this is actually for computer programming.
I'm trying to show a line which plots the course taken by a ship. It's in space so drag etc are not an issue but it can continue to accelerate.
I felt initally the answer was to take the end point and figure out the angle between the current...
I blieve the mid point in space of arbitrary triangle formed by points A,B,C
is the point at which the line
A -> midpoint(B,C)
B -> midpoint (A,C)
C ->midpoint (A,B)
meet
(i also think C is redundant, that where A to mid and B to mid cross is basically the mid point of
the whole...
basically i have a problem where i am rotating 1 vector to be parallel to another
i get the axis of rotation by the cross product of the 2 vectors
the angle by the arctangent of the magnitude of the axis and the dot product of the 2 vectors
however
arctangent2(magnitude(axis) ...
So i know the equation of a plane.
Ax + By +Cz = D
Normal is the normal vector to the plane.
A = normal.x
B = normal.y
C = normal.z
p1 and p2 are 2 points on the line (which will intercept a plane at some point)
the .x and .y and .z refer to there respective components of the...
Oh i understand a vector rotates around another vector but to me at least axis is short for the vector around which something rotates. I believe I solved the dilemma but thank you!
This isn't actually a homework question, i'm programming something, it's just what should be fairly simple math i'm just not certain how to do it.
Assume I have a normalized vector which points directly up {0,1,0}.
I also have another vector X.
I'd like to rotate vector X along the...
I'm not sure if this is the right forum.
I'm actually trying to solve this for a computer program
given shape A and shape B i'd like to rotate shape A so a given face is parallel to the nearest face of shape B
