چکیده
In this paper we present an Image-Based Rendering method for post-warping LDI’s in real-time on existing systems. The algorithm performs accurate splatting at low computational costs, reduces memoryaccess bottlenecks, enables us to trade-off the quality for the speed, and is simple to implement.

The 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 کاملA 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 کاملCylindrical Relief Textures Mapping
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 wa...
متن کاملThe EM Algorithm for Layered Dynamic Textures
A layered dynamic texture is an extension of the dynamic texture [1] that can model multiple regions (layers) of different motion. The motion in each layer is abstracted using a time-evolving state process, and each pixel formed from one of the state processes, which is assigned through a layer assignment variable. In Section 2 and Section 3, we derive the EM algorithm for learning the layered ...
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...
