In GLM, common methods for 4x4 matrices commonly used in OpenGL include:



glm::mat4 a = glm::mat4(1);
glm::mat4 b = glm::translate(a, glm::vec3(1, 0, 0));
glm::mat4 c = glm::rotate(b, 0.0f, glm::vec3(0, 1, 0));
glm::mat4 d = glm::scale(c, glm::vec3(2, 1, 1));
glm::mat4 e = glm::inverse(d);

The modeling matrix is initially set to the identity matrix.  In GLM, this can be achieved using:

glm::mat4 mModelMatrix = glm::mat4(1);
