6. Explain how to render the shadow of the polygonal model on the image plane. Name all element that need for this scene and describe the workflow in details. 7. Realistic simulation of real world objects affected by natural forces may be very time consuming if this is done using key frame animation. Maya integrates several dynamic simulation systems that are optimised for modelling of certain types of interactions. Explain how the nDynamics simulation system can help to create complex animations. 9. Skins of 3D meshes can bulge or indent when the skeleton joints are moved or rotated during animation. What techniques can be used to reduce excessive skin deformations? 10. Explain in detail how Motion Capture works. The explanation should include the technique that determines the position of the marker on the actor from two cameras, the marker-less technology and Inertial Motion Capture technology. What are advantages and limitations of these technologies
