First use GPU-Voxels for collision detection #99

Hello, I want to use GPU-Voxels library to do collision detection of 3D models. I want to use two STL (STereoLithography) file format models for collision detection to find out if there is a collision between the two models and draw the Voxel of the model. What do I need functions to use at the beginning? Is there any example to know the building program? Thank you. My regular use environment is win10 and is developed in VS2013 using C++. I have successfully built the library using cmack.

Hi,

in order to make collision checks, you would need to voxelize your .stl mesh files. This can be done as described here: https://gpu-voxels.org/documentation/model-generation/

The script mentioned there will create .binvox files containing the voxels for a STL file.

As an example for collision detection you can look here: https://github.com/fzi-forschungszentrum-informatik/gpu-voxels/blob/master/packages/gpu_voxels/src/examples/Collisions.cpp

If your build was successful, you should find the binary for this example under build/bin/collisions.

I will close this issue as it is not about an error in GPU-Voxels. Feel free to reply here if there are further questions.
