Rendering diffuse objects using particle systems inside voxelized surface geometry
نویسندگان
چکیده
This paper presents an unique method for rendering complex shapes as fuzzy or diffuse objects inside virtual environments. It uses surface geometry that is converted into a voxel-like grid to specify the appearance of the shape. A particle system displays the outline of the object at runtime. Particles are allowed to move freely inside the voxel-grid but obtain certain attributes from the voxels they currently reside in. Those attributes assign color, size, textures, transparency to the particles, as well as forces that influence the movement of the particles. Force effects include linear and spiral movements, gravitational points, and helix-shaped motion of particles. Through this, complex movement of the particles inside the voxel-space can be created at interactive rates, while still maintaining the approximate form of the original surface geometry.

Efficient, High-Quality, GPU-Based Visualization of Voxelized Surface Data with Fine and Complicated Structures
This paper proposes a GPU based method that can visualize voxelized surface data with fine and complicated features, has high rendering quality at interactive frame-rates, and provides low memory consumption. The surface data is run-length-encoded (RLE) for each level-of-detail. Then, the loop for the rendering process is performed on the GPU for the position of the viewpoint at each time insta...

We present a non-traditional approach for ight simulationand training, mission planning and rehearsal. It involves photo-realistic volume-based modeling and rendering of real world terrains from a single elevation map and a satellite or aerial photograph of the terrain. This has been achieved using voxelization, 3D texture splatting and ray-casting. We demonstrate the ability of our approach to...

We present a real-time subsurface scattering simulation to perform real-time rendering of translucent particle-based fluids. After particle-based fluid simulation, we immediately build voxelized fluids, called Voronoi fluids, with particle locations and neighbour lists using GPUs. And then, we perform a multiple subsurface scattering simulation over the Voronoi fluids with the diffusion equatio...

In computer graphics (CG), making photorealistic images using a computer is now commonplace. As a result, directors can create convincing, imaginary worlds, and designers can virtually prototype, visualize, and evaluate potential products and spaces. In order to achieve these purposes, rendering methods such as ray tracing and radiosity rendering methods have been developed. However, the render...
