1.4.04. IMAGE SAMPLER
This exercise uses the colour values of a random image to define the radii of the circle field. Rather than controlling the domain of the image directly in the Image Sampler button we reparameterise the sample domain by remapping it to a domain from 0 to 1 in both the x and y direction.
1. Define a series of points
2. Remap the arbitrary sampling values to domains from 0 to 1 in both the x and y directions
3. Use the Image Sampler to sample the colour information (values from 0 to 1)
4. Multiply with 255 to RGB values and connect to a shader
5.Use the colour values to define circle diameters for circles on the point grid
This exercise is using Grasshopper version 1.0.0007
