Hi I am trying to create a visual experiment in Adobe After Effects
I have an ellipse.
All values of the ellipse are available however I am unsure how to rectify them mathematically to find a point on the ellipse.
If I have the major/minor axis, starting point [0,0], horizontal ellipse
a) is it possible to find a point along the ellipse
b) is more information required to solve
c) How can I determine a coordinate where a tangent from central point would cross the ellipse?
c) i. Using either an angle input e.g. angle = theta, coordinate =?
c) ii. OR using an equation for the graphed ellipse curve from minor to major axis and using it to determinate a coordinate of a percentage distance from the starting point.
??
Can anyone help me please
Thankyou for your time considering this!
