These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

1. 1 Easy

   What technique smooths jagged edges?

   Answer: Anti-aliasing

   Why: Anti-aliasing blends edge pixels with background colors to fool the eye into seeing smooth curves.

2. 2 Medium

   What household item became a famous test model in 3D graphics?

   Answer: Utah teapot

   Why: The Utah teapot became ubiquitous because its complex curved surfaces and self-shadowing made it ideal for testing renderers.

3. 3 Hard

   Which 4D numbers prevent gimbal lock in 3D graphics rotations?

   Answer: Quaternions

   Why: Quaternions avoid gimbal lock by encoding rotations as a single continuous 4D calculation rather than three separate sequential axis turns.

4. 4 Easy

   What shape builds most 3D graphics models?

   Answer: Triangle

   Why: Triangles are the base polygon because three points are always guaranteed to lie on a single flat plane.

5. 5 Medium

   What GPU program calculates lighting and color in graphics?

   Answer: Shader

   Why: Shaders run thousands of tiny calculations in parallel across GPU cores to shade millions of pixels simultaneously.

6. 6 Easy

   What graphics method tracks light rays to make realistic shadows?

   Answer: Ray tracing

   Why: Ray tracing actually tracks light backward from the camera into the scene to avoid calculating rays the viewer never sees.
