Rendering - sec 02

What is rendering?

• Converting 3D scene to 2D image.

• Determine the color of the 3D scene.

• Determine how object surface interact with lights.

• Compute the light intensity in the scene.

What is the primary advantage of using ray tracing over rasterization?

• Faster rendering times.

• Enhanced realism in lighting and reflections.

• Reduced computational requirements.

• Simpler algorithmic structure.

When processing each scan line, the scan line algorithm:

• Ignores hidden surfaces.

• Only renders edges of polygons.

• Determines visible surfaces and fills polygons.

• Renders 3D models directly.

Which of the following effects can be realistically simulated using ray tracing?

• Motion blur.

• Simple shading.

• Low-polygon models.

• Reflections and refractions.

Ray tracing can be computationally expensive because it:

• Traces multiple rays for each pixel.

• Uses a large amount of memory.

• Ignores light calculations.

• Requires high-resolution textures.
