threestudio-lrm

The threestudio-lrm is an extension for threestudio, integrating the Large Reconstruction Model (LRM) for advanced 3D reconstruction tasks. This model is based on the framework detailed at https://yiconghong.me/LRM/. We have adapted the open-source implementation from OpenLRM. Currently, it is only used for initialization of Gaussian Splatting.

Installation

cd custom
git clone https://github.com/Adamdad/threestudio-lrm

# install openLRM
cd threestudio-lrm
git clone https://github.com/3DTopia/OpenLRM.git
cd OpenLRM
pip install -r requirements.txt

Examples

Please see threestudio-3dgs for more details.

Supported Modes

The threestudio-lrm currently supports two modes:

  1. Text-to-Image Mode (text2image):

    • Generates a single image from a text prompt using SDXL.
    • Transforms the image into a triplanar representation, then to a mesh, and finally to a point cloud using LRM.
    • Initialize the 3DGS

  2. Image-to-Image Mode (image2image):

    • Directly loads a single-view image.
    • Generates a point cloud from this image.
    • Initialize the 3DGS
