Enumeration Type Documentation

◆ CoordSpace

enum class blender::bke::pbvh::pixels::CoordSpace

strong

Coordinate space of a coordinate.

Enumerator

UV

Coordinate is in UV coordinate space. As in unmodified from mesh data.

Tile

Coordinate is in Tile coordinate space.

With tile coordinate space each unit is a single pixel of the tile. Range is [0..buffer width].
