Image Generation

• There is a related but different field of image generation.
• Here you have models of objects and light sources, and want to generate pictures and films.
• When would you do this?
• In video games, you need to develop the pictures in real time so that the objects move well.
• You need to cope with light sources, shading, reflection and occlusions.
• There are lots of techniques to improve these, and games engines use them.
• Movies are a different problem. You want to use cgi effects, but you don't care about real time. You care about end quality.
• Here you can spend longer working with the details.
• You still want to have fast algorihtms, as these can take a lot of computer time.
• Can you see how this is the flip side of the vision problem?
