20 sep 2020 · The dot product doesn't give you the angle difference. It gives you the cosine of the angle difference multiplied by the magnitude of both vectors.
Hey All, I’m trying to compare a cube’s up vs worldspace up to understand what side it’s rotated on. I’m simply using Vector3.Dot(transform.up, Vector3.up). I thought this would give me 1 if the cube’s not rotated, -1 if it’s upside down and 0 if it’s on it’s left or right side. Worth noting, I’m only rotating on one axis (X) so only have 4 sides I need to worry about. However, I’m getting really weird numbers. Sometimes it’s above 1 or below -1. And at 90 degrees on it’s side I can get anyth...

I got a dot product that ranges from - 1 to 1. I need it to be 0-360 degrees and when hitting 360 it should be reset to 0. The closest thing I got to was something like this. But when reaching 360 it don’t resets (as expected) but lerping to 0 then back 360 and so on. The final value I need is a 0-1 but degrees works as well. Any ideas how to do this? // dir is 1 or -1 float angle = Vector3.Angle(v1, v2); float degrees = angle - (angle * dir);
9. Using Vector3.Dot for Direction Facing Calculation - Unity Discussions
12 mrt 2013 · The dot product is equal to the cosine of the angle between the two input vectors. This means that it is 1 if both vectors have the same direction.
This is not a scripting question directly related to a problem, but more related to myself trying to understand the way Vector3.Dot works. In following an example to detect if a player is facing a target, the lines of code that were used had a Vector3.Dot. Vector3 dir = (target.transform.position - transform.position).normalized; float direction = Vector3.Dot(dir, transform.forward); This was not explained very well as to how it was working so I decided to start digging through the net for an...

13. I need a help with Dot Product node! - Unity Discussions
19 dec 2020 · I understand Dot product node as a node that gives you the result of the difference in angles given from the input A and B.
Hi guys, shader graph newbie here. I have been following some of the shader graph tutorials from youtube and once again! having hard time understanding some of the nodes used. I understand Dot product node as a node that gives you the result of the difference in angles given from the input A and B. (if the angle difference between the two node is zero, it gives you 1, using cos values) So on the example above, I have plugged in vector 3 node to B, which gives you position of the vertex(...
