Py5Graphics.apply_matrix()

Multiplies the current matrix by the one specified through the parameters.

Description

Multiplies the current matrix by the one specified through the parameters. This is very slow because it will try to calculate the inverse of the transform, so avoid it whenever possible. The equivalent function in OpenGL is gl_mult_matrix().

This method is the same as apply_matrix() but linked to a Py5Graphics object. To see example code for how it can be used, see apply_matrix().

Underlying Processing method: PGraphics.applyMatrix
