latent-paint-mesh's Introduction

Latent-Paint-Mesh

NVDiffrast based implementation of Latent-Paint from Latent-NeRF

Use text to edit textures of a 3D model or create new ones - powered by Stable Diffusion

Creating texture with prompt "Goldfish"

Editing an existing texture with prompt "Air Jordan 1"

Quickstart

Use the following Google Colab notebook to get started - creating a texture map for 3d car model using text prompt "Lightning McQueen" (~5 mins)

Setup

git clone https://github.com/NasirKhalid24/Latent-Paint-Mesh.git
cd Latent-Paint-Mesh
pip install -r requirements.txt

Usage

python main.py --mesh data/blub/blub_triangulated.obj --text "Goldfish" --epochs 2500 --log 250

  optional arguments:
  --gpu GPU            GPU index (default 0)
  --mesh MESH          Path to .obj must have uv unwrapped
  --material MATERIAL  Path to starting material, if none will randomly initialize
  --text TEXT          Text prompt
  --lr LR              Learning rate
  --scale SCALE        Factor by which to scale up 64x64 texture map (default 2)
  --log LOG            Log every x epochs, set to -1 to disable logging (much faster)
  --dist_min DIST_MIN  Minimum camera distance
  --dist_max DIST_MAX  Maximum camera distance
  --azim_min AZIM_MIN  Minimum camera azimuth in degrees
  --azim_max AZIM_MAX  Maximum camera azimuth in degrees
  --elev_min ELEV_MIN  Minimum camera elevation in degrees wrt x plane (use -x and +x for elevation)
  --elev_max ELEV_MAX  Maximum camera elevation in degrees wrt x plane (use -x and +x for elevation)
  --fov_min FOV_MIN    Minimum FOV in degrees
  --fov_max FOV_MAX    Maximum FOV in degrees
  --offset             Offset mesh from center
  --colab              Enable for google colab logging
  --prompt_aug         Prompt augmentatio (side, back)
  --auto_cam           Automatically calculate camera params
  --epochs EPOCHS      How many iterations to run for
  --guidance GUIDANCE  Guidance scale for cfg (0 to 1)
