Volume Sculpting and Keyframe Animation System
In traditional animation, keyframes are modeled and standard graphics pipeline is used to animate the scene. In this paper we consider volume animation where the 30 world and its components are represented as a voxel model. The voxel model is annotated with hierarchical feature information and thus facilitates easy volume editing. These annotations are based on regularised Minkowski operators u...
متن کاملParallel interactive virtual machining on shared memory multiprocessors
Interactive sculpting is the process by which a designer can impose free-form shape changes on the object being designed. It has potential applications in the fields like computer aided geometric design arid rapid prototyping. Our approach to interactive sculpting is through the intermediate step of interactive virtual nlachining (IVM). IVM is a subset of interactive sculpting in that the degre...
متن کاملInteractive Modeling of Support-free Shapes for Fabrication
We introduce an interactive sculpting approach that enables modeling of support-free objects: objects which do not require any support structures during 3D printing. We propose three operators – trim, preserve, grow – to maintain the support-free property during interactive modeling. These operators let us define brushes that perform either in an unconstrained manner (adapting the shape to the ...
متن کاملOctree–based Volume Sculpting
A volume sculpting system is presented. The system provides tools for interactive editing of a voxel raster that is stored in an octree data structure. Two different modes of sculpting are supported: Sculpting by adding and subtracting solids, and sculpting with tools that are based on a spray can metaphor. The possibility of extending the method to support multiresolution sculpting is discusse...
متن کاملManipulation of Volumetric Solids with Applications to Sculpting
The topic of this thesis is volume graphics, and in particular techniques which are applicable to volume sculpting. A volume sculpting system is an interactive computer program for shape modelling where the shape is represented volumetrically in a 3D lattice of so–called voxels. It is argued that it is reasonable to classify the tools in a sculpting system according to whether the tools tend to...
