You want to try out the Android NDK? I have gotten a lot of questions about how to setup and work with the NDK and I decided to write down how I do it. My goal with this entry is to gather all the information you need to get started with the Android NDK. I [...]

This will be an overview of that I think is the coolest scene graph philosophy ever. It will reduce the code and make your graphical framework more dynamic and easier to maintain. It is preferred that you know a bit about regular scene graphs to better grasp the idea since this is not a post [...]

Last tutorial we worked a bit more on meshes and we have also talked about adding colors to our mesh. The most common way of adding colors to your mesh is to add a texture. There is a couple of different steps involved with adding a texture to the mesh I will try to go [...]

I have been developing frameworks for different applications mostly games for over 10 years. Over this time I have made some really bad decisions and wrong turns, fortunately I have learned and gained some knowledge that always made my next framework a bit better. Design patterns One of my first lessons was that I don’t [...]

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 [...]
