VISIUM
VISIUM is a powerful 3D visualization and data analysis application designed for geophysical modeling and inversion workflows. VISIUM provides comprehensive tools for:
Data Import & Model Management
- Loads common grid, point-cloud, surface, and volumetric data formats
- Tree-based model browser for organizing datasets and their derived results
- Colour any model by its data attributes, with automatic colour scales
Visualization
- Real-time 3D rendering with surface, wireframe, points, and surface-with-edges display modes
- Customizable colour maps, opacity, lighting/materials, and per-model styling
- Configurable colour scale bars (size, position, ticks) and axes grid
- Dual-view mode for side-by-side comparison
- On-screen text annotations with full rich-text formatting (fonts, colours, styles, alignment, bordered boxes)
Analysis Tools
- 2D and 3D data plotting
- Vector/arrow plotting
- Contour lines and iso-surfaces (contour volumes)
- Distance measurement
- Clipping, slicing (regular & irregular), and thresholding filters
- Colour smoothing and gridding utilities
Surface Creation & Reconstruction
- Delaunay 2D — build surfaces from point sets on any plane (including vertical/tilted), with optional interior-point insertion for high-quality triangles
- Boolean operations — union, intersection, and difference between surfaces, with standard and robust engines
- Make Geometry — create parametric source geometries
Surface Remeshing
- Mesh simplification (quality-preserving and fast clustering methods)
- Uniform and adaptive remeshing to a target edge size
- Decimation by reduction percentage or distance
- Triangulation, hole filling, and vertex merging
Interactive Mesh Editing (Manipulate Elements)
- Delete triangles or points (with optional surface-preserving hole repair)
- Generate new triangles by picking vertices
- Fill Hole — manually or auto-detect holes and fill them, with quality options
- Move Point / Move Triangle — reposition elements numerically or by dragging, with adjustable soft-influence on surrounding cells
- Full undo/redo
Output
- High-resolution screenshots with supersampling, region capture, and adjustable dimensions/DPI
- Export to standard data formats for use in downstream workflows
