I created ZitaFTP Server in part because I wanted secure file transfer on AmigaOS (something that wasn’t available previously). Some seem to think that plain FTP is good enough, so today I’m going to show you just how easy it is to steal passwords from plain FTP. This is something you need to be aware […]
Last week I published a teaser announcing that I was releasing ZitaFTP Server soon, but I guess an obvious question would be: why? It might surprise you that I wasn’t actually thinking of an FTP server when I started.I was just sick of the lack of good ways to transfer files between my Amiga and […]
Okay, the Warp3D Nova tutorials book is finally done. I’ve done the final edits, and it’s available now for you to buy. I’ve decided to go for the extra expense of full-colour on the print book. I know it’s more expensive, I think that the colour syntax highlighting makes the code easier to understand. So, […]
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 […]
If you’ve been following the AmigaOS world then you’ll no doubt have heard of the upcoming A1222 (codenamed Tabor). It’s a nice little board; one that I’m planning to build a laptop out of. Anyway, the P1022 CPU on-board has a peculiarity: it’s got a Stream Processing Engine (SPE) for floating-point calculations that’s incompatible with […]
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 […]
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 […]
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 […]
