Scroll Renderer

Scroll Renderer is a Python package developed by the Vesuvius Challenge Team 2024. It provides tools for flattening and rendering 3D meshes of segments of the Herculaneum Papyri. It is currently in alpha version.

Requirements

• Python 3.11 (no newer versions are currently supported)
• CUDA 12+ installed on the machine

It is recommended to run this package in a Conda environment to manage dependencies effectively.

Installation

1. Clone the repository and navigate to the project directory:

   git clone https://github.com/your-repo/scroll_renderer.git
   cd scroll_renderer

2. Install the package in editable mode:

   pip install -e .

Commands

The package provides command-line utilities for working with mesh files. For more options and details on each command, you can use the --help option after any command.

Example Usage

1. Flatten a Mesh

   Use the slim_uv command to flatten a mesh with the following options:

   slim_uv --path 20241025062044_intermediate_mesh.obj --ic harmonic --iter 200

   • --path: Path to the intermediate mesh file (e.g., .obj file).
   • --ic: Initial condition; options are harmonic or arap.
   • --iter: Number of iterations.

2. Render a Flattened Mesh

   After flattening, use mesh_to_surface to generate a surface render of the mesh:

   mesh_to_surface 20241025062044_intermediate_mesh_flatboi.obj /mnt/localdisk/scrolls/Scroll5 --r 32

   • First argument: Path to the flattened mesh file.
   • Second argument: Scroll volume, can be zarr, tifstack or grid cells.
   • --r: Half number of layers in the surface volume besides the center (e.g., 32 will give 65 layers, the middle +- 32).
   • --triangle_batch: Choose how many triangles to process per batch, default 5000
   • --max_side_triangle: Choose the max length of the side of a triangle when creating dataset, default 10
   • --nr_workers: Choose nr workers to load the dataset
   • --prefetch_factor: Choose the prefetch factor, default 2

For additional options and usage information, use --help with any command (e.g., slim_uv --help or mesh_to_surface --help).
