Realistic modeling and animating clouds are ones of the hardest tasks in computer animation. there are different techniques used in computergraphics for representing clouds. Our work is based on volume-rendered implicit function for volumetric cloud modeling. Basically, implicit primitives are controlled by a modified particle system. We propose genetic algorithms for initialization of the particle system. they provide an alternative to traditional optimization techniques and are also useful in the key-frame animation. Additionally, we introduce some new ideas in volumetric clouds animation: advanced techniques for controlling a large collection of individual elements - flocks and autonomous behavior. Some properties of these techniques are also applicable in the cloud animation.

the effects of type and knowledge of objectives of instruction on the learning outcomes are determined. Two experimental variables, in particular type and knowledge of the objectives are combined for treatments in teaching 'Design Process.' Student-subjects are assigned randomly to one of six experimental conditions or a learning control condition. It is found that neither knowledge of the objectives nor the type of objectives have influence performance on a criterion test.
We describe a pure divide-And-conquer parallel algo- rithm for computing 3D convex hulls. We implement that algorithm on GPU hardware, and find a significant speedup over comparable CPU implementations.

the explosive development of Information Technology opens new perspectives in Electronic Packaging education and evaluation, eliminating the routine from teacher's job and helping him to focus on the principles. As a part of continuous activity of improving the education level, our team I had successfully developed, tested and used a flexible software platform for training and evaluation in the field of Electronic Components. the paper focuses on the main capabilities of this software and describes the problems that were met in practice, as well as its future developments.
