Abstract: Text-to-3D synthesis has recently emerged as a new approach to sampling 3D models by adopting pretrained text-to-image models as guiding visual priors. An intriguing but underexplored problem with existing text-to-3D methods is that 3D models obtained from the sampling-by-optimization procedure tend to have mode collapses, and hence poor diversity in their results. In this paper, we provide an analysis and identify potential causes of such a limited diversity, which motivates us to devise a new method that considers the joint generation of different 3D models from the same text prompt. We propose to use augmented text prompts via textual inversion of reference images to diversify the joint generation. We show that our method leads to improved diversity in text-to-3D synthesis qualitatively and quantitatively.
Details of the model architecture and experimental results can be found in our paper:

The following steps have been tested on Ubuntu20.04.
- You must have an NVIDIA graphics card with at least 6GB VRAM and have CUDA installed.
- Install
Python >= 3.8. - (Optional, Recommended) Create a virtual environment:
python3 -m virtualenv venv
. venv/bin/activate
# Newer pip versions, e.g. pip-23.x, can be much faster than old versions, e.g. pip-20.x.
# For instance, it caches the wheels of git packages to avoid unnecessarily rebuilding them later.
python3 -m pip install --upgrade pip- Install
PyTorch >= 1.12. We have tested ontorch1.12.1+cu113andtorch2.0.0+cu118, but other versions should also work fine.
# torch1.12.1+cu113
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 --extra-index-url https://download.pytorch.org/whl/cu113
# or torch2.0.0+cu118
pip install torch torchvision --index-url https://download.pytorch.org/whl/cu118- (Optional, Recommended) Install ninja to speed up the compilation of CUDA extensions:
pip install ninja- Install dependencies:
pip install -r requirements.txt- (Optional)
tiny-cuda-nninstallation might require downgrading pip to 23.0.1
