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 […]
When I redesigned this website, I ended up adapting a theme that was based on Twitter’s Bootstrap framework. While this looked good and worked well, there was one area where Bootstrap failed to deliver: the drop-down menus.Bootstrap is designed to be mobile friendly, which is great. On mobile devices everything is done with (fat) fingers […]
The Go language’s standard library comes complete with components for creating “web applications.” This is one of the things that attracted me to Go in the first place. So, today we will cover the basics needed to create a simple web-server in Go.This tutorial uses the Atom code editor based development environment from the previous […]
The previous tutorial set up everything needed to render graphics to a window using Warp3D Nova. Now, it’s time to actually draw something. This tutorial will introduce you to shaders and Vertex Buffer Objects (VBOs), and we’ll use them to draw a triangle.A Shader Based PipelineAt its core, modern Graphics Processing Units (GPUs) are based […]
While the Go language has a web-based playground, for serious work you’re better off with a locally installed development environment. This tutorial will show you how to set up a local “Go dev. environment,” all the way through to writing and running your first (really basic) program.NOTE: While some of the instructions here are Windows […]
