Find angle between two vectors from 0 to 360
WebIf the % operator acts like remainder in your language (retains sign), you can simply add an extra 360 instead of defining a modulus function: a = (a + 540) % 360 - 180 As stated above, this only works for angles within 360 of each other, which may often be the case. Otherwise: a = ( (a % 360) + 540) % 360 - 180 – RedMatt May 20, 2024 at 16:05

WebSo if it only measures smallest angle i will not know whether i need to add or subtract an angle. measure the angle between vector 0-1 and 0-3 measure the angle between vector 0-1 and 0-2 0-2 need to 90 degrees anticlockwise to 0-1 0-3 need to be 270 degrees anticlockwise to 0-1 (90 degrees clockwise) WebApr 17, 2024 · Every method I've tried has given me a value between 0-180 degrees but doesn't tell me whether it was a clockwise or counter-clockwise rotation. For example: If I hold my forward vector in a variable and then turn counter-clockwise 45 degrees and use that as my second forward vector, I'm looking for -45 or 315 degrees as the output, not 45.
WebDec 28, 2012 · To get [0°,360°] without a case distinction, one can replace atan2 (y,x) with atan2 (-y,-x) + 180°. – MvG Dec 13, 2016 at 18:54 3 Noooooo don't ever take acos of a dot product! That's mathematically correct but horribly inaccurate in practice. WebApr 15, 2024 · The arctan2 function is given both x and y of the vector so that it can give an angle in the full range [0,2pi) and not just [-pi,pi] which is typical for arctan. The angle you are looing for would be given by: arctan2 (b_y, b_x) - arctan2 (a_y, a_x) The result may be a negative angle, but at least it will go from vector a to vector b.
WebMar 31, 2024 · We have two points on a circle in 3D space, as well as the center point. How can we calculate the angle between the vector from the center to point one and the vector from the center to point two, with the calculation starting from vector one counter-clockwise to … WebThe angle, , is the angle between the two vectors. Cos θ = Cos(θA − θB) = Cos (θB − θA) The square of a vector is considered a dot product with itself. We can represent the magnitude of a vector as a dot product.

WebFor a vector that is represented by the coordinates (x, y), the angle theta between the vector and the x-axis can be found using the following formula: θ = arctan(y/x). What is a …
The formula is giving the angle of two vectors a and b from 0 to 360 degrees, in left wise direction for any value of the vectors coordinates. For xa=ya=0 and or xb=yb=0 the result is undefined.

With this formula, you can find the smallest angle between the two vectors, which will be between 0 and 180 degrees. If you need it between 0 and 360 degrees this question may help you. By the way, the angle between two parallel vectors pointing in the same direction should be 0 degrees, not 180.
