Quite some time ago I was trying to cook up something like the guys at moviebarcode.com: Some setups that’d deconstruct a given movie into its individual colors in a visually pleasing manner. Recently I thought it was time to try another attempt. Instead of linearly mapping the individual frames’ colors on a 2D plane, this time I wanted to create something that took advantage of 3D space.
When we saw Andy Lomas’ “Aggregation” series a few years back we were struck. How could you generate those intricate particle sculptures? The series’ title hinted at one possible solution: Diffusion limited aggregation or DLA. In this tutorial we’ll build a basic DLA setup using VEX and volumes. Also we’ll talk a bit about rendering our result in Mantra and Redshift.
When testing out a new render engine (or any tool that can do rendering), one of the typical objects I try to get a decent image of is a quartz crystal. In order to get that right, a rendering needs to contain effects such as dispersion, proper refractions and SSS. In this tutorial I’ll walk you through my first attempt to render a Quartz in Mantra in H16.
