hint() not working with GLGraphics within beginDraw()

in Contributed Library Questions • 2 years ago

Hi...

I'm using GLGraphics as my renderer, and also as a OffScreenBuffer and TextureWindow...

When I try to place hint() within my graphics, buffer, I'm getting an error...

Example:

canvas.beginDraw();

canvas.hint(ENABLE_OPENGL_4X_SMOOTH);

canvas.stroke(255);

...

canvas.endDraw();

Error:

PApplet$RendererChangeException

Console:

Exception in thread "Animation Thread" processing.core.PApplet$RendererChangeException

at processing.opengl.PGraphicsOpenGL.hint(PGraphicsOpenGL.java:538)

at bombIR.style(bombIR.java:441)

at bombIR.mouseDragged(bombIR.java:414)

at processing.core.PApplet.handleMouseEvent(PApplet.java:1821)

at processing.core.PApplet.dequeueMouseEvents(PApplet.java:1748)

at processing.core.PApplet.handleDraw(PApplet.java:1642)

at processing.core.PApplet.run(PApplet.java:1530)

at java.lang.Thread.run(Thread.java:680)

( style() is the function where this code sits, called upon mouseDragged() ... )

Specs:

P5 1.5.1

OS X 10.6.8

Java 1.6

hint() in GLGraphicsOffScreen won't work. If you want antialiasing in your offscreen buffer, create the buffer like this:

canvas = new GLGraphicsOffScreen(this, w, h, true, 4);

Perfect, wasn't sure, but this these additional arguments work great. Sorry I didn't explore the reference more in-depth... but thanks for the answer.
