Calling createShape() directly will use the Applet renderer.
If this renderer is set to be of type P2D, the resulting shape seems to ignore any z value set to it's vertices.
I'm guessing that this shape contains some optimizations aimed at 2D rendering.

There should be a warning when using this kind of "flat" PShape on a P3D renderer.
Maybe even a different PShape class to make it foolproof.
Also, it would be great if 3D PShapes could be created without needing to reference a PGraphics3D that is in the "draw state".

Here's a piece of code to replicate the issue:

PGraphics g3D; PShape shape; void setup() { size(800, 600, P2D); g3D = createGraphics(width, height, P3D); //g3D.beginDraw(); // uncomment to fix flatness shape = createShape(); // change to g3D.createShape(); to fix flatness //g3D.endDraw(); // uncomment to fix flatness shape.beginShape(LINE_STRIP); shape.vertex(0, 0, 0); shape.vertex(200, 0, 0); shape.vertex(200, 0, 200); shape.endShape(CLOSE); } void draw() { g3D.beginDraw(); g3D.background(255); g3D.translate(width / 2, height / 3, 0); g3D.rotateY(((frameCount % 400) / 400.0f) * TWO_PI); g3D.shape(shape); g3D.endDraw(); image(g3D, 0, 0, width, height); }
