19. 19

    Anti-Aliasing: A technique used to smooth out jagged edges in images. It makes graphics look cleaner and more realistic.

20. 20

    Texture Mapping: Applies images to 3D models to give them color and detail. It's essential for creating realistic environments.

Challenges in Rendering

Rendering is not without its challenges. Various factors can complicate the process.

21. 21

    Computing Power: High-quality rendering requires significant computing resources. This can be a limitation for smaller studios.
