Ok, this is what I have until now:
with the points:
With that I got:
I used this formula to calculate Bézier Matrix:
With that, I got:
And then the matrix:
For Lagrange I have this formula:
And then got these results:
Which led me to this matrix:
As long as:
then I used these formulas:
(Is the order correct? How can I check it?)
And got these results:
-I am not sure if the order of the multiplication of the matrixes is correct. how can I check it?
-One thing that I noticed is: if you sum the elements inside the lines for the matrixes TL\<-M and TB\<-M, except for the last line, it will always result 0. Is it a property or something?
-And the last question: from the matrixes TB\<-L and TL\<-B I can get some equations. But how can I, from these equations or form the matrix, get the control points?
thank you again for your help,
