Demo

Installation

The demo requires building a PyTorch extension. If you have a sane development environment with PyTorch, g++ and nvcc, you can simply

pip install git+https://github.com/CompVis/geometry-free-view-synthesis#egg=geometry-free-view-synthesis

If you run into problems and have a GPU with compute capability below 8, you can also use the provided conda environment:

git clone https://github.com/CompVis/geometry-free-view-synthesis
conda env create -f geometry-free-view-synthesis/environment.yaml
conda activate geofree
pip install geometry-free-view-synthesis/

Running

After installation, running

braindance.py

will start the demo on a sample scene. Explore the scene interactively using the WASD keys to move and arrow keys to look around. Once positioned, hit the space bar to render the novel view with GeoGPT.

You can move again with WASD keys. Mouse control can be activated with the m key. Run braindance.py <folder to select image from/path to image> to run the demo on your own images. By default, it uses the re-impl-nodepth (trained on RealEstate without explicit transformation and no depth input) which can be changed with the --model flag. The corresponding checkpoints will be downloaded the first time they are required. Specify an output path using --video path/to/vid.mp4 to record a video.

> braindance.py -h
usage: braindance.py [-h] [--model {re_impl_nodepth,re_impl_depth}] [--video [VIDEO]] [path]

What's up, BD-maniacs?
