How to cast int to const GLvoid*?

Question

In my cross platform OpenGL application I want to draw using vertex buffer objects. However I run into problems invoking glDrawRangeElements.

glDrawRangeEle         


        

Answer 1

You could try to call it like this:

// The first to last vertex is 0 to 3
// 6 indices will be used to render the 2 triangles. This make our quad.
// The last parameter is the start address in the IBO => zero

glDrawRangeElements(GL_TRIANGLES, 0, 3, 6, GL_UNSIGNED_SHORT, NULL);

Please have a look to OpenGL tutorial.
