Opengl offset

WebBy default, OpenGL will draw points with a size of a single fragment. However, as you saw in Chapter 2, “Our First OpenGL Program”, you can change the size of points that OpenGL draws by calling glPointSize(). The maximum size that OpenGL will draw your points is implementation defined, but it will be least 64 pixels. WebOpenGL ES 2 for Android - Kevin Brothaler 2013-06-26 Printed in full color.

Offset the indices you fetch from the buffer This means that you want to draw the same range of indices, but you want to apply an offset to those index values themselves. So if your index buffer looks like this: (1, 4, 2, 0, 5, ...), and you apply an offset of 20, then it will fetch these indices: (21, 24, 22, 20, 25, ...). http://duoduokou.com/cplusplus/40860254983443202473.html
