The book proof is finally here. I’ve had the cover for the OpenGL ES 3 tutorials book redone, and I’m sure you agree that the new cover is miles better than the original (see above). The tutorials book was intended to go with the Modern Graphics Programming Primer. Those two were supposed to be a […]
Years ago someone asked me if I would add the ability to write shader assembly to the graphics drivers I was writing. My reply was: you really don’t want to do that. I’ve been working on adding switch support to Warp3D Nova’s drivers, and decided to explain why writing GPU code is hard: Modern GPUs […]
The Modern Graphics Programming Primer book and its accompanying tutorials have been re-released in both Kindle and print formats. I’ve done this hoping that I can reach more people this way. Amazon have hundreds of millions of customers searching their site, and some people just prefer to read physical paper copies. You can get the […]
There’s bound to be people who disagree with what I’m about to write, but I’m going to write it anyway. When it comes to computer graphics programming, I think learning OpenGL ES 3+ is the way to go right now. So much so that I wrote an OpenGL ES 3 (GLES3) tutorial series and also […]
A quick heads up that I’ll be releasing a new OpenGL (ES) tutorial series soon. It’ll take you from zero through to rendering a simple 3D scene with lighting.I’ve been posting tutorials to this blog, but they’ve all been AmigaOS specific. While this nicely complements the Warp3D Nova project I’m working on, most people will […]
Recently, the AmiCraftNova author was having issues with GLSL shaders, which got me thinking about how to debug them. Shaders need debugging, but standard debugging tools can’t be used. So here are a few tips (for both OpenGL and Warp3D Nova). Check the Compiler Logs Both OpenGL and Warp3D Nova provide compilation logs. So check […]
Today I’m going to show you another way to draw coloured triangles with OpenGL (ES). It’ll look less interesting 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 ColourAs the name suggests, vertex attributes are “attributes […]
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 […]
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 […]
