A path through a forest, rendered entirely with my hobby renderer, Takua Renderer. More info is available on my project pages and blog.
Hello, I'm Karl (or, in Chinese: 黎忆宁)!
Born in Hannover, Germany and raised in Philadelphia, Pennsylvania, I am a staff software engineer at Walt Disney Animation Studios working on Disney's Hyperion Renderer. As part of the Hyperion team, I've worked on every Disney Animation theatrical release starting from Zootopia. I work and happily live in Burbank, California with my wife, Harmony M. Li, and our family.
My areas of interest cover all things production rendering, including topics such as advanced light transport, renderer architectures, raytracing on interesting hardware, volume rendering, surface appearance, and more.
