Online 3-D Function Grapher

Currently under development: A standalone application version of this 3-D Function Graphing Program, written in Flash Actionscript, much faster, essentially more capabilities, built-in function calculator and many more...
This tool graphs z = f(x,y) mathematical functions in 3D. It is more of a tour than a tool. All functions can be set different boundaries for x, y, and z, to maximize your viewing enjoyment.
This tool looks really great with a very high detail level, but you may find it more comfortable to use less detail if you want to spin the model.
Examples, Supported functions, Add to your site, BBCODE for Forums

Y Axis Minimum		X Axis Minimum		Z Axis Minimum
Y Axis Maximum		X Axis Maximum		Z Axis Maximum
Formular for f(x,y)

If you know of a really cool 3D function that you would like to send to me, I could add it here and put it up as the 3D surface curve of the month.
The X, Y, and Z axes are where they are for illustration purposes only. Mathematicians would switch the Y and Z axes with each other. Computer graphics people would have at least one of the axes pointing in the other direction, away from you.

This graphing tool support these functions

sin(), cos(), tan(), asin(), acos(), atan()
ln() - standard natural logarithmic
e - natual base
sqrt() - square root
abs() - absolute value
max() - maximum of two numbers
min() - minimum of two numbers
floor() - revious nearest integer
ceil() - next nearest integer
round() - nearest integer
