To use it in your own project, download the .scad and put it in your openscad library folder or in the same folder as the project you are using it in. Then at the top of your script just type :
We've also included this in Customizer! Include it in your customizers by typing:
Here'Âs a full list of the functions and modules included:
give this function a 3D vector in [x,y,z] format and it will return the length of that vector
function angleBetween_3DVector(u, v)
give this function two 3D vectors in [x,y,z] format and it will return the angle, in degrees, between them
give this function a 3D vector in [x,y,z] format and it will return a vector that points in the same direction but with a length of 1
function dotProduct_3DVector(u, v)
give this function two 3D vectors in [x,y,z] format and it will return the dot product of those vectors
function crossProduct_3DVector(u, v)
give this function two 3D vectors in [x,y,z] format and it will return the cross product of those vectors
function rotMatrix_3DVector(axis, angle)
give this function a 3D vectors in [x,y,z] format for axis and an angle in degrees and it will return a rotation matrix for the axis-angle rotation
function rotAxisAngle_3DVector(vec, axis, angle)
give this function an initial 3D vector and a 3D vector for the axis in [x,y,z] format, and an angle in degrees and it will return the rotated vector
function trackTo_3DVector(cur, tar, influence)
give this function an initial 3D vector and a target 3D vector in [x,y,z] format, then give it an influence between 0 and 1 and it will return an interpolated vector between the two vectors according to the influence
function random_3DVector(seed = undef)
calling this function without any parameters will return a random 3D vector. pass it a seed value to get the same "random" vector each time
vector = [10, 10, 10],
root = [0, 0, 0],
color_from_magnatude = true,
magnatude_range = 100,
radius_from_magnatude = true,
manual_radius = 1,
res = 16
this module will draw a colored arrow to represent a 3D Vector.
root controls where the vector starts from.
magnatude_range defines the vector length that will result in a purple arrow. Vectors approaching 0 length will be red.
radius_from_magnatude controls if the arrow gets fatter when it is longer.
manual_radius controls the radius if radius_from_magnatude is set to false.
res is the number of facets around the arrow.
my_vectors = [[10,10,10],[-10,10,10]],
root = [0, 0, 0],
this module will recursively draw a chain of colored arrows end to end to represent a list of 3D Vectors.
root controls where the vector chain starts from.
iterations_left controls how many more recursions will occur, this parameter will self populate and only needs to be exposed because of how recursion works in OpenSCAD. Don'Ât set this unless you have a good reason to.
