Volumetric-csg | a Model-based Volume Visualization Approach
نویسندگان
چکیده
This paper presents a Volumetric-CSG (VCSG) method for the representation of volumetric objects and their operation, such as transformations, cutting and Boolean operations. A new volume rendering algorithm is developed for visualizing the VCSG models. The algorithm rst generates optimal target blocks for eecient model operations by adaptive subdivision of the target volume, and then volume renders the target blocks using a template-based octree projection process. Both the raycasting block projection and hardware assisted 3D texture mapping rendering methods are implemented.

New Algorithm for Converting a CSG Representation Into a B-Rep Representation
The purpose of this work is to define a new algorithm for converting a CSG representation into a B-Rep representation. Usually this conversion is done determining the union, intersection or difference from two B-Rep represented solids. We will define another approach where the space used by the solids is determined as a volumetric representation. Then, using the volumetric representation a B-Re...
متن کاملHardware accelerated voxelization
This paper presents a hardware accelerated approach to the voxelization of a wide range of 3D objects, including curves/surfaces, solids, and geometric and volumetric CSG models. The algorithms generate slices of the object models using a surface graphics processor to form the nal volume representations. Boolean operations in a volumetric CSG model are carried out using frame bu er blending fun...
متن کاملConverting CSG models into Meshed B-Rep Models Using Euler Operators and Propagation Based Marching Cubes
The purpose of this work is to define a new algorithm for converting a CSG representation into a B-Rep representation. Usually this conversion is done determining the union, intersection or difference from two B-Rep represented solids. Due to the lack of explicit representation of surface boundaries, CSG models must be converted into B-Rep solid models when a description based on polygonal mesh...
متن کاملFeature-based Volume Rendering of Simulation Data
In this paper we present a framework for interactive volume rendering of high-dimensional flow simulation data. Our approach combines information visualization, flow visualization, as well as volume visualization techniques for volumetric flow visualization. Interactive feature specification by use of multiple linked views and composite non-binary brushes enables selection and multiple definiti...
