What are the basic rendering techniques?

Basic rendering techniques include rasterization, ray tracing, and scanline rendering. Rasterization converts vector graphics into pixel-based images, making it efficient for real-time applications like Video Games. Ray tracing simulates the way light interacts with objects to produce highly realistic images, though it is computationally intensive. Scanline rendering processes image rows one at a time, making it suitable for certain types of scenes, particularly in older graphics systems.
