Terrain Rendering Using Geometry Clipmaps
A primary difficulty in terrain rendering is displaying realistic terrains to the user at real-time frame rates. The brute force approach is usually too complex for real-time frame rates to be achieved. Several terrain-rendering techniques have been proposed that use Level of Detail (LOD) to generate a simplified representation of a terrain. The geometry clipmap is a recently proposed approach ...
متن کاملTerrain Rendering using Geometry Clipmaps
Geometry clipmaps present a quick, intuitive, and high performance solution to the problem of rendering terrain at varying levels of detail (LOD). Recent advances in graphics hardware allow a significant portion of geometry clipmap processing to be done on the GPU, making the performance even better. This paper explores implementing geometry clipmaps on the GPU and discusses the optimizations a...
متن کاملTerrain Rendering Using GPU-Based Geometry Clipmaps
The geometry clipmap introduced in Losasso and Hoppe 2004 is a new level-of-detail structure for rendering terrains. It caches terrain geometry in a set of nested regular grids, which are incrementally shifted as the viewer moves. The grid structure provides a number of benefits over previous irregular-mesh techniques: simplicity of data structures, smooth visual transitions, steady rendering r...
متن کاملHigh-Performance Terrain Rendering Using Hardware Tessellation
In this paper, we present a new terrain rendering approach, with adaptive triangulation performed entirely on the GPU via tessellation unit available on the DX11-class graphics hardware. The proposed approach avoids encoding of the triangulation topology thus reducing the CPU burden significantly. It also minimizes the data transfer overhead between host and GPU memory, which also improves rend...
متن کاملHexagonal Geometry Clipmaps for Spherical Terrain Rendering
Terrains can be rendered efficiently with rectangular 2D grid of heights. Terrain on spheres, on the other hand, can be rendered using Hierarchical Triangular Mesh (HTM) but the representation does not fit directly with 2D grid of heights. We present a unified representation of HTM and clipmapping using Hexagonal Geometry Clipmaps. This provides one to one correspondence of vertices and heights...
