Member Data Documentation

direction

Vector3 G3D::Surfel::Impulse::direction

Unit length facing away from the scattering point.

This may either be an incoming or outgoing direction depending on how it was sampled.

magnitude

Color3 G3D::Surfel::Impulse::magnitude

Probability of scattering along this impulse; the integral of the non-finite portion of the BSDF over a small area about direction.

The magnitude must be on the range [0, 1] for each channel because it is a probability.

The factor by which incoming radiance is scaled to get outgoing radiance.
