Yes, you can use them together. After blindly running over internate for more than 10 days, this tutorial led me on track to starts with GLSL. Before glsll shaders, in any language, it is a good idea to understand the basics of the graphics pipeline.

I mean, i want to create 3d games. This dual coverage is prone to mistakes, so please let me know if you find something wrong. Leave a Reply Cancel reply. Please bear in mind that this is work in progress and therefore bugs are likely to be present in the text or demos.

OpenGL does not manage keyboard and mouse type of chrat. Let me know if you find any bug, regardless of how insignificant, so that I can clean them up. Kevin van der Velden says: Shaders are a hot topic and 3D games have shown that they can be put to good use to get remarkable effects.

Since no new ressources is used chext each loop, the memory is going to stay stable. The differences are small, and mostly have to do with slightly different function names and constants.

Finally it is shown how an OpenGL application can feed data to a shader making it more flexible and powerful. The necessary steps to use a shader in an OpenGL application are discussed in some detail. VSmain shader compiled with errors Compilation details for VSmain shader: That are not absolutely needed? Some basic concepts such as data types, variables, statements and function definition are then introduced. Also suggestions are more than welcome.
