An object is composed of a 101 × 101 quadrilateral mesh (i.e., 100 × 100 quadrilaterals). On average, each quadrilateral in the mesh projects to 50 pixels. There are 150 objects in the scene. The graphics monitor has resolution 2560 × 1440. Estimate the number of elementary operations needed by i) Z buffer ii) Ray casting for which the objects are all spheres iii) Ray casting for which the objects are all complex. For this question, assume that it is easy to test whether a pixel ray intersects a triangle

Background and formula: Ellipse has two types of axis - Major Axis and Minor Axis. The longest chord of the ellipse is the major axis. The perpendicular chord to the major axis is the minor axis, which bisects the major axis at the center as shown in Figure 1. Ellipse is different with circle which has only one radius. There is no simple formula to calculate the exact or accurate value of perimeter of an ellipse. Therefore, we use approximation formulas to calculate the approximate value of an ellipse's perimeter. One of the approximation methods is called Ramanujan Formula as follows: p zn[3(a+b) – Г(За + b) (а + зь)| where a is the semi major axis and b is the semi minor axis of the ellipse, respectively, as shown in Figure 1. be major axis Figure 1.

Scaling Transformations: A 2D point can be scaled by multiplication of the coordinate values (x,y) by scaling factors Sx and Sy to produce the transformed coordinates (x,y'). Translation Transformations: A 2D point can be translated by adding the coordinate values (x,y) by Translation distances Tx and Ty to produce the transformed coordinates (x,y'). Rotation Transformations: A 2D point can be rotated by repositioning it along a circular path in the xy plane. We specify the rotation angle and the position of the rotation point about which the object is to be rotated. Multiplication of the coordinate values (x,y) by rotation matrix produce the transformed coordinates (x,y'). Now you have to design a program which will provide you with the option that which type of transformation you want to do. Like the following, Enter your choice: 1. Translation 2. Scaling 3. Rotation 4. Exit After providing the choice you have to enter the number of edges of a polygon and then you have to input the…
