So all you need to do is to show that as long as there is a k Vertex Cover for the graph constructed in the reduction, you have a satisfying solution to 3SAT. This is effectively the "only if" part to the proof that the two are "equivalent". How this setup proves that if there exists a k-covering, then the boolean expression in CNF is satisfiable. That there is a 3SAT satisfaction if and only if there is a k vertex cover in the graph constructed in the reduction step.Īssuming you are familiar with how the reduction is done, (if not ,refer to the document). IIVertexPaint vp = (bi.To show that Vertex Cover and 3SAT is "equivalent", you have to show Object objMod = ip.CreateInstance(SClass_ID.Osm, PAINTLAYERMOD_CLASS_ID) IIDerivedObject dobj = global.CreateDerivedObject(obj) Private static IInterface ip = global.COREInterface įor (int i = 0 i < ip.SelNodeCount ++i) Private static IGlobal global = GlobalInterface.Instance Private static IInterface_ID IVERTEXPAINT_INTERFACE_ID = _ID.Create(0x3e262ef9, 0x220e7190)

VERTEX ITAB 3 CODE
Here's all the code I'm testing with (using 2018.4) using System Unfortunately I'm still doing something wrong, I've put my test code into its own project and stripped it back but I'm still getting the same error now happens in IBaseInterface bi = mod.GetInterface(IVERTEXPAINT_INTERFACE_ID) If there is a bug there, I can report it. Vp.SetColors(node, vertColors) // fails here. VertColors.Insert(i, 1, color.NativePointer) For example, this causes 3ds Max to crash, but not sure if it is setup correctly. Then I was not able to figure out the correct way to set the color array using the ITab. For example, this executes, but not sure it succeeded to set appropriate parameters: vc = .Create() The UI seems to have a number of other options than what the interface class has. But I do not have enough experience with this (even on C++ side) to know how it should work. Once the interface object is set, then the methods can be called. IIVertexPaint vp = (bi.NativePointer) as IIVertexPaint
IBaseInterface bi = mod.GetInterface(IVERTEXPAINT_INTERFACE_ID) object objMod = coreInterface.CreateInstance(SClass_ID.Osm, PAINTLAYERMOD_CLASS_ID) ĭobj.AddModifier(mod, null, 0) // top of stack I explored this a bit and think I have the solution to get the interface object. This is often an indication that other memory is corrupt.Ĭan anyone help with what I'm doing wrong ? Message=Attempted to read or write protected memory. IIVertexPaint vp = (IIVertexPaint)tMod.GetInterface(global.Interface_ID.Create(0x3e262ef9, 0x220e7190)) // IVERTEXPAINT_INTERFACE_ID IModifier tMod = (IModifier)ip.CreateInstance(SClass_ID.Osm, global.Class_ID.Create(0x7ebb4645, 0x7be2044b)) // PAINTLAYERMOD_CLASS_ID So far I've either got the existing modifier from the stack maxscript or maxplusĪs a test I'm trying to set vertex colors using the VertexPaint modifier, would like to achieve a less destructive workflow than collapsing stacks and setting color values etc.
