I wanted to know how to calculate start and end angle of an arc with the following data known:
1. Starting Point
2. Ending Point
3. Center of the arc
Any information related to this will be very helpful.
Thanks in advance!
It's basic geometry. You have a center point, you have two end points. Define a vector from the center point to each of the end points. Calculate the angle from each vector with respect to the reference axis (X axis, I believe). The only thing that might be tricky about it is if the function you are feeding these values into needs them in a range of zero to 360 degrees, or -180 to +180 degrees.
Thanks a lot !
As you said my main intention is to understand what values to be allocated in 2D arc structure. As you mentioned, will it be zero to 360 degrees, or -180 to +180 degrees.
