Iterative Parallax Mapping with Slope Information
نویسنده
چکیده
This paper improves per-pixel displacement mapping algorithms. First we review the previous work including bump, parallax, and relief mapping, and also sphere tracing. Then we propose a new iterative algorithm based on parallax mapping, which takes into account the surface slope represented by the stored normal vector. We show that the new method is much better than parallax mapping, however a little poorer than relief mapping, in terms of image quality. However, it is much faster than relief mapping, and is thus a good candidate for implementation in games.

Convergence theorems of multi-step iterative algorithm with errors for generalized asymptotically quasi-nonexpansive mappings in Banach spaces
The purpose of this paper is to study and give the necessary andsufficient condition of strong convergence of the multi-step iterative algorithmwith errors for a finite family of generalized asymptotically quasi-nonexpansivemappings to converge to common fixed points in Banach spaces. Our resultsextend and improve some recent results in the literature (see, e.g. [2, 3, 5, 6, 7, 8,11, 14, 19]).
متن کاملIterative Process for an α- Nonexpansive Mapping and a Mapping Satisfying Condition(C) in a Convex Metric Space
We construct one-step iterative process for an α- nonexpansive mapping and a mapping satisfying condition (C) in the framework of a convex metric space. We study △-convergence and strong convergence of the iterative process to the common fixed point of the mappings. Our results are new and are valid in hyperbolic spaces, CAT(0) spaces, Banach spaces and Hilbert spaces, simultaneously.
متن کاملA modified Mann iterative scheme for a sequence of nonexpansive mappings and a monotone mapping with applications
In a real Hilbert space, an iterative scheme is considered to obtain strong convergence which is an essential tool to find a common fixed point for a countable family of nonexpansive mappings and the solution of a variational inequality problem governed by a monotone mapping. In this paper, we give a procedure which results in developing Shehu's result to solve equilibrium prob...
متن کاملA Hybrid GPU Technique for Real-Time Terrain Visualization
Real-Time terrain visualization plays an important rule in multiple popular applications like geographical information systems, computer games, or civil or militar simulators, where hardware tessellation has become a de-facto standard nowadays in the graphic pipeline. Also, post-processing techniques enhance the appearance of the rendered image by applying changes at the pixel level using the f...
متن کاملUndelayed landmarks initialization for monocular SLAM
We address the problem of landmark initialization in monocular simultaneous localization and mapping (SLAM). The depth dimension is not observable from one monocular measurement, and several observations are required from different vantage points exhibiting sufficient parallax. This makes initialization difficult. Early solutions to the problem performed a parallel task to determine this depth ...
