1  Java Game APIs & Engines / OpenGL Development / (OpenGL or own)Matrix functions, Render a Mesh many times (Geometry Instancing?) on: 2013-01-20 16:03:51
Hi, I want to learn OpenGL using LWJGL. So far I have read the following articles.

LWJGL Basics 1 (The Display)
LWJGL Basics 2 (Input)
LWJGL Basics 3 (The Quad)
LWJGL Basics 4 (Timing)
LWJGL Basics 5 (Fullscreen)

Version selection
The Quad with DrawArrays
The Quad with DrawElements
The Quad colored
The Quad interleaved
The Quad textured
The Quad updating a VBO with BufferSubData
The Quad with Projection, View and Model matrices

Now to my questions:

1. Can anyone recommend what I should read next?
2. Does it make sense to use the matrix functions such GL11.glMatrixMode(),  GL11.glLoadIdentity() and GLU.gluPerspective() or should I immediately begin to do everything by hand, as described here?
3. How can I render a mesh(eg cubes) effectively many times? Should I do it with Geometry Instancing?
