Hello, I wrote a file which can use isosurface to draw mathematical equation.
I'm satisfied with it's result and want to share it here.
I explained it below.
It has some global variable. Include a "PixelPerUnit" for scaling the diagram.
So the graphic (unit of length) will not be affected by rendered image size.
Another variable is "CenterOfCoordinate". It can be used to place the coordinate
origin on rendered image, you can set it as <400,300> or <1,1>, etc.
The macros is used to create some objects like grids, axes, and the mathemaics
equation graphics which you want to draw. It is very simple. But pay attention
to the "_layer_number" on every macro. The object with the number 1 will behind
the object with this number 2.
