Graphmath.Mat44.apply_left

You're seeing just the function apply_left, go back to Graphmath.Mat44 module for more information.

apply_left(v, a)

apply_left(vec4(), mat44()) :: vec4()

apply_left( v, a ) transforms a vec4 by a mat44, applied on the left.

a is the mat44 to transform by.

v is the vec4 to be transformed.

This returns a vec4 representing v**A**.

This is the "full" application of a matrix, and uses all elements.
