[C++][CustomOp] - UV Cluster update problem
Hi list, Recently I have encountered with the problem that I cant update UVs and Usernormals clusters on the mesh. Situation is here: I have a some custom op connected to some original geometry ( input ) and setted on the some result geo ( output ). Work is going in the operator update callback. Topology of the result geo is changeable and can has more of polygons than in the original one. It also has a UVs and usernormal clusters ( both created as "always completed" ) which must be resized respectivetly to the topology changes. But problem is that nothing similar to resizing simply doesnt happen, when I have a result topology with a greater number of polys and try to update clusters values with UVCls.Set ( const float * _pValues, LONG nbNodes ) - I get crash. And at this time, GeometryAccessor reports a valid nodes count. Furthermore, if I call UVCls.GetValues ( CFloatArray& ) I will get the size of CFloatArray is valid also. So, I cant understood what I am doing wrong or is it a bug. If topology is not being changed - UVs updates fine. I have also looked at this threads http://www.xsibase.com/forum/index.php?board=14;action=display;threadid=35564 http://www.xsibase.com/forum/index.php?board=14;action=display;threadid=41707 and seems like that my problem is the same. Are there possible workarounds ( even something like CCOMApiHandle ways ) ? Thanks, -Oleg
Re: [C++][CustomOp]
Thanks guys, GetSource() works well in my case. >>can't you use the OperatorContext and use either GetOutputTarget ? It's return the valid cref only in the Execute Command callback, but in the Operator Update I always get something very empty :-) Thanks, -Oleg
Re: [C++][CustomOp]
Hey Oleg, most of times, GetSource() with operators returns empty references in cpp. You can still try it, with some luck, you should get the operator itself and then by a call to GetParent3DObject() whhat you're looking for. jo 2012/5/1 Steven Caron > can't you use the OperatorContext and use either GetOutputTarget ? or > maybe use GetSource to get the operator itself and navigate up? > > i haven't tried it in c++ but a simple runtime SCOP with this in the > Update callback works... > > Application.LogMessage(In_UpdateContext.Operator.Parent3DObject) > # INFO : sphere > > s > > > On Tue, May 1, 2012 at 11:33 AM, Oleg Bliznuk wrote: > >> Hi List, >> a simple question about custom op.

Re: [C++][CustomOp]
can't you use the OperatorContext and use either GetOutputTarget ? or maybe use GetSource to get the operator itself and navigate up? i haven't tried it in c++ but a simple runtime SCOP with this in the Update callback works... Application.LogMessage(In_UpdateContext.Operator.Parent3DObject) # INFO : sphere s On Tue, May 1, 2012 at 11:33 AM, Oleg Bliznuk wrote: > Hi List, > a simple question about custom op.

[C++][CustomOp]
Hi List, a simple question about custom op. I have a custom op which can has either 1 or 2 input geometries and connected to polymesh of created geo as output target ( see screenshot ).I need to get name of the global parent ( X3DObject ) of the object on which this operator is applied ( "grid_FR" in my case ). The SDK says that I am unable to do it from the operator update callback, only from ExecuteCommand. So is there way to obtain this name without creating any additional properties\userdatas etc in the op update callback ? Something like this which works validly in executeCommand callback : Application().LogMessage ( "GLOB NAME: " + mainMeshObj.GetActivePrimitive().GetParent3DObject().GetName() ); Many thanks, -Oleg <>
