Tools

There are some helpful command line tools that are compiled alongside the main library. After installation the tools are globally available to be called.

rmagine_version

Prints the rmagine version. Should match the CMakeLists version.

user@pc:~/rmagine/build$ ./bin/rmagine_version
2.2.1

rmagine_benchmark

For every implemented computing device we compile a benchmark executable that simulates a Velodyne LiDAR sensor in a given mesh and prints out some useful run time statisitics. Thus, we can compare the run times of different implementations on several computers. The CPU / Embree version can be tested like this:

user@pc:~/rmagine/build$ ./bin/rmagine_benchmark_cpu ../dat/sphere.ply
Rmagine Benchmark CPU (Embree)
Inputs: 
- mesh: ../dat/sphere.ply
Unit: 1 Velodyne scan (velo) = 14400 Rays
- range of last ray: 0.998762
-- Starting Benchmark --
[ 129% - 2215.605926 velos/s, mean: 2387.607002 velos/s] 
Result: 2387.607002 velos/s

Analogously, the GPU benchmark can be started as follows:

user@pc:~/rmagine/build$ ./bin/rmagine_benchmark_gpu ../dat/sphere.ply
[RMagine - CudaContext] CUDA Driver Version / Runtime Version: 12.2.0 / 12.2.0
[RMagine - CudaContext] Construct context on device 0 - NVIDIA GeForce RTX 2060 
[RMagine - OptixContext] Init Optix (7.3.0). Required GPU driver >= 465.84
Rmagine Benchmark GPU (OptiX)
Inputs: 
- mesh: ../dat/sphere.ply
Unit: 1 Velodyne scan (velo) = 14400 Rays
Last Ray:
- range: 0.998762
-- Starting Benchmark --
[ 100% - 231941.938409 velos/s, mean: 231987.481164 velos/s] 
Result: 231987.481164 velos/s

rmagine_map_info

Prints useful information about the contents of a mesh file. Internally it is just printing the meta information of the assimp buffers.

user@pc:~/rmagine/build$ ./bin/rmagine_map_info ../dat/two_cubes.dae
