Tools: Polygonized Viewer (P-View)
PView was designed to allow the visualization of datasets obtained from Confocal Laser Scanning Microscopy (CLSM). It allows the user to interact with a pre-computed model using a flight simulator type interface. The program makes use of several optimizations to allow visualization of large objects using standard PC workstation hardware. These include Level of Detail and Frustum Culling. Level of Detail (LOD) is a technique used to speed up rendering of objects. It does this by storing models at various resolutions. Since low resolution models render faster due to their lower polygon count, these are used when the object is more distant from the camera. Higher resolution models are used when the object comes close to the camera. Frustum Culling is another speed up technique. The idea here is that a simple test can be used to determine if an object is out of the view before it is sent to the rendering pipeline. This saves time because the test can be performed in a fraction of the time it would take to render the entire object. To take advantage of this technique all objects are stored as a set of sections defined by axis aligned bounding boxes (AABB).
