One more problem.. Do let me know if this post doesnt belong to this category.. If so, den which category it belongs.. Coz am writing c++ programs to solve it... Anyhow, Pls refer to the image diagram attached along this post..
You will find 5 points.. I need to calculate points a, b, c and d.. SO i thought i would begin by finding points a, d
lengths (Pa) = (Pd), is not constant.. it may vary every time.. it is called "along boundary length".. So, for a given along boundary length, i need to find these two points a, and d, with respect to P in such a way that,
l(Pa) = l(Pd) = along boundary length
First way i thought was to find the tangent(shown in green), of "along boundary length" and get two end points.. from these two end points i can draw a line which will intersect the arc, and i can get values of "a" and "d"... But now i feel this logic is having some fault..
Now am stuck up.. My ultimate goal is to find values of points a, b, c and d for given set of inputs:
1. Point P
2. along boundary length l(Pa), l(Pd)
3. off boundary length l(ab), l(cd)
Any way to get this solved..??
Thanks in advance
