Installation

Requires VS2019+, Cuda 10.2+ and PyTorch 1.6+

Tested in Anaconda3 with Python 3.6 and PyTorch 1.8

One time setup (Windows)

Install the Cuda toolkit (required to build the PyTorch extensions). We support Cuda 10.2 and above. Pick the appropriate version of PyTorch compatible with the installed Cuda toolkit. Below is an example with Cuda 11.1

conda create -n dmodel python=3.6
activate dmodel
conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c conda-forge
conda install imageio
pip install PyOpenGL glfw

Install nvdiffrast: https://github.com/NVlabs/nvdiffrast in the dmodel conda env.

Every new command prompt

activate dmodel

Examples

Sphere to cow example:

python train.py --config configs/spot.json

The results will be stored in the out folder. The Spot model was created and released into the public domain by Keenan Crane.

Additional assets can be downloaded here [205MB]. Unzip and place the subfolders in the project data folder, e.g., data\skull. All assets are copyright of their respective authors, see included license files for further details.

Included examples

  • skull.json - Joint normal map and shape optimization on a skull
  • ewer.json - Ewer model from a reduced mesh as initial guess
  • gardenina.json - Aggregate geometry example
  • hibiscus.json - Aggregate geometry example
  • figure_brushed_gold_64.json - LOD example, trained against a supersampled reference
  • figure_displacement.json - Joint shape, normal map, and displacement map example

The json files that end in _paper.json are configs with the settings used for the results in the paper. They take longer and require a GPU with sufficient memory.

Server usage (through Docker)

  • Build docker image (run the command from the code root folder). docker build -f docker/Dockerfile -t diffmod:v1 . Requires a driver that supports Cuda 10.1 or newer.

  • Start an interactive docker container: docker run --gpus device=0 -it --rm -v /raid:/raid -it diffmod:v1 bash

  • Detached docker: docker run --gpus device=1 -d -v /raid:/raid -w=[path to the code] diffmod:v1 python train.py --config configs/spot.json

  • Proposition for more comprehensive Readme

    Proposition for more comprehensive Readme

    First of all, thank you for making this freely available for everyone! This is really a great move!

    I wanted to suggest a few things for the readme: 1.) Add "Microsoft Visual C++" to the requirements. It should be clear that you have to tick the C++ development environment while installing VS2019.

    2.) Install Git via "conda install git" (This makes it easier to install nvdiffrast and clone the repo)

    3.) Change "Install NVDiffRast" to something more descriptive: pip install -e git+https://github.com/NVlabs/[email protected]#egg=nvdiffrast

    4.) Add another step to the installation, detailing to move to a desired folder via the Anaconda Prompt and cloning this repo: cd YOUR/PATH/HERE git clone https://github.com/NVlabs/nvdiffmodeling.git and afterwards to move into the folder cd nvdiffmodeling

    5.) Installing CUDA via Anaconda only deploys the bare essential files. The CUDA path is not set when doing it this way. So I downloaded the CUDA toolkit from nvidia and installed it afterwards, to fix that.

    I am sure that all of these things are obvious for professionals, but it took me a while to figure all of this out, so I would like to save other people's time.

    About the raymarch fitting case

    Thanks for the marvelous work! I have some questions related to the shadertoy fitting case: It seems figure 22 & figure 23 use some special uv un-wrap methods, can you elaborate the algorithm under the hood? image

    RuntimeError: Error building extension 'renderutils_plugin'

    I am trying to get this to work to test the workflow but ran into the error I have installed "Cuda" 11.1 and everything else as in the tutorial Graphics accelerator 3080t

    After trying to run a test command, it gives me the following text Do you have any ideas how to fix this? I am more of a technical artist and a cursory search did not return much

    about effect Fig.22 and Fig 23

    I read your paper and video in detail，about LEARNING MESH AND MATERIALS FROM IMPLICIT SURFACES,How to improve the effect？ Can you give me some suggestions on setting super parameters? I used my own model as the target, started from the sphere you provided, and carried out experiments. I found that the feet and face were always unsatisfactory? There is a big gap with the rendering of snails and elephants mentioned in your paper. can you give me some adivce. image

    How to improve the optimization effect

    Your work is great. Thank you very much for your openness. I tried to use rendering on my own model, but I encountered the following problems and would like to consult: 1.In the process of rendering, I found that the face of the character, especially the eyes, was not poorly optimized, and the color could not be reflected. Are there any parameters that need to be adjusted? image 2.During rendering, I encountered that. mtl contains a map_ The texture of d cannot be represented in the renderer. How can I solve this problem? image

  • Lower training resolution => heavier texture pixelation. But why?

    Lower training resolution => heavier texture pixelation. But why?

    Hi, and thanks for great paper and comprehensive code! Could you please help me understand one thing:

    I'm running configs/dancer_displacement.json. Despite "texture_res" being 2048, these 2048 x 2048 textures "learn" huge pixels at lower "train_res":

    image

    And this isn't just poor interpolation in Blender, but these are actual large solid blocks (of different scale!) in normal_map_opt and kd_map_opt! Here is a part of texture_n.png from the top left experiment, 1:1 scale:

    image

    Why do these maps get more pixelated instead of getting more blurry? I've spent couple days searching the code for the source of this behaviour, and I believe there are only three relevant lines (for now let's consider texture only):

    Interpolation doesn't use 'nearest' method so it shouldn't be the source of big pixels. And because views are always different, rasterization should be a problem too. But probably I'm just missing some rendering subtleties?

    Thanks again!

    using camera calibration matrices

    Hi, first thanks for sharing this work! I'm trying to solve inverse rendering problem using a photogrammetry dataset which comes with accurate camera calibration mats. i have started from the spot example and i need to convert my intrinsic\extrinsic params to be used in the rastering and cant find an example or a guide to do it. the only hint is that I know it should be converted to openGL and NDC according to nvdiffrast, ill be happy to get an advice, thanks.

    some question about the complex material, such as that ray marching snail

    Hi, Thank you very much for your research. I'm trying to use your framework to approximate complex materials, but the blender complex material dataset I made with my own is not very good, because I encountered many problems with camera and light settings in my own rendering, Is the ray marching snail used in this paper directly rendered with shadertoy, or is the ray marching process written in Python?
