Module camera 

View and projection transform helpers.

This module provides view matrix (look_at, look_to) and projection matrix (perspective, orthographic, frustum) constructors.

Choosing a sub-module

Pick lh or rh modules based on your world space coordinate system.

The view functions in each sub-module transform world space points into Y-up view space while preserving your world’s handedness.

Note that while the view space methods will preserve the handedness of your world’s coordinate systems, view space is a different coordinate system and will not necessarily be the same as your world coordinate system, especially if your world up is not +Y.

There are other possible view space coordinate systems, notably Y-down; however, glam only provides view and projection functions for left- and right-handed view space coordinate systems.

The corresponding projection functions expect Y-up view space input with the matching handedness.

Within each proj sub-module, pick the API-specific constructor:

Module	NDC Z	NDC Y
opengl	[-1, 1]	Up
directx	[0, 1]	Up
vulkan	[0, 1]	Down

Modules

lh

View functions produce left-handed Y-up view space with X-right and the positive Z axis pointing forward.

rh

View functions produce right-handed Y-up view space with X-right and the negative Z axis pointing forward.
