ziran2020's Introduction

Code description

This is the opensource code for the following papers:

(1) AnisoMPM: Animating Anisotropic Damage Mechanics, Joshuah Wolper, Yunuo Chen, Minchen Li, Yu Fang, Ziyin Qu, Jiecong Lu, Meggie Cheng, Chenfanfu Jiang (SIGGRAPH 2020) Project Page: https://joshuahwolper.com/anisompm

(2) IQ-MPM: An Interface Quadrature Material Point Method for Non-sticky Strongly Two-way Coupled Nonlinear Solids and Fluids, Yu Fang*, Ziyin Qu* (equal contributions), Minchen Li, Xinxin Zhang, Yixin Zhu, Mridul Aanjaneya, Chenfanfu Jiang (SIGGRAPH 2020)

Troubleshooting Compiling

If anyone encounters compiling errors with GNU 9.3.0 or other versions, please switch to GNU 7.5.0 to compile which we've verified to work.

Use the following command to install GNU 7.5.0.

sudo apt-get install g++-7

When executing cmake, users should manually choose the compiler to use as well.

cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/bin/gcc-7 -DCMAKE_CXX_COMPILER=/usr/bin/g++-7

Unzip Data

Download and unzip the following file in the root directory.

https://drive.google.com/file/d/1f22ObJmiq8H1_YObTz5BuE4IAWLQhyuB/view?usp=sharing

You need to do this due to the github single file size limit.

Dependencies Installation

sudo apt-get install make cmake g++ libeigen3-dev gfortran libmetis-dev
sudo apt-get install libopenvdb-dev libboost-all-dev libilmbase-dev libopenexr-dev
sudo apt-get install libtbb2 libtbb-dev libz-dev clang-format-6.0 clang-format

Building in Ziran

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j 4

Running Demos

Check folder Projects/anisofracture for AnisoMPM
Check folder Projects/coupling for IQ-MPM

Sampling Particles

We used TetWild to compute tetrahedralized volumes to sample particles from, check it out here: https://github.com/Yixin-Hu/TetWild

Visualization

We dump out .bgeo files for visualization and use Houdini to visualize our outputs. For converting a point cloud to a surface we use the meshing algorithm seen here: https://dl.acm.org/doi/10.1145/3340259, but you also have the option to use Houdini's VDB support to directly compute a VDB level set surface from the output particles (see https://www.sidefx.com/docs/houdini/nodes/sop/vdbfromparticles.html)

Data.zip is missing

The Data.zip file referred to in the readme is missing.

Could you please give a sample Houdini render scene file for reference?

Thank you very much!

Link error: Undefined symbols for architecture x86_64: "openvdb::v7_2::io::..."

I followed the guidance to turn off the amgcl CUDA:
option(ENABLE_AMGCL_CUDA "Use amgcl cuda" OFF)
But now I am configured successful but failed in generate, the CMake info as follows:
