random_color_generator

utils/generators.py

Random color generator.

The random_color function is useful for generating a single random color. However, if you a dealing with a large number of objects the random_color_generator function can be used to generate a large number of random color values at once.

By default rgb color values will be generated. Greyscale values can be returned by specifying the type value.

Since this function returns a generator object you will need to wrap it in a list() or call the next() method on the generator. See the examples section below for usage.

syntax

random_color_generator(n)

parameters

n	number of color values

optional arguments

type	type of color value: `"rgb"` (default) or `"greyscale"`

examples

point cloud with random color values

def init():
   vertices = list(random_vertex_generator(500, -5, 5))
   colors = list(random_color_generator(500))
   Global.points = PointCloud(vertices, colors)

def display():
   lighting(False)
   Global.points.pointSize(2.0)
   Global.points.draw()

cubes with random greyscale values

def init():
   Global.points = list(random_vertex_generator(50, -10, 10))
   Global.colors = list(random_color_generator(50, type="greyscale"))

def display():
   lighting(False)
   for col, pos in zip(Global.colors, Global.points):
      color(col)
      pushMatrix()
      translate(pos)
      cube(0.5)
      popMatrix()
