Least Squares Conformal Maps for Automatic Texture Atlas Generation

Implementation of the research paper Least squares conformal maps for automatic texture atlas generation

Requirements

Install libigl on the project folder, one directory above or in the other paths listed in cmake/FindLIBIGL.cmake

Install Eigen v3.3

<!-- ### Mac: ``` brew install eigen ``` ### Linux: ``` sudo apt-get install libeigen3-dev ``` -->

Compiling

mkdir build
cd build
cmake ..
make

Running

In build/ folder:

Default (Bunny Iso-(u,v) curves):

./lscm

Custom mesh and mode:

./lscm <path to .obj mesh> <mode>

.obj meshes:

• Fish: ../data/blub_triangulated.obj
• Bunny: ../data/LSCM_bunny.obj
• Pumpkin: ../data/pumpkin_tall_10k.obj
• Cow: ../data/spot_triangulated.obj
• Teddy: ../data/teddy.obj

modes:

• 0 : show initial features
• 1 : show feature curves
• 2 : show charts
• 3 : show iso-(u,v) curves
• 4 : show packing

examples:

./lscm ../data/blub_triangulated.obj 0
./lscm ../data/LSCM_bunny.obj 1
./lscm ../data/pumpkin_tall_10k.obj 2
./lscm ../data/spot_triangulated.obj 3
./lscm ../data/teddy.obj 4
