MODELING SYSTEM FOR 3D VIRTUAL MODEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240020935 titled 'MODELING SYSTEM FOR 3D VIRTUAL MODEL

Simplified Explanation

The abstract describes a modeling system that retrieves a 3D virtual model of an object from non-volatile memory. It then defines a domain of a parametric surface and projects feature curves from the 3D virtual model into the domain to generate a mapping. The mapping includes multiple parametric curves, which are divided into horizontal and vertical feature curves. The system extends these curves and constructs horizontal and vertical interpolants to connect them. It fits these interpolants as coordinates of a map to a new parametric domain and composes the inverse of the map with the parametric surface to create a new parametric surface containing the feature curves as isoparametric curves.

• The system retrieves a 3D virtual model of an object from memory.
• It defines a domain of a parametric surface.
• Feature curves from the 3D virtual model are projected into the parametric surface's domain to create a mapping.
• The mapping includes multiple parametric curves.
• The parametric curves are divided into horizontal and vertical feature curves.
• Each feature curve is extended.
• Horizontal and vertical interpolants are constructed to connect the extended feature curves.
• The interpolants are fitted as coordinates of a map to a new parametric domain.
• The inverse of the map is composed with the parametric surface to create a new parametric surface.
• The new parametric surface contains the feature curves as isoparametric curves.

Potential applications of this technology:

• Computer-aided design (CAD) software for creating and manipulating 3D models.
• Virtual reality (VR) and augmented reality (AR) applications for immersive experiences.
• Industrial design and product development for prototyping and visualization.
• Medical imaging and surgical planning for accurate representations of anatomical structures.

Problems solved by this technology:

• Efficient retrieval and manipulation of 3D virtual models.
• Accurate projection and mapping of feature curves onto parametric surfaces.
• Seamless integration of feature curves into new parametric surfaces.
• Improved visualization and representation of complex objects.

Benefits of this technology:

• Enhanced precision and accuracy in modeling and design processes.
• Increased efficiency in creating and modifying 3D models.
• Improved realism and fidelity in virtual and augmented reality experiences.
• Facilitates better understanding and analysis of complex objects and structures.

Original Abstract Submitted

a modeling system is provided which is configured to retrieve from the non-volatile memory the 3d virtual model of an object; define a domain of a parametric surface; project feature curves in the 3d virtual model into the domain of the parametric surface to generate a mapping based on the 3d virtual model and including a plurality of parametric curves; divide the plurality of parametric curves into horizontal and vertical feature curves; extend each of the horizontal feature and vertical feature curves; construct a horizontal interpolant connecting the extended horizontal feature curves; construct a vertical interpolant connecting the extended vertical feature curves; fit the horizontal and vertical interpolants as coordinates of a map to a new parametric domain; and compose the inverse of the map to the new parametric domain with the parametric surface to create a new parametric surface containing the feature curves as isoparametric curves.
