I'm making an android app with P3D renderer, but it's nearly uncontrollable because it's terribly slow. What I'm doing is making use of dozens of vertexes to draw some weird polysurfaces. The interaction here is just dragging vertexes to adjust its position, therefore changing the whole shape, and rotating the screen to see every face of the shape. I've tried not specifying render in size() method, but it says like the renderer does not support screenX(), screenY() and screenZ() functions. Those functions are crucial because you are to drag points in 3D space with 2D interface, so I cannot get rid of those parts. Is there any better way to deal with 3D in android mode, or are any better renderers out there?
BTW, it works just great if I run the sketch in JAVA mode. And the android device I'm testing with is NEXUS 7 with Android version 4.4.
Thank you in advance, and let me know if additional information is needed.
