Mantra tests

January 22, 2017

Blurry and glossy spec reflections, SSS, DOF, all the usual suspects. Able to get it under 7 minutes on my shitty i7.

3D Prints

December 18, 2016

So I’ve finally bought a printer. A Zortrax M200 to be exact. Great machine. Rigid construction and a nice closed loop ecosystem. Which means consistent prints.

Houdini Coordinate System

December 18, 2016

Here’s a quick visual for understanding the right-hand coordinate system that Houdini uses. Note in the second image, if you point your thumb in the + direction of an axis, and curl your fingers, the curl direction is the positive direction for rotation around that axis.

This is a product of being a right-hand coordinate system. It also controls the default direction of the cross product.
