Color grid with x and y args to visualize effects of 2D transformations?
You can see my website at http://intumath.org/Math/Geometry/Projective%20geometry/projectivegeomet.htm l for an example of the kind of color grid I'm trying to plot. Again, I have to be able to transform this via standard matrices, in order to illustrate the basics of various transformations. So I need either the x and y arguments available, or else I need the t parameter available. Unless there's some way in Mathematica to apply transformations in matrix form directly to an image. Thank you again for any help. Chris Young cy56 at comcast.net
