Download and Install:
Use pip to install:
pip install vtkplotter
Windows-10 users can place this file vtkplotter.bat on the desktop to drag&drop files to visualize. (Need to edit the path of the local Anaconda installation).

Intuitive and straightforward API which can be combined with VTK seamlessly in a program, whilst mantaining access to the full range of VTK native classes.
It includes a large set of working examples for all the following functionalities:
- Import meshes from VTK format, STL, Wavefront OBJ, 3DS, XML, Neutral, GMSH, OFF, PCD (PointCloud), volumetric TIFF stacks, DICOM, SLC, MHD, 2D images PNG, JPEG.
- Export meshes as ASCII or binary to VTK, STL, OBJ, PLY formats.
- Mesh analysis through the built-in methods of VTK package. Additional analysis tools like Moving Least Squares, mesh morphing.
- Tools to visualize and edit meshes (cutting a mesh with another mesh, slicing, normalizing, moving vertex positions, etc..). Interactive cutter widget.
- Split mesh based on surface connectivity. Extract the largest connected area.
- Calculate mass properties, like area, volume, center of mass, average size etc.
- Calculate vertex and face normals, curvatures, feature edges. Fill mesh holes.
- Subdivide faces of a mesh, increasing the number of vertex points. Mesh simplification.
- Coloring and thresholding of meshes based on associated scalar or vectorial data.
- Point-surface operations: find nearest points, determine if a point lies inside or outside a mesh.
- Create primitive objects like: spheres, arrows, cubes, torus, ellipsoids...
- Generate glyphs (associating a mesh to each vertex of a source mesh).
- Create animations easily by just defining the position of the displayed objects in the 3D scene. Add trailing lines and shadows to moving objects is also supported.
- Straightforward support for multiple sync-ed or independent renderers in the same window.
- Registration (alignment) of meshes with different techniques.
- Mesh smoothing with Laplacian and WindowedSinc algorithms.
- Delaunay triangulation in 2D and 3D.
- Generate meshes by joining nearby lines in space.
- Find the closest path from one point to another, travelling along the edges of a mesh.
- Find the intersection of a mesh with a line (or with another mesh).
- Analysis of Point Clouds:
- Moving Least Squares smoothing of 2D, 3D and 4D clouds
- Fit lines, planes and spheres and ellipses in space
- Identify outliers in a distribution of points
- Decimate a cloud to a uniform distribution.
- Basic histogramming and function plotting in 1D and 2D.
- Interpolate scalar and vectorial fields with Radial Basis Functions and Thin Plate Splines.
- Analysis of volumetric datasets:
- Isosurfacing of volumes
- Direct maximum projection rendering
- Generate volumetric signed-distance data from an input surface mesh
- Probe a volume with lines and planes
- Generate stream-lines and stream-tubes from vectorial fields
- Add sliders and buttons to interact with the scene and the individual objects.
- Fully customizable axis style.
latex-formatted formulas on the rending window.
- Examples using SHTools package for spherical harmonics expansion of a mesh shape.
- Integration with the Qt5 framework.
- Support for FEniCS/Dolfin platform for visualization of finite-element calculations.
- Visualization of tensors.
- Export a 3D scene and embed it into a web page.
- Embed the 3D rendering in a jupyter notebook with K3D (can export an interactive 3D-snapshot page here).
- Interoperability with the trimesh library.
Command Line Interface
Visualize a mesh from a terminal window with:
vtkplotter mesh.obj # valid formats: [vtk,vtu,vts,vtp,vtm,ply,obj,stl,3ds,dolfin-xml,neutral,gmsh, # pcd,xyz,txt,byu,tif,off,slc,vti,mhd,dcm,dem,nrrd,nii,bmp,png,jpg]
Voxel-data (mhd, vti, slc, tiff, dicom etc..) files can be visualized with options
vtkplotter -g examples/data/embryo.slc
To visualize multiple files or files time-sequences try
-s options. Use
-h for the complete list of options.
|Use a slider to control isosurfacing of a volume:||Load and browse a sequence of meshes:||Slice a 3D volume with a plane:||Visualize colorized voxels:|
