Gold 4.1 - How do we update vertices? Software: Away3D 4.x

theMightyAtom, Sr. Member Posted: 18 July 2013 08:04 AM Total Posts: 669 Just downloaded Gold 4.1 release. The updateVertexData() function has been removed, and I can’t find another way to manipulate vertices manually. Any ideas? UPDATE: It’s still there, but you have to cast the member of the subGeometry array as a SubGeometry. Guess it was a vector before? `m.geometry.subGeometries[0].updateVertexData(tv);` becomes `(m.geometry.subGeometries[0] as SubGeometry).updateVertexData(tv);` It’s causing an error in length compared to previous release. I’ll look into the new structure and find a fix. I use the updateVertexData in alot of my work…
theMightyAtom, Sr. Member Posted: 18 July 2013 08:51 AM Total Posts: 669 [ # 1 ] I didn’t find a fix, and ended up rolling back. If anyone has a working example of a vertex manipulation in Gold 4.1.4 I’d be glad to see the code Perhaps there’s a much smarter way of doing this?
sentoplene, Newbie Posted: 18 July 2013 09:04 AM Total Posts: 25 [ # 2 ] Here’s the magic…. _subGeom = _mesh.geometry.subGeometries[0].cloneWithSeperateBuffers(); _vertexData = _subGeom.vertexData; _uvData = _subGeom.UVData; _normals = _subGeom.vertexNormalData; _tangents = _subGeom.vertexTangentData; _indexData = _subGeom.indexData; // do manipulations here var vtc:Vector.<Number> = GeomUtil.interleaveBuffers(_numVertices, _vertexData, _normals, _tangents, _uvData); CompactSubGeometry(_mesh.geometry.subGeometries[0]).updateData(vtc); Or you can use: `_mesh.geometry.convertToSeparateBuffers();` which will convert the CompactSubGeometries inside the geometry to SubGeometries, which will contain the ‘Oldskool’ vertexData, normalData etc. Hope this helps!
theMightyAtom, Sr. Member Posted: 18 July 2013 11:43 AM Total Posts: 669 [ # 3 ] Thanks a lot Sentoplene. I must have been sleeping in class, when did this all happen? Don’t suppose there’s any docs or an article explaining the structure? Cheers!

If you need to update the verts often (like on every frame), i think its faster to convert to the old subgeometries, and update the old way….. Signature sorry…i hope my actionscript is better than my english…

After Weld(); the same lighting as before... ››
