Im trying to better understand using expressions to drive parameters and I wondered if anyone could push me in the right direction.
I am just using a circle SOP and a line SOP. I would like to have the distance value of my line sop driven by the circumference of my circle. Now I understand the maths.
* The circumference of a circle can be found by multiplying pi ¶ (which is equal to 3.14) by the diameter of the circle.
* If a circle has a diameter of 4, its circumference is 3.14*4=12.56
* If you know the radius, the diameter is twice as large.
So this would mean I would need to create 2 expressions in the radius channels which would then be added together and then connected to the line distance value. The result would be a line that is the length of the circumference of my circle.This is where I become unstuck with knowing how to apply this anyone care to help ?

Cheers for the insights ! but I do notice one weird thing when I use the insert tool to move the pivot point sometimes the geometry races off round the screen and other times the geometry remains in place ! maybe thats a bug in H9
Cheers

I knew it would be something simple. I did a search and did find something with reference to a right click menu on the transform icon !. As to the insert key working as the short cut for this ! guess I didn't type in the right word or words in the search eh !
Still odd though how I have to chase my object round the scene to snap the pivot point to the curve , surely my object should remain still!!!
cheers

Hi guys a picture says a thousand words , in maya I would use the inset key to move my pivot point thus letting me then snap my curve to a point. whats the work flow in Houdini for this ?.

Houdini is a pipeline in a box. Maya is a box that you have to build a pipeline for

Hi all
Is there a way to align a selection of points. I want to mirror some geometry and would like a group of points to be aligned along the x axis
Also is there a way to select a bunch of edges and create an edge loop ? cutting edges with polysplit is a bit tiresome.

When using the bricker function in H9 and H8 you get odd divisions Is there anyway to fix this , esp at the corners and at other random places.

Is it possible to go dive inside a shipping shader like the polka dot using the vex editor ? I just wanted to see how some things had been achieved to use in other shaders

For those of us who do not live in LA or London would it be possible to record/ produce some training material based on the lectures being given by sidefx

This as a subject would get my vote for sure. As to H9 from those advertised classes mention H9 will be used.
Jeff keep up the great work !
