3D graphics are graphics that look more realistic because they are three-dimensional. This means the computer thinks it has a height, a length and a depth, and displays them as we would see them in the real world with our eyes. Among other things they use solid geometry and trigonometry to create correct perspective. Some programs used to make 3D graphics are Bryce, 3D Studio Max, Maya and Blender. 3D graphics are used many times in movies and TV shows and video games.
