Questions tagged [matrix]
A matrix is a mathematical object consisting of a rectangular array of (in blender's case) numbers. Matrices are used in 3D graphics for computing coordinate transformations. Blender uses matrices in the material node system for this purpose and internally for similar purposes. The internal representation can be accessed through bpy. Use this tag for questions about matrices in either the node editor or python.
