Hi.

 

I think the WaveFront object file parser could be improved.

For example the vertexPattern is given   

private static Pattern vertexPattern = Pattern.compile("(v( (\\-){0,1}\\d+\\.\\d+){3,4} *\\n)|(v( (\\-){0,1}\\d+\\.\\d+){3,4} *$)");

So it expects to find a vertex in the form

v followed by three or four numbers made up of: an optional -, followed by digits, followed by ., followed by more digits.

 

but some wavefront files don't match this pattern in some cases i.e. they don't have a decimal point

v -1.5 0 1.5

 

Perhaps there is a better pattern based around eg

v(

    ( (\\-){0,1}\\d+\\.\\d+ )

  | ( (\\-){0,1}\\d+          )

  ) {3,4}

or similar?

(-{0,1}\d+\.{0,1}[\d]* *){3,4}

 

Maybe?
