This tutorial will get you started with OpenGL ES 2+ (GLES2) on AmigaOS. It’ll show you how to set up a window and render to it. The set up will be done using AmigaOS APIs directly (no GLUT, SDL or other cross-platform library).OpenGL (ES) 2+ is a popular cross-platform shader based graphics API. It’s used […]
A few weeks ago I created a survey for AmigaOS developers. The goal was to gauge developer interest in Warp3D Nova, and the OpenGL ES 2 wrapper. I want to get more developers using these new capabilities. Well, the results are in. Drum roll!First up, game development is the big winner (see the graph below). […]
It’s finally time to render in 3D using Warp3D Nova. Last time we covered the theory; now it’s time to put it into practise. There’s still a lot to learn though, so brace yourself.Step 1: PreparationStart by creating a new project in CodeBench (or whatever editor you’re using) called Tutorial5. Copy the Context, Init, and […]
The first game using Warp3D Nova has just been released. It’s a Minecraft type game for AmigaOS called AmiCraftNova. Originally written using OpenGL, AmiCraft’s author has ported it to OpenGL ES 2.0. Well done CarasGhant (his forum nickname)!I’m sure some will be thinking “that looks rather primitive.” True, AmiCraft emulates Minecraft’s blocky style which doesn’t […]
It was late morning when I got that sinking feeling. What I thought was an easy job was instead turning into a nightmare. I thought to myself, why oh why did people invent so many pointless variations? The task at hand was adding 16-bit texture support to Warp3D Nova. This needed special handling because AmigaOS […]
Yes! It’s finally time to draw in 3D. Actually, you’re not going to get far without a basic understanding of 3D geometry. So there’s still some theory to get through. Feel free to skip this if you already know what model, view and projection matrices are. Otherwise, pay close attention.I’m going to focus on core […]
In Hello Go Server Part 2 we created a server that could serve multiple pages but couldn’t serve images or other files. So, not very useful. Today, we’ll overcome this limitation so that we can serve pages with images, stylesheets (CSS), and other files. That covers everything needed for a visually stunning static website.Step One: […]
Today I’m going to show you another way to draw coloured triangles in Warp3D Nova. The result will be more boring than the previous tutorial’s method. However, it’s a good way to introduce using multiple vertex attributes and you’ll need that for almost everything from here on out.Per Vertex ColourVertex attributes are essentially “attributes that […]
Last time we wrote a simple server that says hello. That’s nice, but very limited. Let’s extend it to serve multiple pages and also add template caching for better performance.Step One: Template CachingThe previous server loads and parses templates for every single request, which is very inefficient. Templates should be parsed once and cached in […]
Last time I promised a splash of colour. The plan was to implement per vertex colouring, but I’ve got a better idea. Let’s do something that Warp3D can’t do: procedural/algorithmic “texturing” using shaders. We’re going to write shaders that generate texels on-the-fly instead of reading them from memory. Sure, the old Warp3D could render identical […]
