Crash Course 27

What is the process called where 3D coordinates are transformed onto a 2D plane in graphics algorithms?

• Texture mapping

• Rendering

• Projection

• Shading

What are the shapes called that are better suited for defining more complex 3D graphics than simple shapes like cubes?

Which lighting algorithm is basic and can make polygon boundaries noticeable and the mesh appear unsmooth? (2 words)

What does the term 'texture mapping' refer to in graphics?

• The process of adding detail and color to a surface

• The algorithm for rendering shadows on objects

• The technique for optimizing rendering speed

• The method for generating 3D effects on 2D planes

What type of projection in 3D graphics makes parallel sides in a cube appear as parallel in the projection?

• Perspective Projection

• Orthographic Projection

• Fisheye Projection

• Panoramic Projection

What happens to a pixel that is entirely inside a polygon during the fillrate process?

• It gets a darker shade

• It remains unchanged

• It gets fully colored

• It becomes transparent

Which algorithm sorts polygons from farthest to nearest before rendering?

• Quick Sort

• Painter's Algorithm

• Depth Sorting

• Bubble Sort

What does Z-Buffering help maintain in a 3D scene?

• The lightest distance to a polygon

• The average color intensity

• The closest distance to a polygon for every pixel

• The highest elevation in the scene

What is the purpose of using textures in scanline rendering?

• To increase rendering speed

• To save memory

• To map between the polygon's coordinates and the texture image saved in memory

• To enhance the 3D effect

The rate at which a computer fills in polygons is called the
