**NVIDIA Omniverse** is showcasing a demo application that utilizes **CurvSurf FindSurface** technology. Here are the key features:

- Users can upload point clouds stored on their computers directly into the Omniverse App.
- _FindSurface_ processes raw point clouds in real-time, achieving speeds of 2-10ms per _USD Prim_ without the need for pre-processing.
- As users move their mouse within the viewport, FindSurface extracts the object surface at that location, creating _USD Prims_ (such as planes, spheres, cylinders, cones, and tori) rendered in _preview mode_ in real-time.
- The mouse can also function as a point cloud eraser, making inlier points invisible.
- A mouse-click captures the current preview _USD Prim_ and places it in the viewport, allowing users to adjust FindSurface parameters with a slider-bar. The updates to the _USD Prim_ occur in real-time, accompanied by an error-heatmap animation.
- A custom extension wraps CurvSurf’s proprietary FindSurface binary ( **300KB** ), enabling a variety of domain-specific applications.
- This demo app illustrates how to effectively use the FindSurface Extension within an Omniverse application.
- Real applications may receive point clouds _online_.
- The source code for the app will be publicly available on GitHub CurvSurf under the MIT License by the **end of June 2026**.
