Image-Based Rendering using Image-Warping – Motivation and Background

نویسنده

  • Leonard McMillan
چکیده

The field of three-dimensional computer graphics has long focused on the problem of synthesizing images from geometric models. These geometric models, in combination with surface descriptions characterizing the reflective properties of each element, represent the scene that is to be rendered. Computationally, the classical computer-graphics image synthesis process is a simulation problem in which light’s interactions with the supplied scene description are computed.

Image-Based Rendering using Image Warping

In this report, I present a complete image-based rendering system. This includes the derivation of a mapping function from first principles, an algorithm for determining the visibility of these mapped points in the resulting image, and a method for reconstructing a continuous image from these mapped points. I refer to this type of mapping function as image warping, because it processes the elem...

Motion Consistency for Image-Based Rendering

This paper presents an enhancement to current image-based rendering methods. It suggests that motion consistency can be used in a realtime dynamic rendering system to increase computational efficiency up to one order of magnitude. Parameterization of the image warping function with respect to the viewer’s motion can be used to provide an efficient method for extrapolating new viewpoints using a...

Efficient displacement Mapping by Image Warping

Abstract. While displacement maps can provide a rich set of visual detail on otherwise simple surfaces they have always been very expensive to render. Rendering has only been done using ray tracing or by introducing a great number of micro-polygons. We present a new image-based approach by showing that rendering displacement maps is sufficiently similar to image warping and introduce a new warp...

Three-Dimensional Image Warping on Programmable Graphics Hardware

Many image-based rendering systems are based on three-dimensional image warping (3D Warping), which transforms pixels in reference image to destination view. However, the original 3D warping equation, proposed by McMillan and Bishop, is derived under one special coordinate system, making its inability of direct implementation on programmable graphics hardware. In this paper, we revisit the 3D w...
