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 […]
Last time we got the simplest of digital circuits working: an LED flasher. Now its time to move on to something more interesting. We’re going to design a serial communication module so that our hardware can communicate with other devices.Communication instantly adds an element of interactivity. We’ll be able to send commands to the hardware […]
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 […]
Alan Kay once said, “People who are really serious about software should make their own hardware.” I’m not sure that I agree, but I’m definitely one of those software engineers who would like to make his own hardware. This tutorial will lay the foundations for designing hardware using relatively low-cost tools.Why design your own hardware? […]
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 […]
This is the first of what’s going to be a tutorial series for developing software with Warp3D Nova. By the time you’ve completed this tutorial, you’ll have a basic Warp3D Nova app running. It’ll have a resizable (albeit blank) window, a Warp3D Nova context, and a basic event loop for processing user input and redrawing […]
I’ve recently started learning a new programming language: Go (a.k.a., Golang). Learning a new language is something that I’ve been putting off, preferring to earn a living with what I already know instead. However, the tech. world changes quickly, and those of us who work in it need to adapt.That’s not to say that languages […]
