The OpenGL 3.0 specification deprecated some features, and most of these have been removed from the OpenGL 3.1 specfication and beyond. GLM provides some replacement functions. Many of these functions come from the GLM_GTC_matrix_transform: Matrix transform functions. extension.
OpenGL function replacements
- glRotate[fd]
- glm::rotate
- glScale[fd]
- glm::scale
- glTranslate[fd]
- glm::translate
- glLoadIdentity
- The default constructor of all matrix types creates an identity matrix.
- glMultMatrix[fd]
- Per the GLSL specification, the multiplication operator is overloaded for all matrix types. Multiplying two matrices together will perform matrix multiplication.
- glLoadTransposeMatrix[fd]
- glm::transpose
- glMultTransposeMatrix
- Combine the last two.
- glFrustum
- glm::frustum
- glOrtho
- glm::ortho
- gluLookAt
- glm::lookAt
GLU function replacements
- gluOrtho2D
- glm::ortho
- gluPerspective
- glm::perspective
- gluProject
- glm::project
- gluUnProject
- glm::unProject
