◆ m_bValid
| bool imstk::OctreePrimitive::m_bValid = true |
Flag to keep track of primitive validity During tree update, set it to true if the primitive is still contained in the tree node that it has previously been inserted to and: 1) The depth of current node reaches maxDepth, or 1) The primitive straddles over multiple children nodes thus it cannot be passed down further to any child node
