-- ABOUT --

glmr - or "glimmer" (OpenGL Mathematics Replacement) - is a (fairly) modular subset replacement to some cglm functions

The aim is to allow for certain (graphical) mathematic calculations without the need to include the complete library; you can lift out and use only the functions you require for your project.

I am trying to avoid internal dependencies when possible, so in any future updates, helper code may be duplicated inside functions that depend on them.

-- HELPERS --

glmr_sqrt()  
glmr_tanf()

-- DROP-IN REPLACEMENTS --

glmr_lookat()
glmr_mat4_copy()
glmr_mat4_identity()
glmr_mat4_inv()
glmr_mat4_translate()
glmr_ortho()
glmr_perspective()
glmr_rad()
glmr_vec3_add()
glmr_vec3_copy()
glmr_vec3_cross()
glmr_vec3_norm2()
glmr_vec3_normalize)
glmr_vec3_sub()

To avoid potential conflicts with other includes, the following type definitions are recommended to use with glmr:

typedef float glmr_vec2[2];
typedef float glmr_vec3[3];
typedef float glmr_mat4[4][4];

#define GLMR_MAT4_IDENTITY_INIT {{1.0f, 0.0f, 0.0f, 0.0f}, \
                                {0.0f, 1.0f, 0.0f, 0.0f}, \
                                {0.0f, 0.0f, 1.0f, 0.0f}, \
                                {0.0f, 0.0f, 0.0f, 1.0f}}

#define GLMR_PI 3.14159265358979323846

-- ARE THESE FEATURE COMPLETE? --

glmr is far from complete, and include only the functions I currently use with my projects. It is not meant to be a replacement to the cglm library. The included functions may or may not be optimized or full featured.

As the scope is focused on size optimization over efficiency, I strongly recommend you to do your own benchmark tests to compare cglm with glmr
