Kit-CAE 3.0#

Kit-CAE is a reference application for composing, exploring, and visualizing engineering data with OpenUSD. It reads native scientific formats on demand and provides GPU-accelerated operators for surfaces, points, glyphs, streamlines, volumes, slices, and iso-surfaces.

How This Guide Is Organized#

The main guide uses one vehicle-aerodynamics dataset. Its Try It sections build on one another, so start with Get Started and continue in this order:

  1. Import Data

  2. Explore Your Data

  3. Create Sources

  4. Create Operators

  5. Color Mapping and Rendering

  6. Flow Visualization

The Examples are self-contained:

What’s New in 3.0#

Important

Field discovery and assignment changed in 3.0. Imported fields no longer appear as child prims in the Stage panel. Select the relevant OmniSciDataset or field-owning prim, then use Arrays and Array Details in the Properties panel to discover and inspect its fields. The new representation keeps the Stage hierarchy compact and lets you inspect field metadata in one place. Field values remain on demand and load only when requested by a visualization or Array Details.

Operators no longer use Add Target for field inputs. Use Add Field to assign one or more fields for coloring, streamlines, Flow, and other field-driven operations. Add Target remains for dataset relationships such as Seeds and regions of interest.

Visualization

  • Iso Surface: Extract a triangular surface at a selected scalar value from point- or cell-associated fields.

  • Planar Slices: Extract one or more geometry-based slices directly from source data without first creating a Volume with NVIDIA IndeX.

  • Field-driven opacity: Map opacity independently from color on Faces, Points, Glyphs, Iso Surfaces, Streamlines, and Planar Slices.

  • Colormap sources: Create reusable color and opacity ramps directly in the stage.

Data and exploration

  • New native formats: The standard app now reads EDEM, Eclipse reservoir, and NanoVDB files.

  • Standard VTK import: Open VTK files in the standard application. Normal imports no longer require the VTK application variant.

  • Array Details: Inspect association and time samples from field-owning prims, alongside existing shape, range, statistics, and histogram views. Detailed statistics are computed on demand from the Properties panel.

Workflow

  • Long-running visualization operators report progress in the status line.

  • Moving a region-of-interest source automatically updates dependent operators.
