Instance Method

sampleFields(at:)

Samples all of the field nodes in the scene and returns the summation of their forces at that point.

Declaration

func sampleFields(at position: vector_float3) -> vector_float3

Parameters

position

A position in scene coordinates.

Return Value

The summation of forces exerted on that point.

Discussion

The sample is calculated as if a physics body is placed at that position in the scene. The body is assumed to have a mass of 1.0, with no charge or velocity. The body is affected by all field nodes.
