Real-time BCC Volume Isosurface Ray Casting on the GPU

چکیده
This paper presents a real-time GPU (graphics processing unit) ray casting scheme for rendering isosurfaces of BCC (bodycentered cubic) volume datasets. A quartic spline field is built using the 7-direction box-spline filter accompanied with a quasiinterpolation prefilter. To obtain an interactive rendering speed on the graphics hardware, the shader code was optimized to avoid lookup table and conditional branches and to minimize data fetch overhead. Compared to previous implementations, our work outperforms the comparable one by more than 20% and the rendering quality is superior than others.

Multi-View Isosurface Ray-casting
In this paper the GPU implementation of a real-time isosurface volume-rendering system is described in detail, which aims at autostereoscopic displays. Since autostereoscopic displays provide images for many views, and thus require different camera settings in each pixel, and even in the three color channels of a pixel, naive rendering approaches would slow down the rendering process by a facto...

متن کاملVolume and Isosurface Rendering with GPU-Accelerated Cell Projection*
We present an efficient GPU-based implementation of the Projected Tetrahedra (PT) algorithm. By reducing most of the CPU–GPU data transfer, the algorithm achieves interactive frame rates (up to 2.0 M Tets/s) on current graphics hardware. Since no topology information is stored, it requires substantially less memory than recent interactive ray casting approaches. The method uses a two-pass gpu a...
متن کاملGPU Accelerated Voxel Traversal using the Prediction Buffer
The ever increasing size of data sets for scientific and medical visualization demands new isosurface volume rendering techniques to provide interactivity for the large datasets. The main obstacle to achieving interactivity is the computational bottleneck due to the dataset traversal and the corresponding amount of data transfer. We propose a novel GPU based dataset traversal technique that use...
متن کاملReal-time ray casting of algebraic B-spline surfaces
Piecewise algebraic B-spline surfaces (ABS surfaces) are capable of modeling globally smooth shapes of arbitrary topology. These can be potentially applied in geometric modeling, scientific visualization, computer animation and mathematical illustration. However, real-time ray casting the surface is still an obstacle for interactive applications, due to the large amount of numerical root findin...
