CARL Volume Texture Synthesis

This project renders volumes from 2D textures using an optimized version of kopf 2007.

Installation

To install relevant packages, run the following:

pip install -r requirements.txt

Usage

Downloading Data

To download data, run the download_data.py as follows. The --obj parameter will pull from this repo.

python download_data.py --obj cow

Experiments

main.py runs the synthesis. texture defaults to tomatos and object defaults to a cube. You can visualize results with --show.

python main.py --texture-file [texture file] --object-file [obj file]

By default pyramid search is not used. If you want to half the resolution twice, pass in the downsampled resolutions at each level of optimization. Number of iterations is altered accordingly, so that the total number of iterations is 0.25 * num_iters + 0.5 * num_iters + 1 * num_iters.

python main.py --test-2d --resolutions 0.25 0.5 1 --num-iters 500 --no-show

The following code should generate a 2D zebra texture.

python main.py --test-2d --resolutions 0.5 1 --num-iters 800 --no-show

The following code should use deterministic sampling to generate a 2D zebra texture in around two minutes.

python main.py --num_iters 5 --resolutions 0.25 0.5 1 --no-show --test-2d --deterministic --shuffle-indices
