Last time I showed you how to set up a windowed OpenGL ES 2 (GLES2) context on AmigaOS. Now lets draw something. This tutorial will show you how to use shaders to draw stuff (a simple triangle, in this case).It closely follows a similar Warp3D Nova tutorial, and you’re welcome to compare the two.NOTE: While […]
Curious how OpenGL ES 2 (GLES2) + Warp3D Nova’s performance compares to MiniGL + Warp3D? Well, the first comparison is here courtesy of the Entwickler-X team. They’ve just released (as at 1 Nov. 2016) a video showing an upcoming game running on both MiniGL and GLES2. The game is built using X-Engine, a game engine […]
Like other Application Programmers Interfaces (APIs), Warp3D Nova has little “gotchas” that catch programmers out. These are common pitfalls that new programmers fall into. Even experienced programmers can make these mistakes; yes, even the API’s designer (i.e., me).Binding Vertex Arrays to the Wrong Shader InputsSetting up vertex arrays is a multi-step process and there are […]
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 […]
I’ve just come back from the AmiWest show. It’s the first time that I’ve attended, and it was great to be there. I got to:Meet and chat with other Amiga users & developers Listen to Bob “Kodiak” Burns (one of the original developers) talk about developing the Amiga and working for Commodore Hear Colin Proudfoot’s […]
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 […]
Alan Kay said, “People who are really serious about software should make their own hardware.” Not sure that I agree, but I’m definitely a software engineer who likes to make his own hardware. This tutorial will lay the foundations for hardware design using relatively low-cost tools.Why design your own hardware? A few possible reasons:It gives […]
