ProtoFlux:Pi

π

*

Constants

The Pi node outputs the mathematical constant π.

Applications this can be used in:

• Geometry and Circle Calculations
• Rotations and Angle Calculations
• Wave Generation (combined with Sin)
• Physics Simulations (especially when dealing with circular motion, pendulum movements, or orbital mechanics)
• Procedural Generation (especially curves)
• Lighting and Shading (used in lighting models to calculate angles and intensities of light, reflections, and refractions)
• Animation Curves

If you need to use 2PI for calculations, instead of using the Mul or Add nodes, you can use the Tau node to do the same thing, streamlining your ProtoFlux.

Outputs

* (float)

The value of π, approximately 3.14159274.
