Motion Graphics 3D Animation and Motion 1

Question 1

What is a 'camera' object used for in 3D motion graphics software?

Accepted Answer

Defining the viewpoint and perspective through which the 3D scene is viewed and rendered

Answer

A camera in 3D software defines the viewing angle, focal length, and perspective projection through which the scene is rendered to a 2D image.

Question 2

What does 'keyframe interpolation' mean in 3D animation?

Accepted Answer

The method by which values are calculated between two keyframe positions

Answer

Keyframe interpolation is the mathematical method — linear, bezier, step, etc. — used to calculate in-between values between two keyframes.

Question 3

What is a 'polygon mesh' in 3D graphics?

Accepted Answer

A 3D object made of connected vertices, edges, and faces (polygons)

Answer

A polygon mesh is a 3D model composed of vertices, edges, and polygonal faces that define the surface geometry of an object.

Question 4

What does 'rigging' refer to in 3D character animation?

Accepted Answer

Creating a system of bones and controls that allow a character to be posed and animated

Answer

Rigging creates a skeletal system of bones and control handles that animators use to pose and animate a 3D character intuitively.

Question 5

What is 'ambient occlusion' in 3D rendering?

Accepted Answer

A shading technique that calculates how exposed each surface point is to ambient light, darkening corners and crevices

Answer

Ambient Occlusion (AO) simulates the soft shadowing that occurs in corners, creases, and areas where surfaces are close together, adding depth and realism.
