vedo 2021.0.2 A new web page is avaialble! check it out at https://vedo.embl.es python2 is no more supported A dangerous bug in mesh.closestPoint(returnIds=True) has been fixed Added interfaces and examples to libraries iminuit and pymeshlab variable datadir changed to dataurl added ipyvtk_simple option for notebooks rendering base.py method addPos() (obsolete but still valid) renamed to shift() added shortcut to input the opacity with syntax mesh.color("blue", 0.5) arrays with name "Normals" are set as active normals automatically ( @theponpon ) added keyword invert in getTransform() ( @Tai-Hsien ) added deleteCells() method addons.py added mesh cutter with planes and spheres in addition to boxes ( @nantille ) major revision of the Axes class. with new added feature like axes inversion, free rotations keyword xFlipText disappeared as is now substituted by xLabelRotation Added xyShift to shift the whole cartesian plane along one axis ( @JGarrett7 ) Axes can be flipped with their range with xInverted (caveat: this does not at all affect the world coordinate system!) new class LegendBox to show a legend with icons colors.py vedo is now independent of matplotlib for colormaps added new bootstrap5 color scheme (e.g. c='red1', 'red2', ..., 'red9', or in short: c='r1', 'r2', ..., 'r9') Lower index means darker. added rgb2hex() and hex2rgb() functions fixed bug on printc() and added settings.enablePrintColor. #337 mesh.py fixed bug in splitByConnectivity() ( @jsanchez679 ) added method addConnectivity() to add a connectivity array to mesh points added method isClosed() ti return if mesh is watertight (no holes) plotter.py improved resetcam behaviour passing camera no more empties the passed dictionary (thanks @icemtel ) verbose keyword has been removed (as hard to maintain) mouse clicking can now pick Picture not only Mesh revised and improved callback functionality with plotter.addCallback() (see examples mousehighlight, mousehover) new way of creating a callback loop with a timer (thanks @nantille - see examples timer_callback) picture.py attribute picture.shape holds the shape of the picture in pixels added gif file reader to return a list of Picture objs. added clone() method. pointcloud.py added fitCircle() to fit a circle to a line in 3D. added a revision of self.densify(). Removed densifyCloud(). #338 pyplot.py a brand new function fit() to perform polynomial fitting to data with error bars in both x and y with correct estimation of error bands via bootstrap method (there are out there soo many wrong scripts in matplotlib!) added pyplot.matrix() to plot numpy matrices (eg. correlation/covariance matrix) various minor fixes shapes.py Spline can control the easing, the density of points along the line. support for closed splines. Text2D completely rewritten. Can now update it after creation (e.g. mytxt.text("test").color("g")) volume.py added volume.shade() which can be True or False. Disable by default (was previously enabled) to be used in conjunction with volume.lighting() to create a mesh-like rendering of the volume. (thanks to @nantille for debugging) fixed example interpolateVolume (thanks @rafaelmarch3 ) New/Revised examples: vedo -r colorcubes vedo -r cutter vedo -r spline_ease vedo -r gyroid vedo -r align6 vedo -r colormap_list vedo -r bloch vedo -r slicePlane1 vedo -r slicePlane2 vedo -r pygmsh_cut vedo -r mousehighlight vedo -r mousehover vedo -r line2mesh_quads vedo -r line2mesh_tri vedo -r pointsCutMesh2 vedo -r hoverLegend vedo -r iminuit vedo -r pymeshlab1 vedo -r timer_callback1 vedo -r timer_callback2 vedo -r fitCircle vedo -r anim_lines vedo -r earthquake_browser vedo -r np_matrix vedo -r customAxes2 vedo -r customAxes3 vedo -r glyphs3 vedo -r fitPolynomial1 vedo -r fitPolynomial2 vedo -r histo_gauss vedo -r plot_polar vedo -r densifycloud vedo -r interpolateVolume
