The lxp.py module#

Summary#

RayPath

Framework representing a singular ray path.

LightPathFinder

Define an interface to read LPF files.

wavelength_to_rgb

Convert a given wavelength of light to an approximate RGB color value.

ERROR_IDS

Intersection types indicating an error state.

NO_ERROR_IDS

Intersection types indicating a correct ray state.

Description#

The lxp module contains classes and functions to simplify the interaction with ray data.

Ray data is provided as lpf file. LPF files contain a set of simulated rays with all their intersections and properties.

Module detail#

lxp.wavelength_to_rgb(wavelength, gamma=0.8)#

Convert a given wavelength of light to an approximate RGB color value.

The wavelength must be given in nanometers in the range from 380 nm to 750 nm. Based on the code from http://www.physics.sfasu.edu/astro/color/spectra.html

Parameters:
wavelengthfloat

Wavelength in nanometer between 380-750 nm

gammafloat

Gamma value. By default : 0.8

lxp.ERROR_IDS = [7, 8, 9, 10, 11, 12, 13, 14, 15]#

Intersection types indicating an error state.

lxp.NO_ERROR_IDS#

Intersection types indicating a correct ray state.
