Hi! I'm trying to get into Houdini procedural pipeline, and as you may admit, the learning curve is a bit steep for novices. Hope that you can help me to break the ice. I came from Grasshopper for Rhino and I'd like to ask questions based on examples of a workflow I'm used to. So here is the first example: Is there any way to see data structure like It's seen here in Houdini? Im doing copy spheres over the grid, but the data behind is total black box. I don't know what order is there etc (except point indicies displayed in viewport) So, how can I access data structure in a handy way like in my example? Second example: As you see, it's very simple to see and manipulate data, but I have my mind twisted with Houdini approach. How to understand it and get the same level of transparency of data-manipulation? I tried to make a stamp expression to drive spheres radius, but it's more "let me guess!" than "ok, I understand what I'm doing" so what I did was make sphere size variable in stamp inputs with value $PT/10 and placed it in size parameter of sphere node with stamp expression (stamp("../copy1","sphereSize",0)) And obviously it's not that intuitive. How to get what $PT returns? What else can I use inside values inside copy Stamps? Is there any way to make the process more transparent? I lurked through the documentation, but didn't find clear explanations of this topic. So How should I drive each row with desired value for spheres scale? The last example is this one: As you can see, here I generate a series of numbers based on point list length and plug them into sphere radius parameter. The base points of spheres now have flat data structure, so no more rows. Data matches as it is, each value is applied to each sphere. How can I reproduce this in Houdini? How to generate series of numbers? (start, step, count) How to generate ranges of numbers? (domain (from 1 to 20), divisions) But the main question is still, how to make the workflow that transparent? How to see what happens to data, how to manipulate it in that flexible way (sliders, output panels, etc)? I cannot believe that there are no options to make the process clear and intuitive, I believe that I'm a total noob and need your help! Thank you in advance!

Hi everyone, This is my first post, so thank you for taking time to help me out. Any pointers are very much appreciated. I am currently trying to model a paneling surface in hou, by this I mean - I am trying to define one shape, that then is copied onto a surface and repeated several times to cover the whole area. In order for this to work, the defined shape, will need to bend and deform to match the surface. You can see an image that illustrates this here. http://1.bp.blogspot.com/_xQcRvrIdDbs/TFlZGcj4QGI/AAAAAAAAABw/KRujR4J9i1Y/s1600/attractor.gif This is done fairly easy in Grasshopper (rhino plugin) - in there, each shape's bounding box is used to deform the defined surface. Here is some info on Panelling tools, the plugin used in grasshopper - http://wiki.mcneel.com/_media/labs/panelingtools.pdf Please let me know if you know any tutorials that use this, even if its not exactly the same - or any hints! thanks so much. Frederico
