A Generalization Approach for 3D Viewing Deformations of Single-Center Projections

Trapp, Matthias; Döllner, Jürgen in International Conference on Computer Graphics Theory and Applications (GRAPP) Braz, José; Nunes, Nuno Jardim; Pereira, Joao Madeiras ( Hrsg. ),   3 , Seite 162--170 . INSTICC Press , 2008 .

This paper presents a novel image-based approach to efficiently generate real-time non-planar projections of arbitrary 3D scenes such as panorama and fish-eye views. The real-time creation of such projections has a multitude of applications, e.g., in geovirtual environments and in augmented reality. Our rendering technique is based on dynamically created cube map textures in combination with shader programs that calculate the specific projections. We discuss two different approaches to create such cubemaps and introduce possible optimizations. Our technique can be applied within a single rendering pass, is easy to implement, and exploits the capability of modern programmable graphics hardware completely. Further, we present an approach to customize and combine different planar as well as non-planar projections. We have integrated our technique into an existing real-time rendering framework and demonstrate its performance on large scale datasets such as virtual 3D city and terrain models.
