yFiles' viewer framework is able to switch between high-detail and low-detail rendering strategies.

yFiles' realizer classes EdgeRealizer and NodeRealizer are responsible for providing implementations of the two strategies. Method

public void paint(Graphics2D)

is responsible for high-detail rendering and method

public void paintSloppy(Graphics2D)

for low-detail rendering.

Graph2DView's paintDetailThreshold property determines when to use the "regular" high-detail rendering and when to switch to sloppy painting. By default, for zoom levels below 30% sloppy painting is used. (Setting this property to 0 effectively disables sloppy painting.)

Regular, i.e. high-detail, rendering of standard yFiles node realizers:

Sloppy, i.e. low-detail, rendering of the above node realizers:

Regular rendering of standard yFiles edge realizers:

Sloppy rendering of the above edge realizers:
