Approximation of variable-radius offset curves and its application to Bézier brush-stroke design
We present an algorithm to approximate the variable radius ooset curves by cubic B ezier curves. The ooset curve is approximated by a cubic B ezier curve which interpolates the positions and derivatives of the exact ooset curve at both end points. Thus, it approximates the exact ooset curve very closely near the curve end points, but not necessarily in the middle of the curve. Given a xed base ...
متن کاملError bounded variable distance offset operator for free form curves and surfaces
Most o set approximation algorithms for freeform curves and surfaces may be classi ed into two main groups The rst approximates the curve using simple primitives such as piecewise arcs and lines and then calculates the exact o set operator to this approximation The second o sets the control polygon mesh and then attempts to estimate the error of the approximated o set over a region Most of the ...
متن کاملRandom Offset Curves and Surfaces with Controllable Noise
We introduce a novel parametric representation called ROPN (Random Offset Parametric representation with Noise), which is useful to represent a family of shapes sharing similar complex patterns often being able to be defined with the gradient noise functions. PORN is defined by replacing a static offset distance in a general offset with a gradient noise function. For example, PORN curve Cn(t) i...
متن کاملReal-Time Offset Surfaces Real-Time Offset Surfaces
We present a novel technique for the direct rendering of offset surfaces for polygonal meshes. The visible part of the offset surface of each triangle, defined as the union of three spheres, three cylinders and a prism, is constructed in a shader program utilizing the geometry shader. Our method creates exact offset surfaces, up to pixel resolution. Possible applications are real-time visualiza...
متن کاملTrimming local and global self-intersections in offset curves/surfaces using distance maps
A robust and efficient algorithm for trimming both local and global self-intersections in offset curves and surfaces is presented. Our scheme is based on the derivation of a rational distance map between the original curve or surface and its offset. By solving a bivariate polynomial equation for an offset curve or a system of three polynomial equations for an offset surface, all local and globa...
