  • sphere_cell_collision_serial(): Generates a sphere and detects cell collisions in serial. Where each cell is checked one by one
  • sphere_cell_collision_minibatch(): Generates a sphere and detects cell collisions in minibatch. Where groups/minibatches of cells are checked

Installation Guide

1. On the Host Machine. Place RayBNN.zip into $RAYBNN_DIR and unzip it.

Set the $RAYBNN_DIR enviromental variable to a folder that will store all the RayBNN files

For example, setting $RAYBNN_DIR to /opt/

export RAYBNN_DIR=/opt/

Place RayBNN.zip into $RAYBNN_DIR and unzip it to produce:

  • $RAYBNN_DIR/RayBNN/src/

  • $RAYBNN_DIR/RayBNN/examples/

  • $RAYBNN_DIR/RayBNN/matlab_plot/

  • $RAYBNN_DIR/RayBNN/python_verify/

2. Make Sure Matlab is Installed On the Host Machine.

Make sure Matlab is installed on the host system. Tested on Matlab 2023a

3. On the Host Machine. Download CUDA Docker Container from Nvidia
