Away3D Forum Cannot update Vertex Data

Hi all, I don’t understand why I cannot update vertex data of a mesh with this code:

var originalVertexData:Vector.<Number> = myMesh.geometry.subGeometries[0].vertexData;
var newVertexData:Vector.<Number>;
for(var i:Number=0; i<originalVertexData.length; i++){
    newVertexData.push(originalVertexData[i] += 0.5);
   }
myMesh.geometry.subGeometries[0].updateVertexData(newVertexData); 

This code throws an exception “Call to a possibly undefined method updateVertexData through a reference with static type away3d.core.base:ISubGeometry”

Any idea?

May be

(myMesh.geometry.subGeometries[0] as SubGeometry).updateVertexData(newVertexData);

Thanks a lot, Lexcuk! With few adjustments your code works:

var subGeo:CompactSubGeometry=(myMesh.geometry.subGeometries[0] as  CompactSubGeometry);
subGeo.updateData(newVertexData);
