* Removed unnecessary evaluations while setting `sample_size` and `delta` properties.
3.7.0
* Added `delta_u` and `delta_v` properties to Surface classes. This change allows different sampling in u- and v-directions * Fixed some bugs related to `sample_size` property * Replaced `delta` with `sample_size` in Multi classes. `sample_size` property directly corresponds to `num` argument in [numpy.linspace](https://docs.scipy.org/doc/numpy/reference/generated/numpy.linspace.html) function.
These changes may cause a small API break in your existing code, especially if you are visualizing using the `geomdl.visualization.VisMPL` component. Please see the examples repository and check any example for the updated usage scenarios.
3.6.7
* Added `sample_size` property.
`sample_size` works very similar to `numpy.linspace`. In `numpy.linspace`, you define start and end positions with the number or samples to generate between them. This property automatically sets the `delta` property, so after setting `sample_size`, there is no need to play with `delta`.
3.6.6
* Bug fixes and compatibility updates * Added new tests
3.6.5
* Added Object File Format (OFF) export support to `exchange` module
