hi,
i want to record rect's with angular stroke caps within a 3 dimensional space.
therefor i'm using P3D renderer and this for recording:

1.     PGraphicsPDF pdf = (PGraphicsPDF)beginRaw(PDF, numbr +"file.pdf");
       pdf.strokeJoin(MITER);
       pdf.strokeCap(SQUARE);

but it's eiter round or has a gap at the stroke corner:(
the additional attributes, as:

1.     pdf.strokeCap(SQUARE);
2.     pdf.strokeCap(PROJECT);

don't work with a 3D renderer:((

what can i do please?

setting up a larger square underneath does not help either, since i work with colored alpha values, but opaque strokes...
