Question 27

specify the viewing volume in an ______ by specifying the far, near, left, right, top, and bottom clipping planes

Answer 27

Orthographic/Parallel Projections

Question 28

Objects and figures are then projected to a 2d image that appears on your screen

Answer 28

Orthographic/Parallel Projections

Question 29

Adds the effect that distant objects appear smaller than nearby objects. This type of projection gives the most realism for simulation and 3d animation

Answer 29

Perspective Projections
