Features
Vedo stands out for its comprehensive suite of features that encompass working with various types of 3D data structures:
Polygonal Meshes and Point Clouds
- Import and export meshes in multiple formats like VTK, STL, OBJ, and PLY.
- Perform operations like cutting, slicing, mesh smoothing, and morphing.
- Create and customize basic 3D shapes such as spheres and cubes.
- Analyze structures by calculating areas, volumes, and curvatures.
- Find nearest points, fill mesh holes, and determine if points lie inside meshes.
Volumetric Data and Tetrahedral Meshes
- Import data from formats like TIFF stacks, DICOM, and MHD.
- Execute isosurfacing, volumetric rendering, and slicing operations.
- Visualize data with enhanced techniques like stream-lines from vector fields.
2D and 3D Plotting and Histogramming
- Render 3D text with LaTeX-like syntax and symbolize mathematical formulas.
- Generate pie charts, scatter plots, and surface functions in 2D and 3D.
- Utilize various plot types such as polar plots, violin plots, and histograms.
