I sent my submission to codingchallenge@lavausergroup.org back on November 16, 2005. I was hoping for a confirmation that the submission was received. I saw another post saying their email to codingchallenge@lavausergroup.org bounced (for them). I sent a followup email to you later that week (but before the deadline) and I haven't heard anything. Just wondering if it was ever received. Thanks, MGulley

Michael: You mention in the challenge "the goal is to accomplish this challenge using the default picture control that comes with LabVIEW. If you know of a better native way to do this in LabVIEW, go right a head." My version of LabVIEW 7.1.1 has several PICTURE FUNCTIONS that (according to the LabVIEW help documentation) are "NOT INCLUDED IN BASE PACKAGE". I am not avoiding use of these picture functions in my coding efforts. I hope these are not the "IMAQ TOOLS and VIEWERS" you prefer us to avoid.

If you have 2D array of grayscale values, you can display the array in an Intensity Graph display. If you set the colormap of the Intensity Graph to ramp from black-to-white, (and enable interpolate colors), the data will be displayed as a gray image.

This is more work than one would think at first glance. Aren't all software projects I've been thinking about texture mapping the image onto a surface and using the 3D plot to display it. The plan is to warp the surface to simulate the wave motion. So far I have been able to get RGB images displayed in the 3D display (but only a flat surface, in 2D right now). The big challenge there was the colormap, and I'm still not pleased with the display. It looks like several colors are being clumped into one even though the image looks very nice in the PICTURE display. Anyone have any thoughts on how to get better color mapping in my 3D plot?
