Computer Science Technical Report Fast Generation of NURBS Surfaces from Polygonal Mesh Models of Human Anatomy

چکیده
Visible Productions, Inc., of Fort Collins, CO, produces 3-D human models that are recognized as some of the most accurate models in the world. Their models currently are based on meshes of 3-D triangles. Such meshes can be rendered as smooth surfaces by interpolating color values across a triangular mesh, but for a number of applications the smooth surface must be explicitly represented. Clients for Visible Productions' models have asked for surfaces de ned by NURBS (Non-Uniform Rational B-Splines). This project developed and implemented algorithms for transforming polygonal meshes into NURBS. This requires a time-intensive, iterative optimization process. We investigated the use of neural networks to by-pass a large part of the optimization process.

Direct boolean intersection between acquired and designed geometry
In this paper, a new shape modeling approach that can enable direct Boolean intersection between acquired and designed geometry without model conversion is presented. At its core is a new method that enables direct intersection and Boolean operations between designed geometry (objects bounded by NURBS and polygonal surfaces) and scanned geometry (objects represented by point cloud data). We use...
متن کاملFast Generation of NURBS Surfaces from Polygonal Mesh Models of Human Anatomy
Visible Productions, Ltd., of Fort Collins, CO, and other companies produce polygon-based, 3-D models of organic structures in humans and animals. There is already a large database of excellent 3-D anatomical models existing that was created at high expense. Figure 1 shows several of the many polygon-based models created by Visible Productions. These models are used primarily for educational us...
متن کاملAutomatic Texture Atlas Generation from Trimmed NURBS Models
A Texture Atlas is a two dimensional representation of a 3D model usable for paint systems or as a sewing pattern. The field of texture atlas generation from polygonal models has been well exploited in the recent years. The developed algorithms work on piecewise linear surface representations, but not on parametric surfaces like NURBS, that are still the main surface representation in CAD syste...
متن کاملA Uni ed Approach for Hierarchical Adaptive Tesselation of Surfaces
The polygonization, or tesselation, of surfaces is a classical problem that has many practical applications in computer graphics and geometric modeling. The problem consists in computing a piecewise linear approximation for a smooth surface described either by parametric or implicit functions. A polygonal mesh is the one of the simplest forms of surface description and therefore is the represen...
متن کاملRay Tracing Non-Polygonal Objects: Implementation and Performance Analysis using Embree
Free-form surfaces and implicit surfaces must be tessellated before being rendered with rasterization techniques. However ray tracing provides the means to directly render such objects without the need to first convert into polygonal meshes. Since ray tracing can handle triangle meshes as well, the question of which method is most suitable in terms of performance, quality and memory usage is ad...
