GBS is header library for computing bspline curves and surfaces.
GBS is compatible with OpenCASCADE, curves and surfaces can be converted to OpenCASCADE's objects.
Example of point cloud approximation:
Example of points surface interpolation:
Example of curve-surface intersection:
Example of loft-surface creation:
Example of surface approximation of points:
Example of curve 2d variable offset:
Example of curve on surface:
Example of python code to interpolate points
pts= [ [0.,0.,0], [0.,0.,1], [1.,0.,0.5], [1.,1.,1] ]constraints= []forpinpts:constraints.append([p])degree=2crv=gbs.interpolate_cn_3d_d(constraints,degree,gbs.KnotsCalcMode.CHORD_LENGTH )
For now, this lib is to be used inside a conda environment with the following package installed:
The optional module gbs-occt requires the additional package:
The optional module render requires the additional package:
The python bindings requires the additional package:
The test library needs:
For efficient buid use:
rattler-build build --recipe .\gbs\recipe\recipe.yaml -c ssg-aero -c conda-forge
Warning tests relative to performances evaluation should be run in release mode
As GBS base is a header library it doesn’t need compilation.
If one needs to compile the optional module gbs-occt, -DUSE_OCCT_UTILS:BOOL=TRUE shall be added to cmake command.If one needs to compile the optional module render, -DUSE_RENDER:BOOL=TRUE shall be added to cmake command.If one needs to compile the optional module python-bindings, -DUSE_PYTHON_BINDINGS=TRUE shall be added to cmake command.
The full test suite, which require the optional module gbs-occt, please add -DGBS_BUILD_TESTS:BOOL=TRUE to the cmake command.
