Cylindrical Relief Textures Mapping

چکیده
This paper describes a new Image Based Rendering technique aimed at increasing the realism of textured cylindrical surfaces by adding 3D details and enhancing the depth conceived by the viewer. Cylindrical relief texture mapping extends the existing work on planar relief textures by using cylinders as warp surfaces. After mapping the planar relief texture to a reference cylinder, cylindrical warping equations are used to generate an intermediate image for texture mapping the reference cylinder and introducing motion parallax. The strength of the technique is demonstrated by the visual realism provided, with examples showing how the proposed method can be used for generating depth enhanced panoramas and improved endoscopic simulations.

A Parallel Approach for Visualization of Relief Textures
With the continuous increase of processing power, the graphic hardware – also called Graphic Processor Unit (GPU) – is naturally assuming most part of the rendering pipeline, leaving the Central Processor Unit (CPU) with more idle time. In order to take advantage of this when rendering relief textures, the present work proposes two approaches for the mapping of relief textures. Both methods are...
متن کاملRelief Textures
We have developed a new method for transforming images with per-pixel displacements into textures that have correct parallax when texture-mapped, in the usual way, onto polygons. Our new method results from factoring the 3-D image-warping equations of McMillan and Bishop into a prewarp followed by standard texture mapping. The pre-warp handles only the parallax effects resulting from the direct...
متن کاملDesign-driven modeling of surface-textured full-film lubricated sliding: validation and rationale of non-standard thrust observations
Our recent experimental work showed that asymmetry is needed for surface textures to decrease friction in full-film lubricated sliding (e.g. thrust bearings) with Newtonian fluids; textures reduce the shear load and produce a separating normal force [1]. However, standard slider bearing theory cannot explain the sign of the observed normal thrust, and any effort to optimize surface textures wou...
متن کاملThe effect of texture relief on perception of slant from texture.
Texture can be an effective source of information for perception of slant and curvature. A computational assumption required for some texture cues is that texture must be flat along a surface. There are many textures which violate this assumption, and have some sort of texture relief: variations perpendicular to the surface. Some examples include grass, which has vertical elements, or scattered...
متن کاملRefinement of Facade Models Using Image Sequences
Three dimensional building models have become important during the past years for visualization of touristic or historic objects. Detailed facade models are essential for realistic impressions on a terrestial observer. Such models require both a geometric component that describes the shape of the building or parts of it as well as a texture component that provides color information and depicts ...
