Error when using P3D Processing 3

MoMo

down vote favorite Could you please help me I am trying to start drawing 3D shapes using Processing 3 Whenever the renderer P3D is used, I get the following Error

ERROR: 0:2: '' : Declaration must include a precision qualifier or the default precision must have been previously declared. ERROR: 0:30: '' : Declaration must include a precision qualifier or the default precision must have been previously declared.

The piece of code I am trying to run:

float x,y,z;
void setup() {
  size(200,200,P3D);
  x = width/2;
  y = height/2;
  z = 0;
}

void draw() {
  translate(x,y,z);
  rectMode(CENTER);
  rect(0,0,100,100);

z++; // The rectangle moves forward as z increments.
}

Thank you

try OPENGL instead p3d

??

Still getting the same error

Have you tried creating a P2D sketch. P2D and P3D both use OpenGL for rendering. If the error occurs in both then check that you are using the latest OpenGL drivers on your graphics card.

MoMo

The same problem with P2D. But I have tried Processing 2 and every thing was fine.

Then try reinstalling PS3

Chrisir

well, did opengl work in p2 or just p2d?

update graphics driver?

MoMo

yes it work in Processing 2. I have updated it but still nothing.

quark

It might still be worth updating your graphic drivers. It could be PS3 using additional features of OpenGL not supported by your drivers.

try OPENGL instead P3D

@Chrisir, even today haven't you realized that OPENGL became a mere alias for P3D once Processing 2 arrived? 8-| println(OPENGL == P3D); // false for P1, otherwise true.

I know, same
