![]() ![]() Kramer says that approach worked well, but it quickly became difficult to control the characters’ movements – even just small deformations proved distracting. That idea felt more analogous to a CRT that’s got a fixed number of pixels in space, and as the sprite moves underneath it those pixels are firing, lit up and colored by the sprite below.” Imageworks, for example, adopted a world space technique where, explains Kramer, “You basically have a static invisible field of voxels and as the character moves through the space the voxels are revealed where the two intersect. That’s more analogous to translating a 2D sprite sheet to 3D.”īoth Imageworks and Digital Domain would therefore model their respective characters as smooth digital forms with simple rigs and then pass them through a voxelization process in Houdini. It was like a sprite sheet for each pose – you may not have the exact same configuration of voxels. “The filmmakers liked the idea,” adds Kramer, “of rather than building the characters out of static voxels and animating them like a traditional character, they liked the idea that some of the voxels would appear and disappear. At the same time, if we needed more detail we’d look at the game art.” We still wanted ours to be 8-bit and low res. ![]() I feel that was the intention the game creators wanted their technology to be, but the technology couldn’t live up to creating that. “In the games there’s actually not a lot of detail, just a few pixels,” notes Imageworks visual effects supervisor Daniel Kramer, “so what gave us more inspiration was the artwork that’s on the game cabinets themselves. That’s where the filmmakers, and effects artists, immediately went for reference. Make the voxels A shot from the Centipede sequence.īased on Patrick Jean’s 2010 short film of the same name, Chris Columbus’ Pixels drew inspiration from 1980s arcade game characters. ![]() fxguide finds out how they overcame the voxel challenges. These were the issues faced by overall visual effects supervisor Matthew Butler and a host of VFX studios, lead by Digital Domain and Imageworks. How do you make and animate a voxelized character? How do they emit light? And how do you, as Earth fights back, destroy them? But that approach raised several questions. So instead they became voxels, able to exist in three-dimensional space. The characters, Pac-Man and Donkey Kong among them, had to inhabit the screen and be more than just 2D cut-outs. It may be called Pixels, but the first thing the visual effects team needed to do when creating a series of arcade game characters that attack Earth was…ignore the pixels. ![]()
