Hello

I'm using the library proscene and I just install the new version of processing : v2.08.

I do not know why but the mouse events fail. The escene can be rotated, but I can't move it, or make zoom.

Anyone else would happen?

Any solutions? It is a very useful library and would love to continue using

Thanks and regards!

The next code works properly with Processing v2.0b7

and fails with Processing v2.0b8
2. import remixlab.proscene.*;
3. Scene scene;
5. void setup()
6. {
7. size(1000,500,P3D);
8. scene = new Scene(this);
9. }
11. void draw()
12. {
13. background(128);
14. fill(20,40,60);
15. box(100);
16. }

Hello

After work with processing now I'm trying processingjs.

I have not found any good forum about processingjs by now.

I have a few questions and was wondering if anyone

on the forum has worked with javascript processing and could help me.

I'm trying to make an application in wich coexist the 3D and 2D.

To do this I mounted a PGraphics object and render over it the 3D scene.

Later over the P2D general scene I draw the GUI (controls, interface...)

That method worked perfectly in my conventional processing, but when trying to run with the program js processing blocks me and stops responding to mouse events.

By testing I can see that everything is broken by introducing lighting

pg.lights ();

strokeWeight() not work either in a P3D scene (This is another problem)

Has anyone had the same problem and found a solution?

It would be helpful for me

thanks

This is the code: It works in processing but not in processingjs
2. PGraphics pg;
4. float tx;
5. float ty;
7. void setup()
8. {
9. size(500,300);
10. pg = createGraphics(500,300,P3D);
11. }
13. void draw()
14. {
15. //3D scene
16. noLoop();
17. pg.beginDraw();
18. pg.background(32,64,128);
19. pg.lights();
20. pg.fill(255,128,32);
21. pg.stroke(0,0,0,255);
22. pg.strokeWeight(2);
23. pg.translate(250,150,0);
24. pg.translate(tx,ty,0);
25. pg.box(100);
26. pg.endDraw();
27. image(pg,0,0);
29. //2D scene
30. fill(0,255,0,64);
31. stroke(0,0,0,255);
32. strokeWeight(2);
33. rect(0,0,100,30);
35. text("This is 2D",5,20);
36. }
38. void mouseDragged()
39. {
40. tx = tx + (mouseX - pmouseX);
41. ty = ty + (mouseY - pmouseY);
42. redraw();
43. }

Picking in PGraphics

Hello.

I'm trying to use the picking library, but I have a problem and I don't know how to solve it.

I have this code that works correctly:

import picking.*;

Picker picker;

void setup()

{

size(500, 500, P3D);

picker = new Picker(this);

}

void draw()

{

camera(-20, -20, 50, 0, 0, 0, 0, 1, 0);

rotateY(10);

background(255);

lights();

picker.start(1);

fill(32,64,128);

box(10,10,10);



picker.start(2);

translate(20,0,0);

fill(255,0,0);

box(10,10,10);

}

void mouseClicked()

{

int id = picker.get(mouseX, mouseY);

println(id);

}

But in my program I need to draw in a PGraphics object. Then the picking doesn't work.

How could I fix this???

This code doesn't work

import picking.*;

Picker picker;

PGraphics render;

void setup()

{

size(500, 500, P3D);

render = createGraphics(500,500,P3D);

picker = new Picker(this);

}

void draw()

{

render.beginDraw();

render.camera(-20, -20, 50, 0, 0, 0, 0, 1, 0);

render.rotateY(10);

render.background(255);

render.lights();

picker.start(1);

render.fill(32,64,128);

render.box(10,10,10);



picker.start(2);

render.translate(20,0,0);

render.fill(255,0,0);

render.box(10,10,10);



render.endDraw();

image(render,0,0);

}

void mouseClicked()

{

int id = picker.get(mouseX, mouseY);

println(id);

}

Best regards and thanks in advance
