∏=circumference/diameter
∏=3.141592

Circumference of a Circle = 2∏* radius
 

sin(angle)=O/H
cos(angle)=A/H
tan(angle)=O/A

degrees=radians*(180/∏)
radian=degrees*(∏/180)

√H=A²+O²

x2-x1=length of a line

Calculating the length of an arbitrary line

length=

What are Radians?
One radian is the angle of the arc created by wrapping the radius around the circumference.

degrees=radians*(180/∏)

radian=degrees*(∏/180)
 

x²= x¹*cos(angle)-y¹*sin(angle);
y²= x¹*sin(angle)+y¹*cos(angle);

If : Conditional Statements

eg.

if(a<b)
{
do something;
}

a < b [a is less than b]

a == b [a is equal to b]
! b [not b]
a != b [a is not equal to b]
a >= b [a is greater than or equal to b]
a <= b [a is less than or equal to b]

This script creates and rigs the shoulder, elbow and wrist controllers for a basic arbitrary arm pose (non t-pose).

Note : A huge thanks to Shih Ming Tay for showing me this rigging technique.

step 1. Download the example file below.

        download scene file (MAYA 8.5 .ma) (right-click and save file. Rename file with .ma extension)

step 2. Copy the code below in the MAYA script editor and run it. The fmArmRigger window will appear (see image below)
step 3. Enter name of the shoulder joint
step 4. Select the aim axis of the joint (there is a Toggle Local Axis Display button to help with this)
step 5. Click the Create Arm Rig button. Finished.

Try Mirroring the arm joints in MAYA and then applying the control rig with this script.
