemargin::TextureMarginMap::grow_dijkstra ( int margin )

inline

Use dijkstra's algorithm to 'grow' a border around the polygons marked in the map. For each pixel mark which direction is the shortest way to a face.

◆ lookup_pixels()

void blender::render::texturemargin::TextureMarginMap::lookup_pixels	(	ImBuf *	ibuf,
		char *	mask,
		int	maxPolygonSteps )

inline

Walk over the map and for margin pixels follow the direction stored in the bottom 3 bits back to the face. Then look up the pixel from the next face.
