New techniques for fast and realistic cumulus cloud rendering are described. Two of the techniques utilize a variation on the Perlin Noise to create suitable cloud-like texture. The other technique is based on a direct volume rendering mechanism. A fractal-based scheme to enable reasonable shape is incorporated into two of the techniques. Sample renderings and performance are also presented.

Barcode detection is required in a wide range of real-life applications. imaging conditions and techniques vary considerably and each application has its own requirements for detection speed and accuracy. In our earlier works we used uniform partitioning with several approaches for detection of various types of ID and 2D barcodes and showed their behaviour on a set of test images. In this work, we extend the partitioning idea and replace scan-line based methods with distance transformation to improve accuracy.

In order to avoid load imbalances on the GPU during direct volume rendering, a common scheme was to move the generation of proxy geometry, that quite often consists of polygons retrieved through box-plane intersections, from the CPU to the vertex stage of the GPU. Nowadays, with the unified shader architectures implemented by modern graphics hardware, usually non of the programmable stages will starve anymore. Nevertheless, redistributing calculations for proxy geometry generation from the vertex stage to the newly introduced geometry stage of the graphics hardware results in some serial computations that can be performed more finely grained, thus hinting the graphics driver to schedule more tasks in parallel. We propose different implementations of box-plane intersection algorithms on the GPU that use the vertex - as well as the geometry stage and compare their performance on modern graphics hardware.
