barycuda

Barycuda is a tiny CUDA accelerated library with no dependencies that performs various barycentric operations. This is an attempt to speed-up a 3D renderer that I'm working on.

Currently, the library exposes the following functions:

• point_in_simplex - takes an array of points, the vertices of a 2D/3D simplex, and tells you if each point lies inside the simplex.
• bary_simplex - takes an array of points, the vertices of a 2D/3D simplex, and returns the barycentric coordinates for each point.

Build

# inside the project directory
mkdir build
cd build
cmake ../
make

Usage

Please see src/testBary.cpp

Contributing

Feel free to add more geometric operations related to graphics rendering and raytracing.
