Earlier this year at Tokyo Demo Fest 2016, we were honored with the presence of Solid Angle‘s founder, Marcos Fajardo, who did a long presentation of the Arnold renderer. Various examples of productions that involved Arnold were included, like captures from Iron Man or Elysium, but between those blockbusters one production in particular held my attention.
It was a long shot of a dancer turning limb after limb into a lattice body while performing. That film is in fact the music video of the song “Wide Open”, by the Chemical Brothers, and directed by Dom&Nic. It is a brilliant piece of technical and artistic work, that I can only recommend to watch.
Earlier this year filmmaker Stu Maschwitz posted on Twitter a series of messages recounting the work he did, as a then junior visual effects artist, on the scene of the house crashing on the road in the 1996 summer blockbuster, Twister. He later copied them to his website: go read it there.
The story comes with a fair amount of detail, hacks and tricks to make the best of the technical limitations of the time, and gives an idea of the amount of work such a scene in a prominent Hollywood film entails.
Twenty years ago today, TWISTER was released. I’m going to share a bit about my involvement in the film. pic.twitter.com/6RBphItaLT
Texture artist Jarrod Hasenjager posted a page of various metal materials study: aluminum, brass, bronze, chrome, copper, gold, iron, lead and steel, and rusted steel and iron. According to the description, the renders are done in Houdini, and the look is driven by artistic taste and personal experience rather than from physical values.
A variety of mappings between a sphere and a disc and between a disc and a square, as well as combinations of both, are used in computer graphics applications, resulting in mappings between spheres and squares. Many options exist for each type of mapping; to pick the right methods for a given application requires knowledge about the nature and magnitude of mapping distortions.
This paper provides an overview of forward and inverse mappings between a unit sphere, a unit disc, and a unit square. Quality measurements relevant for computer graphics applications are derived from tools used in the field of map projection, and a comparative analysis of the mapping methods is given.
My CHI professor used to repeat that users didn’t read error messages, and that you should avoid them when possible. Think about it: how often do you close error messages without even reading whatever is written? And when you do read them, how often do you find them both clear and relevant?
