Try a few Computer Graphics questions

Ray tracing is a computer-graphics technique designed to simulate what?

Answer: The paths of light rays

Bonus fact: It can produce realistic reflections, shadows, refraction, and global lighting effects.

Why has real-time ray tracing historically been computationally expensive?

Answer: It requires tracing many light paths and intersections

Bonus fact: Modern GPUs include specialized hardware to accelerate the geometric calculations ray tracing needs.

What is path tracing?

Answer: A ray-tracing method that estimates global illumination by sampling many light paths

Bonus fact: Path tracing can create highly realistic lighting but often needs many samples to reduce visual noise.

Raster graphics are made up of a grid of what?

Answer: Pixels

Bonus fact: Photographs and most screen images are commonly represented as raster graphics.

What happens when a low-resolution raster image is enlarged too much?

Answer: It becomes visibly pixelated

Bonus fact: Each pixel covers more screen area, so the square structure becomes noticeable.

Which file format is commonly used for lossless raster graphics with transparency?

Answer: PNG

Bonus fact: PNG is well suited to interface graphics, screenshots, and images that need alpha transparency.
