Relative points

[joey o.]

I need to know the method(s) needed to find any given point inclusive of a circle.In other words I want to be able to refer to any point inside a circle as the center and make it behave as so.The circle will be drawn many times and the center must be able to change.I'm going to use this for a spinning sphere whose axis can be changed from user control.Anyone know where to start?
Thanks

Well, your second try was heared

I don't know how you want to do this exactly, but I can give you some hints. Use Sin and Cos to get the coordinates of an angle:

-
Dim A as Single

For A = 0 to 10 Step 0.01
PSet(Sin(A), Cos(A))
Next
-

You don't have to use 10 as maximum and 0.01 for step, I just had no time to look for the exact values. It has something to do with Circle = 2*Pi and 1° = Pi/180.
Hope this helps...

Every program can be reduced to one instruction which doesn't work.

Thank you,
Thats a lot of help. If anyone could add anything I'd be greatfull.

Joey,

If you know the initial co-ordinates (x,y,z) of the sphere and its radius (r) then for any point within the sphere (x1,y1,z1) the vector length between (x,y,z) to (x1,y1,z1) must be <=r
give me time and i may remember how to calculate vector lengths!!!!
