Perceptually Driven Point Sample Rendering

چکیده
> Motivation = Visible difference between renderings from refined geometry and coarser geometry is not constant over the image plane (see figure below) = The computational effort for refining should be aimed to the features, which cause highest difference > Problem = Evaluation of visible differences is too expensive to be done in realtime > Our strategy = Perceptual analysis is done as a preprocess = Results are stored with the model = During rendering, those data are used to control the refinement 4. Possible Pitfalls of Perception Preprocessing > Visual difference between two levels of detail is dependent on many parameters: = viewing position = viewing distance = adaptation luminance = rendering technique = lighting model = light direction and parameters = ...

A Progressive Rendering Algorithm Using an Adaptive Perceptually Based Image Metric
In this paper, we propose to solve the global illumination problem through a progressive rendering method relying on an adaptive sampling of the image space. The refinement of this sample scheme is driven by an image metric based on a powerful vision model. A Delaunay triangulation of the sampled points is followed by a classification of these triangles into three classes. By interpolating each...
متن کاملPerceptually Driven Interactive Rendering
We present a framework for accelerating interactive rendering, grounded in psychophysical models of visual perception. This framework is applicable to rendering techniques that regulate resolution—and hence rendering load—using a hierarchy of local simplification operations. Our method drives those local operations directly by perceptual metrics: the effect of each simplification on the final i...
متن کاملImage-Driven Procedural Texture Specification
In this paper we describe an approach to the automated specification of procedural textures to be used in rendering, based on representative samples. Procedural textures exhibit many advantages over traditional surface texturing techniques, but unfortunately finding the correct procedural texture and appropriate parameters to create the desired texture can be a daunting task for even the most e...
متن کاملCS 667 Lecture 15 : Perceptually Based Image Synthesis 31 March 2005
The three basic steps involved in generating photo-realistic images are modeling, rendering, and imaging. Modeling can be considered to include building the geometry of the scene being rendered, plus assigning material properties to all the surfaces. Rendering is the process of simulating light transport to determine the luminance values at every point in the scene. The final step, imaging, is ...
متن کاملA Perceptually Driven Investigation of Point-sampled Soft Shadows
Rendering shadows quickly is an active area of computer graphics research. This dissertation improves the practicality of using a small number of point-sampled light sources to approximate soft shadows. Results are presented from two perceptual experiments demonstrating the perceptual efficacy of soft shadows as spatial cues for a specific set of tasks . A third experiment found coarse point-sa...
