A computer model for a hot gas-fluidized bed has been developed. The theoretical description is based on a two-fluid model ( TFM) approach in which both phases are considered to be continuous and fully interpenetrating. Local wall-to-bed heattransfer coefficients have been calculated by the simultaneous solution of the TFM conservation of mass, momentum and(More)
To illustrate the difficulties consider IATM's tragic-comic hero, Scrat: It features over 1.3 million hairs modeled as b-spline curves with 6 control points, where each control point has 3 coordinates, color and opacity values. Adding supporting data for deformation blur, bounding boxes and subdivision of the b-spline into bezier segments, the scrat's fur(More)
Even a casual search turns up many renderers that call themselves "production renderer"---some of them relatively unknown, others known to be of very high standard. In addition to these sources, many of the large studios have their own renderers, investing significantly into the resources required to develop this technology. This panel explores the reasons(More)
