  1. Hello. I am having trouble making a simple example in libgdx. I want to make use of friction joints in order to simulate floor friction in top-down games but I can't get it to work. I asked about this in Stack Overflow but since I am not getting response I wanted to try here. This is the link of the question: http://stackoverflow.com/questions/37208634/libgdx-box2d-friction-joint-not-working   Cheers.
  2. Hello, I am new at 3D game programming. I have decided to get started using Irrlicht and bullet. Since I am starting I have many doubts about how 3D games are made.   I was wondering how collision is usally implemented. Let me explain, I have read that you can make a model in blender and export to a bullet format and also export to a format that Irrlicht can read for rendering. Then you can update the Irrlicht position and rotation from the position and rotation bullet returns as a result. But many times I think this way of doing things can improved in terms of efficiency. For exaple, look at this 3D model:   Do I really need that fence to be that so detailed in the bullet model? I don't think so. Probably the fence is not going to move and probably I don't want small objacts to go through the fence. I think that a box would be a good simplification. In general, I think that many times models could be  simplified in a small set of very simple shapes. Are the kind of simplifications done in practice? Are they handcrafted or produced automatically? What happens when skeletan animation is involved?   Thanks and sorry for my english.
  3. Do you mean that the code is portable no mather the version you are using? Can I compile one code and choose the target OpelGL specification?  Thanks for the replies!
  4. I don't use any IDE I use g++ under ubuntu 13. The version of OpenGL is 2.1. Thanks!
  5. Oh, really? I didn't know that, in fact, I thought it was the other way around(that older versions where more portable). Then I wonder why I culdn't compile the examples of the book I said. I get this error message: tut1.cpp:10:32: error fatal: glload/gl_3_2_comp.h: No existe el archivo o el directorio Which means that the file or folder doesn't exist. Thanks for the answer!
  6. Hi everyone. I am new to OpenGL and also to this forum. I wanted to know which are the benefits of using the newest specifications of OpenGL. Is it not better to use the older versions so more computers are able to run my game? I ask this because I have been reading this online book Learning Modern 3D Graphics Programming and it uses newer version of OpenGL than mine and I can not even compile the examples. Thanks in advance.
