Point Based Rendering

Overview:

Point-based rendering is a new rendering paradigm that uses sample points from surface models as display primitives. In our project, we examine the application of multi-resolution hierarchies of point primitives to render highly complex scenes in output-sensitive time. The usage of multi-resolution point based rendering allows to display of scenes described by several billion primitives at interactive frame rates.

 

Sub-Projects:

The Randomized z-Buffer Algorithm (SIGGRAPH 2001)

In this sub-project, we examine efficient dynamic sampling and image reconstruction strategies for point based rendering of highly complex models.

Multi-Resolution Rendering of Complex Animated Scenes (EUROGRAPHICS 2002)

In this sub-project, we apply point based rendering techniques to render highly complex keyframe animations.

Interactive Rendering of Large Volume Data Sets (VISUALIZATION 2002)

Point Based Rendering is closely related to volume rendering. Indeed, PBR is just volume rendering of sparse volumetric data sets. This sub-project examines efficient rendering of fully volumetric data sets.

multi-resolution raytracing Multi-Resolution Point-Sample Raytracing (GRAPHICS INTERFACE 2003)

In this sub-project, we examine how prefiltered point hierarchies can be used to perform efficient antialiasing in the context of raytracing.

caustics Real-Time Caustics (EUROGRAPHICS 2003)

In this sub-project, we propose an algorithm to render certain caustics effects in real-time using a combination of surface sampling and hardware shading techniques.

sound rendering Multi-Resolution Sound Rendering (SPBG 2004)

The same sampling techniques that allow a rapid visualization of complex scenes can also be used to perform sound rendering in complex sound environments. This sub-project examines this idea more in detail...
