Voxel-Based Terrain Generation Using Scalar Perturbation Functions
نویسنده
چکیده
The problem of real-time photorealistic imaging of digital terrain is discussed. New technique for specifying digital terrain by scalar perturbation functions without its approximation by polygons is considered. A recursive algorithm for object space subdivision with masking of invisible surfaces and an effective technique of projective transformation for perspective imaging are proposed. The possibility to visualize photo-realistic terrain is shown. Examples of images obtained by modeling the work of the algorithm with elevation map of defining the digital terrain are presented.

Dynamic Voxel Based Terrain Generation
This project is an implementation of an editable terrain system. By maintaining an octree of volumetric data and performing the mesh creation on the GPU, the program can allow for free editing of the surroundings which is then reflected in real time. This allows for real time applications to have terrain that can change depending on how the user interacts with it.
متن کاملReal-Time Terrain Storage Generation from Multiple Sensors towards Mobile Robot Operation Interface
A mobile robot mounted with multiple sensors is used to rapidly collect 3D point clouds and video images so as to allow accurate terrain modeling. In this study, we develop a real-time terrain storage generation and representation system including a nonground point database (PDB), ground mesh database (MDB), and texture database (TDB). A voxel-based flag map is proposed for incrementally regist...
متن کاملVoxel Column Culling: Occlusion Culling for Large Terrain Models
We present Voxel Column Culling, an occlusion culling algorithm for real−time rendering of large terrain models. This technique can greatly reduce the number of polygons that must be rendered every frame, allowing a larger piece of terrain to be rendered at an interactive frame−rate. This is accomplished by using a form of 3D cell−based occlusion culling. A visibility table for the terrain mode...
متن کاملVirtual Flythrough over a Voxel-Based Terrain
A voxel-based terrain visualization system is presented with real-time performance on general-purpose graphics multiprocessor workstations. Ray casting of antialiased 3D volume terrain and subvoxel sampling in true 3D space produce high quality images. Based on this rendering algorithm, an interactive flythrough system for mission planning and flight simulation has been developed on an SGI Powe...
متن کاملDesign of Multi-dimensional Transfer Functions Using Dimensional Reduction
Direct volume rendering techniques allow visualization of volume data without extracting intermediate geometry. The mapping from voxel attributes to optical properties is performed by transfer functions which, consequently, play a crucial role in building informative images from the data. One-dimensional transfer functions, which are based only on a scalar value per voxel, often do not provide ...
