Below we present the MATLAB scripts that were used in [1] for the preparation of the reference models and the generation of rendering-related meta-data:

- *fun_voxelize*: Used to voxelize point clouds in order to produce the reference models. Check ../contents/README.txt to identify which point clouds were voxelized using this script.
- *fun_pointsize*: Used to estimate the size of each point for every stimulus, using adaptive rendering mode with 12 nearest neighbours. For a given stimulus, the output of the script was stored in a JSON file, and the latter was imported as meta-data to our renderer [2].

For more details, please refer to [1].
