drawing a pixel two times

29 June 2011 - 08:12 AM


I'm checking information about a way to make a colision detection with openGL methods. A way to detect this is looking if a pixel is drawed two times (two objects in the same place). So, is there somewhere a place to find information about this?


Troubles with glEnableVertexAttribArray

16 May 2011 - 01:21 PM


I'm trying to render a robot which has 7 joints. Each joint is an object called "Joint". I load the vertices correctly but I don't know why I can just see the first joint. I new in openGL so I don't understand very well if my calls are correct or not and the reason why...

Here you can check my code:

vertexArray is the array where I put my vertexs points previously.
GLuint vertexs;
glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 0, 0);

the render function:
void Joint::render(){ glDrawArrays(GL_TRIANGLES,0,sizeVertex);}

Can you see a problem? Thanks
