Guaranteed Marks Plan

How to approach each part of the Computer Graphics exam for maximum marks.

Part A

25 MCQs × 1 = 25 marks

Target: 20–23 / 25

DDA vs Bresenham's Line Algorithm — properties & differences 6/6
2D Transformation matrices — Translation, Rotation, Scaling 6/6
Homogeneous coordinates concept 5/6
Cohen-Sutherland — region codes & outcodes 6/6
Midpoint Circle Algorithm steps 5/6
Z-Buffer algorithm working principle 5/6
RGB vs CMY vs HSV colour models 5/6
Phong vs Gouraud shading differences 4/6
Types of projection — Parallel vs Perspective 4/6
Bezier curve properties and degree 4/6

Part B

5 Questions × 8 = 40 marks

Target: 32–40 / 40

21U1Bresenham's Line / Circle derivation with worked example

22U22D or 3D Transformation — full matrix derivation & numerical 🔥

23U3Cohen-Sutherland Clipping — numerical example with region codes 🔥

24U3/U4Z-Buffer / Scan-line algorithm OR Phong Illumination Model

25U4/U5Colour Models OR Bezier/B-Spline Curve properties

Part C

1 Question × 10 = 10 marks

Target: 8–10 / 10

Choose 1 of 2 questions. Typical options:

Q.26

3D Composite Transformations — multi-step matrix multiplication 🔥 OR Sutherland-Hodgman Polygon Clipping — full step-by-step

Q.27

Visible Surface Detection — BSP Tree or Z-Buffer with diagram OR Ray Tracing / Illumination Model derivation

💡 CGA Exam Secret: Always show the intermediate matrix steps and the final transformed coordinates. Even if the final answer is wrong, well-shown matrix setup earns 6–7 out of 10 marks. Draw a diagram wherever possible!
