I know nodes own the geometry, but how can I differentiate between the types of geometry coming in? For instance, the sphere SOP has different primitive types (mesh, nurbs, bezier,polygon etc) so the representation in the SOP node , the geometry which is retrieved through gdp should have the geometric type info in it?? I guess I should look into the GEO and GU classes??
thanks
thanks

You want the objects in the scene to maintain their scale when the camera zooms in? Is that what you are trying to achieve?So objects wouldnt look bigger?Sorry just trying to understand what you are trying to say

Just coded my own custom operator after all the trouble …I wrote a PyramidSOP. Heres the screenshot..Nothing great, but its a small glory!

Finally it works!!! I think it was a build problem. I downloaded the latest build and I had no problem. . Thanks for everything guys especially edward.

Does having a previous version of Houdini affect compiliation? I had version 9.0 which I uninstalled before installing version 9.5.241.

I use a Geforce Go 7300 on my laptop running Windows vista and I dont have any problem running Houdini 9.5.241. As Steven asked which build are you using? Do you have any network path settings on ur PC? You need to be a lil more specific.

Ya I am using the 32bit cl. I tried the same Houdini build (9.5.241) and compiled the SOP_Star and SOP_Flatten on my XP machine.
Config
MS Windows XP Professional
Version 2002 Service Pack 2
Machine config
Dual Processor Pentium 3.2Ghz, 3.19Ghz, 2.0Gb RAM
Nvidia 7800GTX
The SOPs dont work on this machine as well. Are there any environment variables to be set? Where do I get the daily builds? When I execute the Flatten SOP, I get the following crash log

I didnt get achance to try out on Vista again, but I'll do what you said. Thanks for all the help btw. It cant be the problem with the code, since it has worked before on other users machines I suppose. So logically it has to be some configuration or compilation problem??

L-systems is simple once you understand the underlying concept. Everything else builds on top of it. There is a premise and then rules. And then there are the symbols which turn the turtle(this is what actually draws on the screen) like + (turn right) - (turn left) and () repositioning the turtle etc. As far as I can see there is just one alphabet which moves the turtle forward(F) - correct me if I am wrong. So F in the premise would draw a straight line. FFF would draw a line 3 units long and F+F+F in the premise would draw a triangle and F+F+F+F draws a square. Now rules can be used for two things like node rewriting (geometry replacement ) and edge rewriting (geometry appending) thats where additional variables can be used.
Node rewriting
Premise: F+F+F
Rule : F=F-F++F-F
This is a standard koch snow flake.
Edge rewriting
Premise:FX
Rule: X=-F++F-FX
What I have give here is 2D, but advanced operations allows the turtle to move in 3D and to branch and specify the lengths of each branches. Tree and planting modelling uses edge rewriting.

I have the 32 bit installer. Been pulling my hair out trying to figure out why the SOPs arent working. I am using Windows Vista. Can that be a problem? But Houdini is working fine, no hiccups. Its just the dlls of the custom SOPs. I guess its working for you. The dll size is 48kb (SOP_Star.dll). Is there any discrepancy in that?If any library is missing, then the size would be different right?

Yes I am using the latest Houdini 9.5.241. Funny thing is it is happening with three custom SOPs I tried (2 from the samples and one which I coded). I compiled them with hcustom. I am not using any external library. Just plain default code. eg: hcustom SOP_Star.C
So there cant be any improper linking problem.

Hi
I am using Houdini Apprentice 9.5 and was trying to do a bit of HDK programming. At first before coding my own SOP, I tried to compile one of the examples in the toolkit directory (StarSOP). It compiles fine and the corresponding dll is generated and Houdini Apprentice loads the dll as well ( I get the SOP in the tab menu in Geometry) but the moment I select it and press Enter, the application crashes (Segmentation fault). Has anyone tried this before? I dont have any idea why this happens. Is it because I am using the Apprentice edition?
I compiled the code using hcustom and not VC++.
thanks
