gmath

Header-only math library for linear (and non-linear) transformations made to work with OpenGL.

Features

• Matrix class
• Vector class
• Transformations
  • Translation
  • Rotation
  • Scale
• Projections
  • Orthographic
  • Perspective

Notes

• in memory matrices are laid out in row-major order, therefore transpose prarmerer in glUniformMat** shuld be set to GL_TRUE when sending matrix to a shader
• order of matrix multiplication is reversed (just like in glm)

Example usage

#include <gmath>

gm::mat4 model = gm::rotate(gm::mat(1.f), gm::vec3(0.f, 0.f, 1.f), gm::randians(90.f));
gm::mat4 view = gm::lookAt(gm::vec3(-1.f, 0.f, 0.f), gm::vec3(0.f, 0.f, 0.f), gm::vec3(0.f, 1.f, 0.f));
gm::mat4 projection = gm::perspective(gm::radians(60.f), 4.f/3.f, 0.1f, 100.f);

gm::mat4 MVP = projection * view * model;
