# Calculate Target Aspect Angle From Vector

This post categorized under Vector and posted on May 19th, 2019.

Ive been struggling with what I think should be a very simple problem. I know the current heading angle (say 15 deg) and given a target gameObjects transform I want to calculate the angle that I should rotate towards to face the target.But if you look at the components of the vector (x 20 miles y 20 miles) theyre both negative so the angle must be between -90 degrees and -180 degrees. If you subtract 180 degrees from your answer of 45 degrees you get 135 degrees which is your actual angle measured from the positive x-axis in the clockwise direction.I have many 3D planes. The thing that I need to know is the way of computing aspect angle. I hope I can compute the aspect angle by using the projected normal vector of each plane (my plane equation is axby-zc0 so normal vector of this plane is ab-1) to the XY plane.

I just want a vector pointing at a direction of a specified angle and for it to have a magnitude of 1 such is called a heading vector I believe. At least it is in the various game code I look at. At least it is in the various game code I look at.Calculate vector3 from angle Im currently making a camera but Im having trouble finding out a ventor3 from an angle. I want the camera to be able to rotate around my character.For 3D Vectors Axis Angle Result. This is easiest to calculate using axis-angle representation because the angle is given by acos of the dot product of the two (normalised) vectors v1v2 v1v2 cos(angle) the axis is given by the cross product of the two vectors the graphicgth of this axis is given by v1 x v2 v1v2 sin(angle).

The calculator will find the angle (in radians and degrees) between the two vectors and will show the work. Show Instructions In general you can skip the multiplication sign so 5x is equivagraphict to 5x.16.06.2008 Calculate the graphicgth of each vector. Picture a right triangle drawn from the vectors x-component its y-component and the vector itself. The vector forms the hypotenuse of the triangle so to find its graphicgth we use the Pythagorean theorem.74 %(83)Aufrufe 21M
