UniformRays

class raytracing.UniformRays(yMax=1.0, yMin=None, thetaMax=1.5707963267948966, thetaMin=None, M=100, N=100)

Bases: Rays

A list of rays with uniform distribution.

Parameters:

  • yMax (float) – Maximum height for the rays (default=1.0)

  • yMin (float) – Minimum height for the rays (default=None). If no value is assigned to this parameter it will be -yMax.

  • thetaMax (float) – Maximum angle for the rays (default=pi/2)

  • thetaMin (float) – Minimum angle for the rays (default=None) If no value is assigned to this parameter it will be -thetaMax

  • M (int) – Number of points that are defined for the height of rays

  • N (int) – Number of rays for each point

Examples

>>> from raytracing import *
>>> nRays = 1000 # Increase for better resolution
>>> minHeight=0
>>> maxHeight=50
>>> minTheta=0
>>> maxTheta=0.5
>>> # define a list of rays with uniform distribution
>>> inputRays = UniformRays(yMin=minHeight, yMax=maxHeight, thetaMin=minTheta,thetaMax=maxTheta, N=nRays, M=10)
>>> inputRays.display()
