The default renderer very smoothly supports zooming in on ROUND line endcaps and joins while maintaining their roundness. P2D and P3D, however, assume that any strokeWeight less than one won't have visible endcaps even when the scale factor blows them up to many pixels in size.
The following code runs fine with s = 600, i.e., no scaling. Change to s = 1, however, and the endcaps and joins disappear. Remove the P2D and both cases will stay smooth.
float s = 600;
void setup() {
size( 600, 600, P2D );
noFill();
scale( height/s );
strokeWeight( 0.2*s );
point( 0.3*s, 0.3*s );
strokeJoin( ROUND );
beginShape();
vertex( 0.6*s, 0.2*s );
vertex( 0.8*s, 0.8*s );
vertex( 0.2*s, 0.6*s );
endShape();
}
