    Sammanfattning : In the real world, the visual perception of an object is completely determined by the object's interactions with light. One large application of computer graphics is to visualize virtual objects and worlds in a fashion that is familiar to humans. Successfully emulating light and its effects on virtual objects therefore plays a central role. LÄS MER

  7. 5. Studies of Edge Diffraction and Scattering: Applications to Room Acoustics and Auralization

    Författare :Rendell Torres; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffraction; virtual environments; scattering; diffusion; architectural acoustics; auralization; virtual reality; room acoustics;

    Sammanfattning : This thesis examines ways of including edge diffraction and surface scattering to improve room acoustics auralization, i.e., the binaural replication of an acoustic environment. The approach combines numerical and psychoacoustical studies to discern what level of computational accuracy is necessary to obtain perceptually adequate replication. LÄS MER
