3D transparency issues..

rubin

For some reason when plotting 3D objects with semi-transparent shapes, the lines (strokes) are not visible..

for example:

    size(100, 100, P3D);
    translate(50, 50, 0); 
    rotateY(0.5);
    fill(200,0,0,50); // semi-transparent
    stroke(10);
    box(40);

how can I get the hidden lines to reappear?

size(100, 100, P3D);
translate(50, 50, 0);
rotateY(0.5);
fill(200,0,0,50); // semi-transparent
box(40);
hint(DISABLE_DEPTH_TEST);
noFill();
stroke(10);
box(40);
