Isosurfaces

Hi,

found a really cool link but due to my learning status, I'm not really sure how to implement these expressions.

Please could anyone show me the way on one example? Thanks in advance.

 

Cheers

You have to type these expressions into the Implicit Fuction field of the Isosurface node. But before you can simply copy and paste these strings you need to define some custom functions like the the guy who wrote them. To define these custom functions need go to Edit > Aliases and Variables and there into the Expression tab. Copy and paste the following into the textfield:

#deg sin
float sind(float val) {
    return sin(deg(val));
}
#deg cos
float cosd(float val) {
    return cos(deg(val));
}

Hit Apply Changes and these two new expression function should be available.

Now in SOPs you can lay down an Isosurface node and copy and paste the expression into the Implicit Function paramenter-field. Make sure to adjust the Bound and Division parameter accordingly.
