algorithmic modeling for Rhino
Angle to Vector
Hello,
the following problem/bug(?) gives me a hard time. I want to convert a given angle (entered via a slider; range 0-360) into its corresponding vector. To do so, I use the sine(a) and cosine(a) functions, as follows:
sin(a) gives the y-vector
cos(a) gives the x-vector
Afterwards,I combine these values using vector xyz component to obtain the vector.
However, sin(90) returns 0.89.... and cos(90) returns -0,448... and not 1 and 0, etc.
What do I miss?
Thank you for your help.

Gna,
figured it out. Its using radians, so I have to convert the angle first.
sin(rad(x))
thx,
