Fast And Accurate 3D Rendering Of Automotive Coatings

The color of automotive coatings varies with illumination and detection angles. For 3D rendering of these coatings currently two categories of methods exist, aiming at either color accuracy or at computational speed. Current methods that aim for color accuracy are based on measurement data from BRDF instruments. Since many hundreds of measurement geometries are needed to capture the color varia...

A Flexible and Scalable Rendering Engine for Interactive 3D Graphics

Ray-tracing is well-known as a general and flexible rendering algorithm that generates high-quality images. But in the past, raytracing implementations were too slow to be used in an interactive context. Recently, the performance of ray-tracing has been increased by over an order of magnitude, making it interesting as an alternative to rasterization-based rendering. We present a new rendering e...

A 3d Real Time Rendering Engine for Binaural Sound Reproduction

A method of computationally efficient 3D sound reproduction via headphones is presented using a virtual Ambisonic approach. Previous studies have shown that incorporating head tracking as well as room simulation is important to improve sound source localization capabilities. The simulation of virtual acoustic space requires to filter the stimuli with head related transfer functions (HRTFs). In ...

Resonant-Based Identification of the Elastic Properties of Ceramic Coatings

The elastic properties of the individual layers of layered materials can be derived from the resonant frequencies of a set of test specimens comprising samples with different layer configurations [1]. Based on this, a mixed numerical-experimental framework for the identification of the elastic properties of layered materials has been formulated and a number of different identification routines ...
