Assignment No. 02
Semester: Fall 2018

CS602: Computer Graphics


Total Marks: 30


Due Date:31/1/2019


Please read the following instructions carefully before submitting assignment:

It should be clear that your assignment will not get any credit if:

§  The assignment is submitted after due date.

§  The submitted assignment does not open or file is corrupt.

§  Solution is copied from any other source.


The objective of this assignment is to;

§  Learn and practice basic concepts of Refraction Of Light

§  Learn the concept of Normal to the plane

§  Learn the concept of light saturation



Q No. 1

Incident Light ray is passing through glass, with refractive index of 1.1, on an interface separating glass and water with refractive index 1.25. What is the angle of refraction if the angle of incidence of the ray in glass is 35°?


Q NO. 2

Given are the points that lie on a plane P,                       




You are required to find the equation of a normal to the plane P.

Q No. 3

In rgb model we are required to simulate the entire visible spectrum by three colors with a limited range. Suppose a light is coming from a particular source and is represented by following intensity.

Light color id = [0.43314, 0.32632, 0.62343]

Surface color is represented with the following rgb values.

Surface color Cs = [0.23435, 0.62527, 0.32333]

You are required to calculate the color combination of this surface from a given light by using piecewise multiplication of the color values. 

id Cs =?

Submission:You are required to submit your solution through LMS in MS Word format.

Q3 solution idea


you can make it perfect by yourself

but Ans share zror kr dijye ga :) let's see k ks ks ka kia ata hai.? by this will be able to correct errors 

Best of luck.

Q1 mai values wrong hain. 1.1 and 1.25 hai not 1.62 and 1.22

Question 2 ki calculation kis method se ki hai? 

and Question 3 mai multiply theek ni kia hua values ko. 

Javed bhai, srf q1 m nai q2,q3 m b values wrong hai,,it's just idea.!!

q2 ka method bta rha tha,sae sy awaz nai a rhi thi smj m.?

q3 m kia ap bta skty hain kasy multiply krna hai.? plz

m ny first du kr liye hain,,but ap clear kr dain k kasy q 3 ki mulitplication krni hy.?

complete karny k bad kindly share kar dena file.

Shabir kia ap bta skty k Q.1 main n1 main glass ka refractive index likhna ya water ka..i am confused

n1 refractive index of glass


Apny Q2 ko kasy solve kia,?? will you show plz

@Shabir, Question 3 mai simply light color ki pehli value ko surface color ki phli value se multiply krna hai or baki 2 ko b isi method se.

mtlb light color ki phli value ko surface color ki phli, same dosri value ko surface ki dosri value sy multiply krna hy and so on for value three,,?
