hi, can anyone explain me why the dynamicParticlesRetained-example has almost the same frameRate as the dynamicParticlesImmediate-example? i would have expected the retained-example to be much faster.

thanks

hi *,
i am trying to get a slider running in eclipse with the slider demo code out of the guido library.

result so far: no slider visible. the constructor gets called. the draw-function of the slider never gets called.

if i use the processing ide everything works fine.

processing version is 2.0.3

has anyone ever used guido out of eclipse?

am i missing something?
2. import de.bezier.guido.Interactive;
3. import processing.core.*;
5. public class Main extends PApplet {
6. Slider slider;
8. public static void main(String args[]) {
9. PApplet.main(new String[] { "--present", "Main" });
10. }
12. public void setup() {
13. size(1680, 1050);
14. Interactive.make( this );
15. slider = new Slider( this, 2, 20, width-4, 16);
16. }
18. public void draw() {
19. background(0);
20. }
21. }
26. import de.bezier.guido.Interactive;
27. import processing.core.PApplet;
29. public class Slider
30. {
31. float x, y, width, height;
32. float valueX = 0, value;
33. float min, max;
34. PApplet parent;
36. Slider ( PApplet _parent, float xx, float yy, float ww, float hh)
37. {
38. parent = _parent;
39. x = xx;
40. y = yy;
41. width = ww;
42. height = hh;
44. valueX = x;
46. // register it
47. Interactive.add( this );
48. }
50. // called from manager
51. void mouseDragged ( float mx, float my )
52. {
53. valueX = mx - height/2;
55. if ( valueX < x ) valueX = x;
56. if ( valueX > x+width-height ) valueX = x+width-height;
58. value = parent.map( valueX, x, x+width-height, 0, 1 );
59. }
61. void draw ()
62. {
63. System.out.println("draw is called");
65. parent.noStroke();
67. parent.fill( 100 );
68. parent.rect(x, y, width, height);
70. parent.fill( 120 );
71. parent.rect( valueX, y, height, height );

hi everybody,

the folowing demo code shows my problem.

i want to use controlp5 in a 3d sketch in processing 2.0.1

the problem is as soon as i instanciate the controlp5-class my fill colors get messed up.

in this example the right box should be red and not brown.

HELP :)

import controlP5.*;

ControlP5 cp5;

void setup() {

size(1024, 700, P3D);

cp5 = new ControlP5(this);

}

void draw() {

lights();

background(0,0,0);

pushMatrix();

fill(255,0,0);

noStroke();

translate(width*0.75, height*0.5, 0);

box(150);

popMatrix();

pushMatrix();

fill(0,255,0);

noStroke();

translate(width*0.25, height*0.5, 0);

box(150);

popMatrix();

}

hemesh library: import obj 3ds not working

hi everybody,
i am having lots of fun with the wonderful hemesh library from frederik vanhoutte.

in my last experiment i wanted to import a 3d model of a bottle:

http://www.turbosquid.com/FullPreview/Index.cfm/ID/582482

http://www.turbosquid.com/3d-models/3ds-max-water-bottle/412870

i tried to go via HEC_FromObjFile and i also tried HEC_From3dsFile, but i can't get it to run.

the call of the constructor just doesn't return:

mesh = new HEC_FromObjFile(sketchPath("Bottle.obj")).create();

no error message and no exception. the call runs forever till i kill the process.

tried it with other models, but that produced the same results.

am i missing something?

hi everybody,

in the p5 ide the following code behaves as expected. the red box is partially seen through the transparent grey big box in front of it.

when started out of eclipse just a grey box is produced. the red box behind it is not visible at all.

all in processing 2.02.

is this a bug or am i missing something?

any help appreciated.

import processing.core.*;

public class Main extends PApplet {

public static void main(String args[]) {

PApplet.main(new String[] { "--present", "Main" });

}

public void setup() {

size(640, 360, P3D);

}

public void draw() {

lights();

background(0);

stroke(10);

pushMatrix();

translate(width/2, height/2, -100);

rotateY(1.25f);

rotateX(-0.4f);

fill(255,0,0);

box(50);

popMatrix();

pushMatrix();

translate(width/2, height/2, 0);

fill(100,100,100, 100);

box(width, height, 10);

popMatrix();

}

}

no antialising in opengl on macbook pro with amd 6750m in bootcamped windows 7

hi,

i am having a problem with not working anti-aliasing.
i am using opengl-mode in processing 2.0b8 on a macbookpro with amd hd 6750m as graphics card. i am using windows 7 via bootcamp. this laptop also has an integrated graphics card which should never be active under windows. could it be possible that processing is using this inferior card for some reason?

i checked the forum but to no result.

this following testcode delivers me a sphere with no anti-aliasing.
any help greatly appreciated.

public void setup() {
size(1024, 768, OPENGL);
smooth(4);
}

public void draw(){
lights();
translate(width/2, height/2);
fill(100);
noStroke();
sphere(100);
}

P3D frameRate uncontrollable

hi *,
i have a sketch that is producing some animation. two animals consisting of particles and springs are moving over the screen. problem is: the framerate varies from 70fps to 300ps. whenever i start the sketch again i fet a highly different framerate. the variation does not happen because if other applications eating up my cpu/gpu power.

i am using toxiclibs physics. the sketch is running on a macbook pro with an ati 6750m as graphicscard. i am using windows as os. this macbook also has simple onboard graphicscard. can the jumping framerates result from uncontrolled switching between the simple card and the ati card.

any help appreciated

martin

i am using the newest processing version.
