Question

if you need to model an animation where a characters arm moves but does not change in length or width, which type of transformation would you use?
○ a combination of non - rigid transformations
○ rigid transformation
○ non - rigid transformation
○ a combination of rigid and non - rigid transformations

Explanation:

Rigid transformations preserve shape and size. Since the character's arm moves without changing in length or width, it is a rigid - body motion. Non - rigid transformations change shape or size. A combination of both would involve changes in shape/size along with rigid motion. So, a rigid transformation is appropriate here.

Answer:

rigid transformation
