Hello,

hello all,

I am still suffering from the rotation business.

I got a form consisting of many PShapes.

Now I want to rotateX it around its center.

Do I have to take the average x-pos and then reduce all x-pos by the average x-pos,
rotate and then translate it to the center?

The example shows a simple rotating cube.

Thanks!

hello!

in the forum the question arose how to let a 3D camera fly through a 3D scene with other flying objects.

I think of store a curved path to get 3D coors from and use them for the camera.

I tried several approaches but no good one....

curvePoint is quite cool
http://www.processing.org/reference/curvePoint_.html
but for a longer path I need to stick together several curves which seems to be very unconvenient.

I looked at curveVertex where I can add many points but there is no
curvePoint for this to read the points afterwards and put them into the camera.
Or is there?

Then I look into lib Shapoes 3D by quarks. Amazing. Especially
the
Bezier tube editor
http://www.lagers.org.uk/s3d4p/applets/s3d4p_beziertubeeditor/index.html

But I didn't find a way to get one single path instead of a tube.
A path I could read out and give into camera.
Any ideas?

FInally I thought of making a class CameraData and store the 6 camera
positions and then make an ArrayList of it and store the points into it
the camera has to fly to. But I realized it would look uncool because
with fixed points, the camera would fly with rough angles.

So my questions are:

• Any ideas?
• If I stick to the idea of class CameraData, how would I smooth out the movement? Or use damping here?
• Has this beeen done before?
  

"How would I smooth out the movement?" That was also a question here of course.

hello all,

I want to select a folder but make a default folder to start from?

At the moment the folder selector always starts at documents but I want to make it
start at D://Music

But how?


I am using this in my MP3 Player

Thanks!!

Chrisir

1. //
2. void chooseFolder() {
3.   selectFolder("Select a folder to process:", "folderSelected");
4. }
5. //
6. void folderSelected(File selection) {
7.   if (selection == null) {
8.     println("Window was closed or the user hit cancel.");

13.     getFolder();
14.     indexFile=0;
15.     getCurrentSong();
16.   }
17. }

I got a CocurrentModificationException with this:

(I am gonig astray anyway but now this...)

Who can help?

Would a backward for-loop thru the arraylist be a solution?

oh, I think break; instead of exit(); already helped, but why?

edited: oh, I meant return; instead of exit();  

Thanks!

hello!

I just try to use an arraylist as a function parameter

Possible?

I receive an error in line 12 not a known constr  lalala....

see bold part!

The idea is I want to create several local menues and since each of them can have different number of lines, each has an arraylist of lines..........

Or do I have to define a type ArrayList<LineInTheLocalMenu> ? How?

Thanks!

hello all,

I wondered if there's a local menu in processing that I can program using controlP5.
You know, when I right click with the mouse e.g. on an rect a menu that says "change color", "change size" etc.
Much simpler than in the image below of course.

Has that been done?

Many Thanks!

Greetings, Chrisir   

let's assume I have some text data I want to interprete as colors.

Let's further assume I want to put them into PImages via createImage. (This is not in the code yet)

How can I store a color there saying transparent?

Thanks!  Greetings, Chrisir

hello,

hello all,

I am looking for something similar to this:
The equivalent statement to get(x, y) using pixels[] is pixels[y*width+x].

only in 3D and other way round.

Let's assum I have a cube 3x3x3 and
value going up from 0 to 27.

I want to assign each cell in the cube to a number.
So I need a function value-> PVector

e.g. 23 -> 2,3,2 or so.

hello all,

this is a simple OPENGL-code, it worked in 1.51, doesn't work anymore....

can anyone help?

Thank you!

hi,

I am still thinking about a marble machine with tracks for marbles.

With a marble rolling down in 3D construct.

There is a system made of wood that I would like to program in processing:
http://www.cuboro.ch/de/Info/Produkte
(there seems to be an elevator system for the marbles they are proud of)

There are wooden blocks with tracks upon it, but also blocks with tunnels in it, even
blocks with 90° curves in or upon it.

When I program it, I want to run a marble through it, not as a proper physics engine but as data structure
that knows, where is the cube and where is/are its entry point(s) and exit point(s), so the marble can pretend to follow the right path and fall where it should etc.

I am not sure how to make a class for it.

I could have an ArrayList of all cubes and its pos, its type and its rotation.

There are I think 9 basic types like

• straight tunnel with straight track upon it (both same direction)
• straight tunnel with straight track upon it (90° to each other)
• straight tunnel with curve to the left upon it,
• straight tunnel with curve to the right upon it,
• crossing of two tracks upon it (+) and tunnel leading in on the side, coming out of the button  ( \ )
  
• etc.

How can I make my class so, that the rolling marble comes into the block, knows its new direction and in which cubes it goes next and from which of its sides? This must be some kind of a rule set.

How can I make connections between two tracks / cubes?

Later the marble machine could be shown visually 3D with the rolling marble, camera follwoing it, marble making noises when rolling or falling.
Later still there could be a visual editor to make and save your own marble machines.

Thanks for any thoughts on that data structure thing!

hello,

I just realised that this doesn't work:

1. boolean fileExists(String fileName) {
2.   File file=new File(fileName);
3.   println(file.getName());
4.   boolean exists = file.exists();
5.   if (exists) {
6.     println("true");
7.     return true;
8.   }
9.   else {
10.     println("false");
11.     return false;
12.   }
13. }

How can I determine the existence of a file on the hard drive?

Cheers,

hello all,

I have performance issues within a for-loop that lies in a recursion.

Can I just ask some questions?

I learned while searching for "performance" in the forum the compiler is pretty bright and makes good decisions.
Obviously, I declare everything outside loop and recursion to save it time.


1st question: Does the data type make a difference in terms of speed?

Let's say

• PVector []

versus

• int[]  // for x   (or float)
• int[]  // for y
• int[]  // for z

or say

• PVector []

versus

• MyOwnClass[]

Any difference?


2nd question: Does the usage of Strings and + need a lot of time?

• I heard usage of + with String is not recommended - what does the merging with StringBuilder look like?

3rd question: Allocated memory?

• When I make the memory usage higher in my IDE and compile, does the exe-file (the application) under Win 64 knows the higher memory usage? Or how can I enforce it? (or doesn't it matter since Win 7 provides memory dynamically?)
  

4th question: Are there other pitfalls?

• What are other pit falls?

Thank you!

hello all,

I have a question regarding 2D arrays like

1. int [][] someStuff;

Is it possible to say

1. arr1=arr2;

(filling arr1 with the same values as arr2)?
From my tests: yes.

Or use arrayCopy?

Is it possible to say

1.               if (!arr1.equals(arr2))
2.                 println("arr1 != arr2 ----------------------------");

?
From my tests: no.
But how can I compare them? In a for loop?

And finally regarding call by ref / call by val:

1.               arr1=makeMove(arr2, x1, y1, dir );

seems to change arr1 and arr2 (when arr2 is changed in makeMove and then returned), so it is a call by ref?
I think yes.

I know, this is all very basic and has been asked before but I couldn't find it.

Thanks!

Chrisir

hello,

Does this work:

1.     holdUp = holdRight = holdLeft = holdSpace = holdS = false; //should set all to false...

or are we happier with:

1.  //should set all to false...
2.     holdUp =  false;
3.     holdRight =  false;
4.     holdLeft =  false;
5.     holdSpace =  false;
6.     holdS = false;

thanks!

as a metaphor

The equivalent statement to "get(x, y)" using pixels[] is "pixels[y*width+x]".

I want it the other way round: When I have "a" being a continous number for all cells (up to 100 in a 10x10 grid):
What is x and y derived from "a"?


a would be a = y*width+x

Hello,

I was just pondering another thread

http://forum.processing.org/topic/is-pgraphics-the-only-way-to-solve-the-memory-problems-in-processing

when it occured to me whether PGraphics works in 3D? And if PGraphics and PeasyCam work together?

I think it does not (for both).

But I can call createGraphics with P3D as a renderer and I can call

1. pg.line(40, 40, 100,
2.   40, 40, 40);

with 3D lines / coors.

But the result with peasyCam shows a 2D image which rotates.

My hope was to have a 3D tree e.g. that in stored as a PGraphics.

Is that possible?

Thank you!

Hello all,

I don't understand PVector.angleBetween or it doesn't give the results I expect.

I thought it would work like in a circle: you hand it the middle of the circle as PVector and another point on the circumference as PVector and you got the angle (the same thing that with cos and sin would give the difference of x and y).

But I don't think it does....

So what does it really do... and what can I do to achieve what I want?

I post my Code to clarify. I know it gives you rad and I convert it to degrees but still...
