^*Corresponding Authors

In this work, we propose Interp3D, a training-free approach that instantiates the progressive alignment principle based on generative priors for textured 3D morphing. 

Installation

Clone the repo:

git clone --recurse-submodules https://github.com/xialul2/Interp3D.git
cd Interp3D

Following the command in TRELLIS for the environment installation.

Run the Code

You can run the morphing process with the following command:

python example_interp.py --exp_id ./web_cases

Interp3DData

To evaluate the effectiveness of our methods, we present Inter3DData, the benchmark dataset for assessing the generative texture 3D Morphing . You can download the dataset from Google Drive.
