Convert global coordinates to local coordinates
Given a vector expressed in global space and a mesh, how can I get the position of this vector within a mesh local space? Or, alternatively, how can I get a parent position within a child local space? Update: Just figured it out... It is simply vector.subtract(Mesh.getAbsolutePosition()), right? Update2: Ok it's not... Because it doesn't take in account the mesh rotation.
Think I came up with a solution: var m = new BABYLON.Matrix(); mesh.getWorldMatrix().invertToRef(m); var v = BABYLON.Vector3.TransformCoordinates(vector, m);Is that right? What I did is simply an inverse of local->world transformation process.
