given a startPoint, range and bearing, can I calculate the other point?

I want to calculate the other point in a Cartesian Coordinate system. How can I do that?

Thanks!

Could you define the terms a little more ?

1) By "range", do you mean "distance" ?

2) by "bearing" , do you mean direction, and if so, what is your input ? An angle ?
Directional unit vector ?

3) 2D or 3D ?

So would this algorithm be correct:

X2=X1+(cos(angle)*distance)
Y2=Y1+(sin(angle)*distance)

Thanks!

Yes, it is correct.

There are some widely published equations that will give you what you are looking for... here are the 3D ones ;)

Code:

---

sx = (sin(theta_xz) * r * cos(theta_yz)) + cx
sy = (r*sin(theta_yz) ) + cy;
sz = (cos(theta_xz) * r * cos(theta_yz)) + cz

---

sx, sy, sz are the coordinates you are trying to calculate. cx, cy, cz are the coordinates you are at, r is euclidean distance (range in your terms). theta_xz is the angle in the xz plane (sweeping from z to x), and theta yz is the angl in the yz plane (sweeping from z to y).

Thanks!

I suspect that the problem is you're using degrees as your unit of angle, which is not what the cos function is intended for.
