Matthew Leaman recently published an article about the move to Polaris graphics cards on AmigaOS 4.x. He gave a good overview of why drivers for Polaris cards are needed and the work being done. That said, a picture is worth a thousand words, so I thought I’d give you a glimpse of the current driver […]
ERROR Last month I gave people a sneak peek at my DIY laptop project at AmiWest (and youtube). It’s been several weeks since, so it’s high time that I gave you more information. The video above gives a quick update (I’m almost done assembling a large 3D printer for prototyping), and details on the usual […]
As an AmigaOS graphics driver developer I’m always interested in knowing what graphics hardware people are actually using. This year I’ve got the most accurate picture yet, with over 3x the submissions of last year’s survey! Many thanks to the 348 people who took part.So, what does the AmigaOS 4 graphics landscape look like? Well, […]
I recently discovered that Daniel Müßener has been secretly working away on a new project. Have a look here (link). If you’re an AmigaOS 4 fan, then yes, this is what you think it is; it’s a Warp3D Nova version of MiniGL.This is great news, especially for owners of old hardware. MiniGL’s biggest limitation has […]
Yes, I’ve discovered another bug in one of the Warp3D Nova tutorials. The tutorial itself has been corrected already, but let’s take a closer look at this bug. The problem is with this line of code: // Transform the normal normal = normalize(NormalMatrix * vec4(vertNormal, 1.0)).xyz; Can you see the mistake? It’s a really subtle […]
The author of AmiCraftNova recently released a new demo called StarBoxDemo. While everyone has been posting new fps benchmarks with it, how it uses shaders should be of greater interest to aspiring developers. So download the demo (if you haven’t already), and take a look in the Shaders directory.The big advantage of shaders is that you […]
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 […]
Alain Thellier recently ported his Cow3D demo/test-program to Warp3D Nova, which allows Warp3D Nova and Warp3D to be compared. Results have been coming in thick and fast, along with speculations as to why the results are what they are. I was expecting Nova to deliver a larger boost, and it actually does; it’s just partially hidden. […]
The previous tutorial’s source-code included animation, but I said that would be a topic for another day. Well, today is that day. I’m going to go through the code I added to animate the cube. IMPORTANT: While this tutorial is about Warp3D Nova, the animation code below is almost 100% generic. You could reuse it to […]
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 […]
