LogInMatt Estela showcased the results of his latest experiment achieved with new COPs.
Earlier this year, SideFX released Houdini 20.5, unveiling a range of new workflows, features, and enhancements, including Copernicus, the new COPs context in Houdini. What you see above is a real-time Las Vegas Sphere-style visualization created using new COPs by Matt Estela, the creator of CG Wiki, a resource filled with valuable tips and tricks to help you sharpen your Houdini skills.
According to him, this prototype took just 40 minutes and could have been done with older COPs, but it'd have been slower and unreliable. The setup is highly configurable, in this example, rays are traced from the surface of a sphere back toward the origin.
"The core idea is relatively simple: steal some spherical projection code from the original Mantra ASAD lens shader and use it to drive a vex intersect call. Do some cheaty lookups for color, fake a lighting pass, done.
The actual visualization takes advantage of how fast new COPs work with the rest of Houdini; the texture is fed to a uvquickshade node running on another sphere. Super fun stuff."
