Pathtracing 2

A long time ago i wrote an introductory article on the principles of path tracing along with some initial results which were fairly uninspiring. 500 samples per pixel for this… At the time I...

Low noise improvements in action 0

War on noise

The latest version of Wooscripter has just been released and there are some major improvements to the raytracer to support lower noise final renderings with far smoother early results. I’ve already covered a fair...

The war on noise 0

2D Samplers

Today I’m covering a pretty deep technical subject, but for once the maths is straightforwards and it’s not even in 3d! The topic I’m discussing is how to distribute random numbers in such a...

Stack of rounded squares 3

Cylinder intersection

For the first time in a while I’ve added a new primitive type to the raytracer. The more I’ve messed about with procedural geometry the more I’ve become frustrated by the limit of building...

Wootracer threading

I may have been a bit quiet recently, but it’s not because I’m not working on stuff. There’s a few issues with the way that the Wootracer works which are causing me significant annoyance...

Pythagoras Tree

I started out looking into a variety of different tree fractals, but one of the earliest classes of tree fractal I found has kept me pretty busy. So today I’m going to go over...

Wooscript Extensions

Please note that this article is kept for archive purposes only, Wooscript has moved on a long way since this was written! I’ve been busily working away on Wooscript for the last few days...

3d geometry generated from stack based transformation language 0

Compound Rotations

I’ve been continuing to work on the scripting language for generating procedural objects. During the last article I introduced the basics of Wooscript. There were a few things that weren’t quite right with the...

WooScript

Now it’s time for something completely different. I came across a program called StructureSynth thanks to one of our HTML contractors at work. It allows you to define basic geometry patterns using a simple...

Outdoor Rendering

I’ve been doing lots of renders that have shown objects in a dark room, or in a cornell box, but I haven’t shown many objects in coloured outdoor environments. Well, it’s time to correct...
