Create a BEZIER SURFACE in MATLAB || TUTORIAL

Great! Do a similar video on B spline and NURBS please. Thank you

[@dulanjanaperera988]

Thanks for this. Very helpful. You provide all the details. Thanks again.

This is helpful! Please my question is what if you to apply this a geometry of a cuboid for instance in 3D , do you need all the 3D coordinates of that cuboid or how do you select these control points?

Obrigado! Thanks!

hii,, i am trying to do this with 3*101 points. how can I do it?

THANK YOU!!!!!😀

Hi, im trying to make this work for 5x5 - 25 points . how can I do this please ? it keeps writing me : Index in position 2 exceeds array bounds. Index must not exceed 3. Error in bezier_curve (line 44) xBezier = J(i, :)' * K(j, :) * x(i, j) + xBezier;

[@prot0form775]

If you are going to change the number of points, then uPTS and wPTS should be updated, instead of 3 (like in the video) write 5. And also, the arrays x, y, z in the video are 3x3 (or uPTS x wPTS) this means that in your case they should be 5x5 arrays. 4:15

@@prot0form775 Thank you ! I made it. The task for me here is to make an animation of different Bezier surfaces. Do you have any idea how to make it, please ? Thank you!

I'm tying to do it this for 4x4 control points and 20x20 cells but it gives me this error "Unable to perform assignment because the size of the left side is 1-by-4 and the size of the right side is 1-by-40."

[@prot0form775]

That could be a number of things. In what line is this error happening?

[@bhattner1]

Why can't we simply eliminate the nested for loop by writing the equations in matrix form: x_Bez = J'*x*K; y_Bez = J'*y*K; z_Bez = J'*z*K;

[@prot0form775]

You can't? I'm pretty sure you can do this on Matlab! It was made for matrix operations! :D
