Back in 2016, I took part in a large open-source program called Google Summer of Code or GSoC. Specifically, I worked with an organization called BRL-CAD which specialised in a computer-aided design (CAD) software. Here is the official project page from GSoC archives.

Rendering primitives

For my GSoC project, I proposed to improve OpenCL support for the BRL-CAD raytracer. I successfully accelerated the rendering of a few primitive shapes such as EPA (elliptical parabolloid), ETO (elliptical torus), PART (lozenge shaped object).

Rendering more complex objects

Subsequently, I reimplemented a boolean weaving algortihm to combine multiple primitives to yield more complex shapes. Boolean operations include Union, Intersection and Difference.

Denoising diffusion probabilistic models

The majority of deep generative models proposed in the last few years have broadly fallen under three categories—generative adversarial networks (GANs), variational autoencoders (VAEs), and normalizing flows. There are few others, such as autoregressive models and those based on transformers, but they are much slower to sample. As a result, they are not widely used, particularly when the distribution being modeled is very high-dimensional.
