Do you want to draw the ellipse as a curve in 3d?
Or do you want to draw the natural generalisation of an ellipse to a surface in 3d?
ok here is the problem,
I need to draw a ellipse in 3d space, what i have for the ellipse is its r1, r2 (a, b) distances from center i also have an angle at witch the ellipse is inclined, delta.
Here is what i got in 2d for the ellipse:
x = a * cos(t)
y = b * sin(t)
what I'm obviously missing is the third dimension, any help is greatly appreciated. Thanks in advance.
