# Render COLMAP reconstructed Model with Pytorch3D

## Dependencies

- PyTorch

- PyTorch3D

- opencv-python

- pillow

- IPython

## Data

### Real Data

```

data_colmap/

├── images/

    └── *.jpg

├── meshed-delaunay.obj

└── sparse

    ├── cameras.bin

    ├── images.bin

    └── points3D.bin

The `sparse/` and `images/` are from the dense reconstruction stage of colmap.

### Synthetic Data

The synthetic cow model used in the pytorch3d document.



     



## Get Started

```

# Render depth and normal map of a reconstructed mesh using a colmap camera

python render_colmap_mesh.py

```

```

# Render a simple cow mesh

python render_colmap_mesh.py --debug

```
