Personal Role:

In phase 1 developing the real-time GPU based rendering pipeline. In phase 2, designing and implementing new LOD paradigms as well as improving the rendering engine performance.

Details

In this project we are developing a novel point-based rendering approach based on object-space point interpolation of densely sampled surfaces. We introduce the concept of a transformation-invariant covariance matrix of a set of points which can efficiently be used to determine splat sizes in a multiresolution point hierarchy.

We also analyze continuous point interpolation in object-space, and we define a new class of parametrized blending kernels as well as a normalization procedure to achieve smooth blending.

Furthermore, we propose a GPU accelerated rendering algorithm based on texture mapping and blending as well as programmable vertex- and pixel-shaders. Experimental results show the high quality and rendering efficiency that is achieved by our approach.
