cd O-CNN/virtual_scanner/
.
This folder contains the code for converting 3D models to dense point clouds with normals. It outputs a mesh in the PLY
format.
Install
apt-get install -y --no-install-recommends libboost-all-dev libcgal-dev libeigen3-dev
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
Usage
VirtualScanner <file_name> [nviews] [flags] [normalize]
file_name: the name of the file (*.obj; *.off) to be processed.
nviews: the number of views for scanning. Default: 6
flags: Indicate whether to output normal flipping flag. Default: 0
normalize: Indicate whether to normalize input mesh. Default: 0
Example:
VirtualScanner input.obj 30 // process the file input.obj
Easily convert ply to obj
apt-get install assimp-utils
assimp export test.ply test.obj
Shuffle points sampled from Virtual Scanner. Can be useful to quickly load a subsampled version on the pointcloud (just read a random block of lines in a PLY).
Dependencies : pip install argparse joblib
and install Pymesh
