How To Access Dop Geometry

[DoctorBuzz]

Hi guys,

how can I access point and primitive position, point and primitive attributes, etc. in a DOP simulation?

You can access DOP geometry information using any of the expressions you use to access SOP geometry information like point(), prim(), and so on. All you need to know is how to specify DOP geometry in the first parameter of the expressions (the one that normally specifies the SOP node). To do this, use a string with the format:

dopnet:objname/dataname

dopnet is the path (relative or absolute) to the DOP Network.

objname is a specification of the object you are interested in. This can be an object name or an object id number.

dataname is the path to the geometry data attached to the object. If no dataname is given, "/Geometry" is assumed.

Thanks for your answer mtucker,

but i mean how to access it with HDK...

Thanks anyway

Hi there;

Take a look at the source code for the ODE Solver DOP on Sourceforge - you'll see it in there.

Oops. I guess I should have guessed that since this is the HDK forum

As Jason says, the ODE Solver code shows how to access the GU_Detail pointer from a DOP Object. The SIM_SolverHair example in the $HFS/toolkit/samples/SIM directory also does this. I'm assuming that once you have a GU_Detail pointer you know how to get what you want? If not, check the HDK documentation relating to geometry ($HFS/toolkit/html/geometry/index.html).

Thanks guys,

I'll look into the examples you suggested.

Thanks again for the support (as always on this forum)
