Particle Initialization
Particles are initialized at random positions on the source plane with random directions according to particle-specific distributions.
Coming Soon
virtual void initNew(rayRNG &Rng) override {}
Initial Distribution of Directions
Coming Soon
virtual NumericType getSourceDistributionPower() const { return 1.; }
Data Containers
Coming Soon
virtual std::vector<std::string> getLocalDataLabels() const {
return {};
}
virtual void logData(rayDataLog<NumericType> &log) {}
