Mesh and Point Cloud Viewer

Building

On Ubuntu system, the following packages are required:

  • cmake
  • qt5-default
  • libtbb-dev
  • libxerces-c-dev

Additional optional dependencies are:

  • libjpeg-dev - needed for loading large jpeg textures (Qt can only handle up to 32767x32767)
  • libpng-dev - needed for loading large png textures
  • libgdal-dev - needed for loading GeoTIFFs as mesh

First, clone the repository and create a build directory using:

git clone --recursive https://github.com/pavelsevecek/mpcv.git
cd mpcv
mkdir build
cd build

Then, configure mpcv using cmake (use OFF if you did not install the optional libraries) and build it

cmake -DCMAKE_BUILD_TYPE=Release -DWITH_PNG=OFF -DWITH_JPEG=OFF -DWITH_GDAL=ON ..
make
