Im wanting to attempt something of a large equation and in axis formulas and wondering if anyone has tried something like this.
this is what it looks like in code with variables, it would get a bit longer (lol) without the variables due to repetition. Am I barking out the wrong tree?
for iy in 1 to 10 do
(
for ix in 1 to 10 do
(
y=iy
x=ix
Ymax = 10
Xmax = 10
Tx = x/Xmax
Ty = y/Ymax
X_1a= 0.0
X_1b= 5.0
X_1c= 0.0
X_3a= 20.0
X_3b= 500.0
X_3c= 10.0
X_5a= 5.0
X_5b= 200
X_5c= 10.0
X_2a= X_3a*0.1+X_1a
X_4a= X_3a*0.1+X_5a
X_2b= X_3b*0.1+X_1b
X_4b= X_3b*0.1+X_5b
X_2c= X_3c*0.1+X_1c
X_4c= X_3c*0.1+X_5c
Y_1= (1.0-Tx)^4.0*X_1a+4.0*(1.0-Tx)^3*Tx*X_2a+4*(1.0-Tx)^2*Tx^2*X_3a+4.0*(1.0-Tx)*Tx^3*X_4a+Tx^4*X_5a
Y_3 =(1.0-Tx)^4.0*X_1b+4.0*(1.0-Tx)^3*Tx*X_2b+4*(1.0-Tx)^2*Tx^2*X_3b+4.0*(1.0-Tx)*Tx^3*X_4b+Tx^4*X_5b
Y_5 =(1.0-Tx)^4.0*X_1c+4.0*(1.0-Tx)^3*Tx*X_2c+4*(1.0-Tx)^2*Tx^2*X_3c+4.0*(1.0-Tx)*Tx^3*X_4c+Tx^4*X_5c
Y_2 = Y_3*0.01+Y_1
Y_4 = Y_3*0.01+Y_5
zPos =(1.0-Ty)^4.0*Y_1+4.0*(1.0-Ty)^3*Ty*Y_2+4*(1.0-Ty)^2*Ty^2*Y_3+4.0*(1.0-Ty)*Ty^3*Y_4+Ty^4*Y_5
Point pos:[ix*10,iy*10,zPos] size:1

this code makes an array of points using a modified bezier equation in 3DSmax. Im also thinking of ways to shorten it but keep on wishing for arbitrary variables.
Is is possible to do this with VB, I've not tried my hand with that so I don't really know how difficult it would be.

sadly this renders non linear table correction useless. Back to the drawing board.
