Beginning Android 4 Games Development

Summary

Again, we have uncovered a lot of mysteries in the world of game programming. We talked a little bit about vectors in 3D, which turned out to be as simple to use as their 2D counterparts. The general theme is: Just add a z-coordinate! We also took a look at lighting in OpenGL ES. With the helper classes we wrote to represent materials and light sources; it is pretty simple to set up the lighting in a scene. For better performance and fewer graphical artifacts, we also implemented simple mipmapping as part of our Texture class. We also explored implementation of simple Euler and look-at cameras, using very little code and a little help from the Matrix class.

Since creation of 3D meshes by hand in code is tedious, we also looked at one ...
