Introduction
Estimated Marks : 5
Small theoritical chapter. You will learn terminologies in computer graphics like pixel, aspect ratio etc. Watch in 2x and quickly complete it.

Very important chapter. Sure minimum 10 marks from this chapter. You will learn how to draw line, circle and ellipse in computer using algorithms. This chapter is bit hard (lots of formula to remember). Derivation is not asked in exam, you are asked how you can use X algorithm to draw Y.

2D Transformation
Estimated Marks : 10
Sure 5 marks (maybe 10 also). This chapter requires some mathematics and you must know about Matrix beforehand. Also a tip, transformation matrix might look different for same transformation and that is due to column wise or row wise matrix representation, so that get confused on that.

3D Transformation
Estimated Marks : 10
Likely 5 marks but maybe 10 marks also. A bit hard topics in my opinion. It takes some time to fit into head the 3D view pipeline (as it is more complicated than 2D view pipeline). For exam perspective, properly practice 3D transformation. Perspective topics are bit more tough to get your head around first time. Do check your book for perspective projection numericals, I could not find videos on that.

3D Object Representation
Estimated Marks : 5
A lot of theory and some decently hard numericals. Mainly focus on numerical related to creating Bezier Curve, Hermite Curve, B-Spline Curve equations. 5 marks numerical question is likely to be asked on that. Spline curve (or cubic spline curve ) is for concept, in exam you will likely be asked about Hermite Curve (a variation of cubic spline curve). I have divided the chapter into 2 parts: Theory and Numerical Related to Curve. Quickly skim through theory (maybe a theoritical question is asked in exam) and then cover the curve numericals. Have patience as some numericals might seem hard for the first time.

Sometime 5 marks question is asked from this chapter. But I dont recommend to learn entirely new tech for just 5 marks. I will recommend you to rather focus on other chapters.
