Interactive manipulation of multiresolution curves

چکیده
A new method for manipulation of curves in several degrees is presented. When a point of curve is moved, it a ects a relative local segment, which size could depends of the propagation of the point through their lower resolution curves. So, for the same displacement of the point, could be generated relative local segments of di erent sizes, only varying a local parameter such sti ness constant. We direct manipulation to produce local deformation on each resolution curve, so does not necessary to use energy terms for deformation. We have tested our ideas in a prototype system for modelling uniform B-spline curves and the B-spline wavelets. Using this method, the designer can interactively modi es, in a natural manner, the curve by controlling the size of segment a ected.

Reconstruction of Multiresolution Terrain Surfaces
Multiresolution surfaces are especially useful for fast rendering, real-time display and interactive manipulation of large and dense terrain surface models. This paper reviews major multiresolution terrain surface reconstruction techniques and analyses the corresponding data structures. We have proposed and implemented, based on Delaunay retriangulation, a greedy refinement algorithm with a str...

Adding the ability to merge curves using Boolean operations will allow one to merge a circle with the tip of the wing, making it feasible to precisely design the cross-section of the missile. The techniques presented herein with the aid of the NUBS representation can be easily enhanced to support these features. The method pre...
متن کاملMultiresolution control of curves and surfaces with a self-similar model
This paper presents two self-similar models that allow the control of curves and surfaces. The first model is based on IFS (Iterated Function Systems) theory and the second on subdivision curve and surface theory. Both of these methods employ the detail concept as in the wavelet transform and allow the multiresolution control of objects with control points at any resolution level. In the first ...

متن کاملE cient Error Calculation for Multiresolution Texture-based Volume Visualization
Multiresolution texture-based volume visualization is an excellent technique to enable interactive rendering of massive data sets. Interactive manipulation of a transfer function is necessary for proper exploration of a data set. However, multiresolution techniques require assessing the accuracy of the resulting images, and re-computing the error after each change in a transfer function is very...
