This module is about comparison of floating point arithmetics. Supported by this very informative article: https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/
Matrix determinant and inverse
Matrix linear algebra module
Projection matrices Assumption is made that the model-view coordinates are right-handed, with X to the right, Y up, and Z out of the screen. A second assumption is that in the final normalized clipping space, Z points into the screen. The projection transforms have two options (DepthClip and NDC) that will affect how the coordinates are transformed in the final normalized clipping space. NDC affects only X and Y (X always to the right, Y either upwards or downwards for leftHanded and rightHanded respectively), and DepthClip affects Z depth range.
