G3: Rendering Flashcards
What is rendering in the context of graphics?
A subfield in graphics that is concerned with algorithms that generate images from 3D models.
What is the primary goal of rendering?
To approximate how things look in real life.
What does a light source emit in the rendering process?
Photons.
What role does surface geometry play in rendering?
It reflects photons.
What does the camera sensor do in the context of rendering?
It receives photons.
What is the simplification used in rendering?
Ray optics (geometrical optics).
How are lights represented in computer graphics?
Mostly as rays.
What are the two families of rendering algorithms?
Rasterization and Ray Tracing.
What is the focus of the rasterization algorithm?
Determining which pixels are covered by each triangle in a scene.
What does the ray tracing algorithm focus on?
Determining which triangle is visible from each pixel.
In ray tracing, what is the order of computation?
We iterate over pixels first, rather than objects in the scene.
