opengl-es-2.0

im searching now for a quite long time to find something working to import Blender 3D .obj files into xcode to use it on an iphone application. i cant find a description how to implement something like that anywhere! i dont want to use any engine. i just want to know the steps i have to fullfill and the basic things to do. there is really nothing on the www. you can find articles from 2005 - 2008 but thats all not up to date and nothing working. So, does anybody knows how to do that? take a look at the source in libgdx , and take a look at the objloader. He built the lib to be able to load obj

I want to use fixed function methods like glTranslate(), glRotate(), glScale() in my openGL 2.0 App. I know, that I need to implement an matrix class - and have done this. My question now is about efficiency. To be able to use something like: glLoadIdentity(); glRotatef(2.0f, 0.0f, 0.0f, 1.0f); glScalef(2.0f, 2.0f, 2.0f); I think, I need to do at least 3 matrix multiplications (assuming we have a projection and a modelview matrizes and this is for the modelview). First would be: Identity-Matrix*Rotation-Matrix - Second is: ActualMatrix*ScaleMatrix and the last would be: projectionMatrix

I am developing a 2d game on Android ICS using OpenGL es 2.0 and java. I am trying to use a lighting system and to do that I render all the lights on a framebuffer and the scene on another, with the intent to blend them using the fragment shader to recreate photoshop overlay effect. I encountered a problem though, it seems that the fbo doesn't work with multisampling, so if I draw on the fbo I get jagged lines. I noticed that there is a solution for people using ios, but I didn't find anything on Android. Is there a better way to achieve what I am trying to do than the way I am approching this
