Ray methods in architectural acoustic design

Abstract

Raytracing is a simple but powerful tool in acoustics consulting because of its ability to geometrically approximate wave behavior across a large portion of the audible spectrum. The use of this method requires an understanding of the frequency-dependent interaction between sound waves and geometry, which is a wave-specific behavior that any use of ray-based approximations must consider. The limitations of these approximations may necessitate geometric modifications in a model to render credible results, or may even dictate raytracing is inappropriate for a given application. Ray-based analysis can be used for applications with a wide range of complexity, from hand-traced sketches to computational simulation for full-scale rooms. Common applications include analysis of reflector coverage, design of room shape and major room components, and impulse response simulation for analysis and auralization. Due to their efficiency and simplicity, ray methods remain indispensable in architectural acoustic analysis.

3D Reconstruction and Rendering Models in Urban Architectural Design Using Kalman Filter Correction Algorithm

“…Virtual communities, virtual businesses, online virtual schools, virtual banks, and so on have emerged one after another [5]. Traditional urban planning is mainly represented by handdrawing, architectural miniature model, architectural renderings, and 3D animation [6]. With the rapid development of digital city and the continuous expansion of the application field of urban 3D spatial model, the demand for 3D model of urban buildings is growing.…”
