I have a feeling that some of you have tried my tutorials and then thought “This is a 3D tutorial, but why is everything in 2D?”. So in this tutorial we will make some real 3D meshes. This is also necessary for the following tutorials. When I started I had problems with finding out how [...]

Last tutorial was about transformations. This tutorial will be a short one. I’m going to talk about adding color to your mesh. I will continue with the source code from tutorial II. Adding color 3D models with no colors are pretty boring so let’s add some color to it. In general colors need no explanation. [...]

Last tutorial was about building your polygons. This tutorial is all about transformations, how to move the polygons around. I will continue this tutorial from where the previous ended so you can use that source code or make a copy of it. I am not going to bore you with a lot of mathematics but [...]

Previous tutorial was all about setting up the GLSurfaceView. Be sure to read it beacuse it’s a really importent one to be able to continue. Building a polygon In this tutorial we will render our first polygon. 3D models are built up with smaller elements (vertices, edges, faces, and polygons) which can be manipulated individually. [...]

I’m going to write a couple of tutorials on using OpenGL ES on Android phones. The theory of OpenGL ES is the same on different devices so it should be quite easy to convert them to another platform. I can’t always remember where I found particular info so I might not always be able to [...]
