How did u write that last matrix...aren't we supposed to make separate calculations for each coordinate point.. Also can we treat it like a cuboid for landing coordinates...pls explain
Assumption: we are dealing with a line. For the line with end points A(a,b,c) and B(d,e,f), first scale them both according to s. [scaling] Then fix one end point of the scaled line to either A or B, and find the new co-ordinates of the other endpoint. [translation] Then simply rotate the line along x, y and z axis with angles alpha, beta and gamma. [3 rotations] If the 5 transformation matrices from above steps are P, Q, R, S and T respectively, then the required composition transformation matrix is given by = T x S x R x Q x P In order to get co-ordinates of the final line, multiply this product with the homogenous representation of each co-ordinate either one-by-one, or together(as shown in end of video) - your wish. PS- Fixing one endpoint at (0,0,0) allows you to bypass the translation step, but then it's not a general solution.
I have no words to appreciate your effort brother
dekh toh le corrent hai ya nhi
Abey kaunsi effort 9 min ki bc
@@hritavsinghsolanki8893 galat hai kya
Please explain the -sin theta in rotation about y axis, how does change with respect to different axis
at 5:23
R=Rx*Ry
multiplication is wrong please do check
Ya right , first Ry * Rx
No, it will be Rx*Ry but matrix multiplication answer is wrong @@lalitk
@yashvashishth8644 ....yes bro 👍
nice video thanks sir

5.25 time , the matrix ry 1st row sin45= 1/√2 why did u write -1/√2 and also 2nd row 1st value in resultant matrix is 1/2 why it is 0
most teachers on YT dont have knowledge of what they teach!
bhai pura din se same doubt hain...achanak tera comment dekha..or bach gaya ...thanks
bhai
09:08 bhaiya iss part mean 4X8 wale matrix ki 4th row ko 1 kyu liya hai ....matlb baki jagah 0001 kar rahe hai iss mean hi kyu sabko 1 rakhna hai??
its a rule to write like that, while writing coordinates we have to write 1111 instead of 0001
Simply super to understand the concept...
How is the multiplication of Rx . Ry is correct??
please make one video for segment and animations
Apne time pass kar diya
kya matlab
I love you bro this help my eaxm
Awesome 😎👍
Notes kha milege?
Thank you❤❤❤❤
Clockwise and anticlockwise bhi rhega na
Hello ,
Why we take 1 at last element ?
TO MAKE MATRIX HOMOGENOUS
Thank you brother
Derive the transformation matrix for scalling an object scalling factor s in a direction defined by the direction angles please tellme (solution)

Rx. Ry is it Wright here????
No galt hai wo matrix
No
wrong in matrix multiplication
Thanks bhai
Before exam video is running in 2x speed 😂😂😂
It is already in 2x speed 😂
5:29 R matrix wrong hein viwers correct it.
App please thoda dherre dheere samjhye bhut speed ha
Matrix multiplication at 5:25 is Wrong
nice
Rx.Ry elemental multiplication ki jagah matrix multiplication karna tha its wrong
Sir aapne jo rotation matrix likhe first question me vo toh puri glat h
sir thode aur question karado
Batana hi hai to achese aaram se btaya kro
Fast me hi dekhna rahta to video ki speed 1.5x kr ke dekhe rehte
Notes dalte jao n plz
matrix multiplication is wrong
Bhai 2d sai thi teri video bhai isme ghanta pta chlra kuch
Reduce your speed dude!
🤣
And I'm watching it on 1.5x
@@amitranjan9814 me on 2x 😂
Thankyou
