Unformatted text preview: impossible to write a robust IK solver and as a result people typically use motion capture algorithms.
______ Standard kinematic algorithms assume that articulated structures will have a ring topology.
______ In 2D all IK problems have simple closedform solutions.
______ In 3D all IK problems have simple closedform solutions.
______ The Jacobian of a valid kinematic system will never be invertible.
______ When representing directions in 3D using homogenized coordinates, the fourth coordinate
(i.e. “w”) will be zero.
______ Overly large timesteps can cause a spring and mass simulation to go unstable.
______ Motion capture data is often used in video games.
______ Animations lacking motion blur may suffer from unnatural looking artifacts.
______ The rendering equation discussed in class does not account for atmospheric scattering. Final Exam CS 184: Foundations of Computer Graphics
Spring 2008
Prof. James O’Brien page 3 of 12 ______ The radiosity method operates from the assumption that all surfaces act like diffuse reflectors.
______ Polished plastic surfaces typically have bright white specularities.
______ Although photon mapping is an effective rendering technique, it is seldom used in practice
because of its inability to model area lights.
______ Ambient occlusion approximates global illumination by making diffuse shading proportional to the unoccluded area over a surface.
