What are the uses of Bezier Curves and Bezier Surfaces? Explain the Mathematical expression of Bezier Curves. Write the properties of the Bezier curves, prove all properties. Discuss the Parametric Continuities and Geometric Continuities of Bezier Curves, with suitable expressions, equations and examples. Explain the purpose of control points in Bezier, a Cubic Bezier curve has control points P0 (0, 0); P1 (5, 40); P2 (40, 5); P3 (50, 15). Determine 2 more points on the same Bezier curve. Draw a rough sketch of the curve and show coordinates of various points on it?

Simulating Accelerations in Computer Animations

Write and discuss Z-Buffer algorithm with suitable example. What are the maximum number of objects that can be handled by the Z-buffer algorithm? What will happen if Z-buffer algorithm is used and it is found that two polygons have same Z-value?

Differentiate between Euclidean Coordinate System and Homogeneous Coordinate system. Discuss the advantage of Homogeneous Coordinate system over Euclidean Coordinate System. Assume that a polygon ABCDE has the coordinates A(0, 0), B(10,10), C(10,2),D(5,5),E(7,6) is subjected to the clockwise rotation of 45° about an axis passing through the centroid of the polygon, find the final coordinates of the polygon ABCDE. You should represent the transformation using Homogeneous Coordinate System.
