hi, i have a plugin where i create clones along points or polygons of a mesh. this works fine for still meshes, deformed meshes and PLA animated meshes, but not if the mesh is deformed by joints.
any ideas what is responsible for this?

thanks for any input.
cheers,
ello

How do you access the deformed mesh? Usally you have to perform a Current State To Object to obtain the deformed mesh.

I am using this:

  
//get the linked object  
BaseObject* baseMesh = ToPoly((PolygonObject* )(bc->GetLink(BASEMESH,doc)));  
PolygonObject* cloneOfBase = NULL;  
if (baseMesh->GetType()==Opolygon || baseMesh->GetType()==Opoint)  
{  
cloneOfBase = static_cast<PolygonObject*>(baseMesh->GetClone(0, NULL));  
}  
else  
{          
cloneOfBase = op->GetAndCheckHierarchyClone(hh,baseMesh,HCLONE_ASPOLY,&dirty,NULL,FALSE);       
}

You can't simply use the PolygonObject. You must first perform a Current State To Object. This is done with SendModelingCommand(). GetAndCheckHierarchyClone() on the other hand should take care of it when the linke dobject is not a polygon object. Does it work if the linked object is not a polygon object and deformed by a deformer?

yes, it works.. but with joints you need to have a polygon object. so i need to use currentstate to object.. i'll try it out

thank you for the hint

Hi, I got it working. However, i have now a memory leak and i dont know what i need to free?
Using MCOMMAND_CURRENTSTATETOOBJECT returns an AtomArray and the SDK tells me that i need to free it afterwards. GeFree seems not to work here..

thanks for your input..

Another similar problem occurs when i clone objects that are animated by joints.
how can i clone objects which are animated by joints and apply positions and rotations to them??
do i need to use MCOMMAND_CURRENTSTATETOOBJECT in this case, too? this could get performance hungry for a bunch of clones...

thanks for any further input.

Yes, you need to use MCOMMAND_CURRENTSTATETOOBJECT in this case too. Whenever you need to access the deformed mesh you have to use MCOMMAND_CURRENTSTATETOOBJECT, at least in cases where you can't be sure that all caches are build. This is the case in GetVirtualObjects().
