Modules

This module contains mathematical constants and strings that contain the various directories used by the program. Math constants: - PI - 2 PI - wp (working precision of the whole program). Default is double precision (64bit floats) Directories: - homedir. Root directory of this code - fileplace. data folder directory - resdir. holds the path to the directory that holds the parameter and other associated input files

Module contains each detector type which inherits from the base detector class. detectors detect photon packets colliding with the detectors.

This module defines the cartesian grid type (cart_grid) and associated routines.

The iarray module contains the variables that record the fluence. These are 3D arrays, with roughly the same dimensions as the cart_grid type. Jmean is the local fluence. JmeanGLOBAL is the global fluence grid. The global version is the one that is written to disk at the simulations end.

Contains the main program and scattering loop. Calls all other routine to setup, run and break down the simulation.

module implments the optical property abstract type and the types that inheirt from it abstract optical property type

Helper functions for parsing the toml input file

routine to parse the source table from the input Toml file.

This source file contains the photon type, all the photon launch routines for different light sources, and the scattering code.

module provides an interface to call random_numbers and various other random distributions======= !!This module defines a set of functions that return random numbers in different distributions. !!- ran2. Returns a single float uniformly in the range [0, 1) !!- ranu. Return a single float uniformly in the range [a, b) !!- randint. Returns a single integer uniformly in the range [a, b) !!- rang. Returns a single float from a Gaussian distribution with mean avg and std sigma. !!- init_rng. Seeds the internal random number generator with a reproducible seed.

Collection of helper functions for SDFs:

This module defines the signed distance function (SDF) abstract type and all types that inherit from it. The SDF abstract type defines the optical properties of an SDF (mus, mua, kappa, albedo, hgg, g2,and n), as well as a transform (4x4 matrix), and the layer ID code of the SDF. The SDF abstract type also provides an abstract interface (evaluate) which each inheriting function must implement. This evaluate function is the heart of the SDF implementation. Each individual evaluate is the direct implementation of that SDF, e.g. that function defines the mathematical SDF. For more information on SDFs, check out Inigo Quilez's website from which most of the below SDFs and transforms have been taken.

This file sets up some simulations variables and assigns the geometry for the simulation.

Contains the routines that handle reflection, and refraction via the Fresnel equations.

Vector class module. Defines a vector type (x, y, z) and associated operations on vectors and other types.
