class pygfx.utils.enums.ElementFormat

Bases: Enum

The base elements to specify formats.

These values can be used to compose formats of various layouts, e.g. 2D positions with “2xf4”, rgb colors with “3xu8” or matrices with “4x4xf32”. The purpose is to provide a common representation for simple formats, that can be used for buffers, textures and uniform buffers.
