Looking through documentation for vertex arrays in OpenGL, two of the most common memory types used for indices I found were GLubyt开发者_JS百科e (GL_UNSIGNED_BYTE) and GLshort (GL_SHORT).
Assume you have an array of values that will need to be summed together d = [1,1,1,1,1] and a second array specifying which e开发者_Go百科lements need to be summed together
