Whoa, that was fast. Ok that explains what it does in easy terms. Thank you.

The first line has <<2); instead of the diamond operator and the following img tag

edge was previously generated trough
byte edge = (byte)(vertexLocations[i] >> 8); where vertexLocation is a ushort from the lookup table. Since i am not sure what to do with ushort, i took the next bigger datatype which is an int. Don't know if thats valid.
