OpenGL 4.3 object instancing (Red Book Chapter 3) This properly happened because some of the other examples had a model_matrix array in the vertex shader, but in this example it must be set to 1
GlUniformMatrix4fv(render_model_matrix_loc, 4, GL_FALSE, model_matrix) The original source had a bug when model_matrix was set: Redbook_chapter_03_drawcommands_SDL2_GLM.zip OpenGL 4.3 draw commands using SDL2 glew and glm In Linux you only need to install SDL2, glew and glm development packages using your favourite package manager.Īn important note when using glew with OpenGL 4.4 / 4.3 is to set There are simple build scripts for Linux but the source should compile on any system with SDL2, glew(1.10) and glm(0.9.5.1) I don’t really have the skills to write an OpenGL 4 tutorial, so if you need guidance beyond the source and the comments, I strongly recommend buying the Red Book (8th edition). The reason for doing this, is to make them easily compile on any system with support for SDL2/GLEW/GLM (Currently I have only tested on 64bit Linux with Nvidia 340.24 drivers) I’ve also moved any auxiliary source files and data files to each example folder so that every example can be compiled independently from frameworks/etc. This page contains Red Book (8th edition) OpenGL 4.x example code that I have ported to SDL2 using glm and glew.
