Motivations
- Explore the relation between time and photography.
- Identify the advantages provided by Ray Tracing to simulate motion photography.
- Explore the tools provided by PBRT to construct and render dynamic scenes.
Goal
- Develop a framework to deal with light events (flashes) and changes in light intensity.
- Extend the existing animated transformations to more complex and still realistic movements.
- Compare rendering results for some dynamic light configurations.
- Implement a rendering technique to efficiently generate images with dynamic lights and dynamic objects.
