Shape optimization of curved slots on 3-D surface

In the aeronautic and aerospace thin-walled structures, hole shape designs are very popular to achieve the weight reduction, structural reparation, cooling and other purposes and have important influences on the structural weight, performances and f…

New way to make realistic shadows in computer images

Scientists and computer gamers alike could benefit from a new method for creating soft, realistic shadows in computer-generated images. Engineers at Ohio State University have created computer algorithms that model how light passes through translucent three-dimensional objects or fluids such as water, clouds, fire, and smoke. The result: shadows that begin to approach the realism of Hollywood animation, but don’t require as much computer memory to create.
