New Features Add full support for widgets in the rendering scene! (See #360) Box widget - Create a box in 3D space. Includes a convenience method for clipping meshes Plane widget - Create an implicit plane in 3D space. Includes a convenience method for clipping and slicing meshes Slider widget - Add a slider bar to the render window. Includes a convenience method for thresholding meshes Line widget - Create and orient a line in 3D space. Point picking (see #362) Single point picking on meshes and in 3D space Trace lines across meshes using a geodesic path Trace lines through a scene by picking points on meshes or in 3D space Trace out horizon surfaces Wrap the vtkTable class (see #274 and the new pyvista.Table class) Add a structured grid cylinder helper method (see pyvista.CylinderStructured) which works creates a pyvista.StructuredGrid mesh in the shape of a cylinder. New .ribbon() filter for PolyData objects - create surfaces ("ribbons") from lines interpolate_befor_map is now set too True as default (see #363 and this example for details) Bug Fixes Resolve issues with the lines_from_points helper methods (see #357) Fix an issue when fetching null points on datasets
