<para> As CT scanning is a very common medical imaging method, we propose new hardware-based algorithms using GPU (Graphical Processor Unit) programming for rapid visualization. Firstly, 3D volumes are constructed from CT scans. Then volume rendering is used to display anatomical structures via algorithms founded on improved ray casting and 2D textures. Our methods achieve interactive rendering...
In collaborative virtual environment system, to render 3D models on Web based on a unified modeling kernel is a challenging issue. Previous technologies of Web 3D rendering mainly concentrate on the technology of visualization and interaction, and typically Web 3D models are rendered with surface model. In this paper, we develop a novel Web 3D viewer based on STEP/AP203 kernel, and the relation of...
