Voxcube is a small program for rendering density maps. Density maps
are just raw files containing density samples (unsigned integer
values, one or more bytes per sample) on a Cartesian grid which covers
a unit cube. Samples are encoded in a sequential slice-by-slice
order. Bigger values of a sample designate more opaque material at
that point and smaller values designate more transparent
material. There must be a small JSON file with information about size
of a density map on each dimension, possibly the size of a sample in
bytes (default is 1 byte per sample) and the name of a density map to
run the program. See examples for more info.
- CMake for building.
- OpenGL
- GLM
- json-cpp
Run the following commands from this directory (this will do system-wide installation of voxcube):
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RELEASE ..
make
make install # Root required
If you do not want to install voxcube system-wide, you can do the following:
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RELEASE -DSYSTEM_WIDE=OFF ..
make
and run voxcube binary from the directory which contains shaders/
subdirectory.
Running voxcube is straightforward: voxcube -c cfg.json where
cfg.json is a configuration file which describes your density map.
WASDmove the camera.- Rotate the camera with mouse.
Pincrease density threshold (just press it one or two times to see what it means).Odescrease density threshold.
examples/ directory contains some density maps and configuration
files to play with. For example, try
voxcube -c /path/to/examples/bonsai.json.
All examples were taken from open sources on the net long time ago. I do not even remember from where and I cannot credit the authors. If you are holding the rights for them and want to be credited for your work, please open an issue. Also I can remove these examples if you do not want me to share them.
