Hi,

I am trying to access the zbuffer of a Scene in Processing 2b6.
The idea is to port this project to processing v2.

It seems that the object FloatBuffer hasn't got the array zbuffer anymore.
So I tried with the commented code that tries to acces the zbuffer using OpenGL:


1. PGraphicsOpenGL pogl = (PGraphicsOpenGL) g;
2. FloatBuffer zbuff = FloatBuffer.allocate(1);
3. pogl.gl.glReadPixels( mouseX, mouseY, 1, 1, GL.GL_DEPTH_COMPONENT, GL.GL_FLOAT, zbuff);
4. float z = zbuff.get();

Hi,

I am trying to access the vertices of a PShape loaded using the function loadShape.
The PShape renders correctly but I dont know how to access its vertices, even trying this simple code:

1.     public void setup(){
          
           size(640, 720, P3D);
          
           obj = loadShape("teapot.obj");
          
           System.out.println(obj.getVertexCount());
          
       }

gives me a null exception. But the PShape obj is generated . The null exception is generated at the getVertexCount() call.
I am working with Eclipse.
Is there a way to access the vertices of obj?

Thanks!
