PHP Art
I have, for some time, been working on developing a fully-capable graphing calculator with PHP, and to put together the graphing interface, I have been exploring the GD library. Upon seeing all the geometric functions and drawing tools available, I decided I had to fulfill my artistic ambitions with this tool, so I created a black-and-white portrait of one of my favorite musical artists, Phil Collins. The code for it is posted below. I know it's not organized nor perhaps most efficient, but it creates an image that I'm happy with.

imagepng($image);
imagedestroy($image);Now, I did use Microsoft Paint and its infinite wisdom to assist with approximations of beginnings and endings of certain "polygons," and the rest was estimated and tweaked over and over. I'm wondering, is there any future for PHP art in your opinion? I know a much better rendering could be done with an actual Photoshop software or similar product, but I was so pleased with this method.

Hi Kurtis,
That is a nice picture!
I wonder, can you use your data to create a Google Chart - perhaps a type of scatter plot or maybe a venn diagram?
I think your method could be useful with user input to create/alter an image dynamically - I'm not sure what alternate methods are available.
Your image is more "graphic" than "photorealistic" so I would think there may be "graphic" uses (comix etc).
Good luck with the Brickfish competition!

Yeah, it's definitely easier to create a graphic effect because everything is so "straight-line." It is possible to create smoother edges and even shading, but it would take even more work. Who knows, I may try it out.
Using user input to alter images is definitely what I'm working toward; this was simply a personal experiment.

That is why I suggested the Google Charts scatter or venn diagrams, using rounded blobs instead of linear elements.
Actually, I think you can mix marker shapes, some round, some square...
I guess this is really left-field!

The main thing I dislike about trying to graph things this way is that pixel positions are based from the top left corner (as all images do), meaning that the point (max,max) would actually be displayed in the bottom-right corner instead of the top-right corner like in a traditional graph. It just takes a few computations to x- and y-values to make it look right, though. It definitely can be frustrating to the mind, though.

That is really cool. It's impressive because you got closer to the metal and used something a lot lower-level than Photoshop.
You could also apply non-destructive effects using GEGL. Don't seem to be any PHP bindings for that though.
