We present a novel algorithm for generating a planar parameterization of the region surrounding a curve embedded in a 3D surface, which we call a stroke parameterization. The technique, which extends the well-known Discrete Exponential Map [SGW06], uses the same basic geometric transformations and hence is both efficient and easy-to-implement. We also handle self-intersecting curves, for which ...

We present a botanical simulation of secondary (cambial) tree growth coupled to a physical cracking simulation of its bark. Whereas level set growth would use a fixed resolution voxel grid, our system extends the deformable simplicial complex (DSC), supporting new biological growth functions robustly on any surface polygonal mesh with adaptive subdivision, collision detection and topological co...

The current implementation of OpenGL only supports standard 1-D and 2-D texture mapping. An interface is proposed to extend the OpenGL library, to support a simpli ed model of antialiased procedural solid texturing in OpenGL version 1.1. This extension to the OpenGL language does not modify the existing OpenGL standard. It is designed as a supplemental library that works with existing implement...

To improve the biocompatibility of implants, surface medication is a common practice. Depending on the surface medication process, the physical and/or chemical properties of the surface are altered, keeping the bulk properties same. The flexibility and wide application potential of laser as a surface modification tool gives it certain advantages over the traditional physical and chemical proces...

A hybrid approach based on laser texturing and surface coating for the combined modification of topography chemistry has been proposed to provide a versatile development functional surfaces. The experimental procedure comprised nanosecond pulsed AISI 304 stainless steel substrates followed by deposition thin (<1 µm) coatings with two different technologies, sol–gel PE-CVD, aim independently ...
