Formulas are compiled to GLSL and run on the GPU. The full generated source of the vertex shader is shown below.

Formulas are defined using a simple stack based language similar to the previous TA iteration. Commands:

• * multiply
• + add
• - subtract
• / divide
• s sine
• c cosine
• c tangent (mnemonic: "hypotenuse")
• t current time in seconds
• x current x value in radians
• m absolute value (mnemonic: "magnitude")
• n negate
• d sign (mnemonic: "direction")
