Path tracer with triangle primitives and binary space partitioning

UPDATE: The post below was a purely naive attempt at implementing a rudimentary bounding volume hierarchy. A much more efficient implementation using a kd tree is available in this post. We will continue with the project we left off with in this post. We will attempt to add triangles to our list of primitives. Once we are able to render triangles, this opens the door to rendering full scale models. However, because models will contain upwards of thousands of triangles, we need to be able to Read more [...]

A basic path tracer with CUDA

The path tracer we will create in this project will run on CUDA-enabled GPUs. You will need to install the CUDA Toolkit available from NVIDIA. The device code for this project uses classes and must be compiled with compute capability 2.0. If you are unsure what compute capability your card has, check out this list. Below are two screen captures of this project in action. This path tracer is basic and fairly crude and inefficient. I'll provide a brief overview of the code before Read more [...]
