Is there any specific reason that 2d labels are leafs?
And is this "Leafs could not have children" needed at all?

Thank you

Tried with visibily array - but without selection array - works. But with "removeSelectedVertices" - triangles are removed from current Mesh, but points are left in PointCloud, should it be removed too? I tried to remove it manualy: ccGenericPointCloud *deletedCloud = pCloud->createNewClou...

I will try,
but isn't it a duplicate for second method parameter "CCLib::ReferenceCloud* selection"?

if visibility array is used - i do not need "CCLib::ReferenceCloud* selection" - right?

Yes it is gready, for mesh with ~1M triangles - i used 50M memory (with assumtion that 1 vertice could be shared between max 12 triangles). ccMesh *pMesh = static_cast<ccMesh*>(Entity); ccGenericPointCloud *pCloud = pMesh->getAssociatedCloud(); ... CCLib::ReferenceCloud *selectedCloud = new CCLib::R...

for example i have cube and sphere in one mesh, i want to split them to separate meshes (cube in one, sphere in other). (simple selection with polyline is not sollution for all cases) In my algorithm i need: to get triangles that share same vertice (has same summit). and after collecting all triangl...

added: works fine. no colors or scalar fields needed. (point cloud is from imported *.stl mesh)

Tried, it works, new point is added to cloud, and i can create 2d label on that point: if (Cloud->reserve(Cloud->size() + 1)) { Cloud->addPoint(Points[2]); cc2DLabel *middlePoint = new cc2DLabel(); middlePoint->addPoint(Cloud, Cloud->size() - 1); middlePoint->setDisplay(Cloud->getDisplay()); middleP...

Yes, already tested :)
It has "black" background, why?
Why not like labels 3D name - without background?

Could i add point to existing cloud? I get execution error on code like this: if (Cloud->resize(Cloud->capacity() + 1)) { Cloud->addPoint(Points[2]); <-- this line throws error ... } should be resize called or reserve? or new must be created? And how to get index of last added point?

1. Thank you, it works, great. 2.problems with labels already encountered: a) labels could not be moved in DB tree (they depends on it's point cloud) b) label could not exist independently, new point cloud has to be created. and spheres for this situation are just great :) Could i make modifications...
