new working sunflow library in processing
May 22nd, 2010, 1:01pm  
Hello,

After p5sunflow did not work anymore, I started to write an own wrapping class for processing which enables you to use the sunflow renderer in your sketches. My aim with the project was to create a much simplier library which can be later modified and extended.

You can find it on Google code:
http://code.google.com/p/sunflow4p5/

You can get the jar file from the Download tab. You may also be interested in a short guide in the Wiki section:
http://code.google.com/p/sunflow4p5/wiki/GettingStarted1

Please, take a look at that project. All feedback are welcome.
Thank you,
zzzzz

Very good news! Thanks a lot for doing this.

I am looking forward to test it (doing this morning). P5Sunflow used to be very limited on the lights and textures, actually there was no access to lights' setup. Are you going to try implement that?

This is really cool and I am definitely following it  Smiley

Hi Zaphod,

Your library was compiled with 1.6 and processing seems to only accept libraries compiled with 1.5

great news. it was about time for a new more advanced sunflow wrapper. the possibilities are great. like TM mentioned, there are a lot of features like, texture, lightning, material etc that could be implemented in future versions.

Has anyone got this working?

If so what version of Processing you are using and how are you importing the library?

nope, and I think the java version supported by processing won't let it work. But maybe I'm wrong...

Yes, I managed to get this working. I have currently installed processing-1.0.9-expert (without Java) and seperately installed Java Version 1.6.0_13. I got it to render the example scene, but I still have two issues.

1. The library is not recognised by processing when I put it in the libraries folder. So I'm not able to import the library from the menu and I don't know the import statements for it, assuming they would work anyway in this case.

Current work-around: I installed the files into the code subdirectory of the sketch. This works.

2. The scene renders fine. But after it is done, the window turns black again. I don't know why this happens. Adding noLoop() didn't solve the issue. Here is the output from the console.

Anyway, great to see work on a new sunflow library. With some more information and/or development this is a very welcome addition!

Cool, for the library to show I renamed the jar sunflow4p5.jar.
(Would be nice to have it work on 1.5 tho)

Thanks TM. I renamed the file and now it's showing all right Smiley

The import statement is: import hu.spidron.sunflow.*;

The second issue still persists, does anybody else have this problem and/or a solution?

I tried this with the original version. You guys can try it and see if it works.

Try creating a PGraphic image and then use this as the renderer

Code:

 import hu.spidron.sunflow.*;


PGraphics _a;
void setup(){
size(300,300,P3D);
_a = createGraphics (600,600, "hu.spidron.sunflow.NextSunflowGraphics");

}

void draw(){
_a.loadPixels();
_a.beginDraw();

//insert code here

_a.endDraw();
_a.updatePixels();
image(_a,0,0);
}

I tried your code andrewowaun. The result...

A second window is opened with the size of the PGraphic and the title "Sunflow v0.07.2". The image renders correctly there. However the image is not drawn to the PGraphic, so it does not appear in the main window. With this method noLoop() does work, so you can appreciate the image longer once it's done (instead of a black screen). But save and saveFrame only save the empty main window. With this method it also re-renders, but instead of the same normal image a kind of blue-ish version is overlayed on top.

That's great amnonP5.

you can add this to void keyPressed() or right before noLoop()

The beauty of PGraphics is that they behave just like the main IDE so _a.save("test.png"); works

For example
Code:



void pgsave(){

_a.save("sunflowrender.png");

// OR
//if you can make the PGraphic the same size during setup and ...

//loadPixels();
//arraycopy(_a.pixels,pixels);

}


Now just call it before the noLoop();

Code:


void draw(){
_a.loadPixels();
_a.beginDraw();

//insert code here

_a.endDraw();
_a.updatePixels();
pgsave();
PImage _c = loadImage("sunflowrender.png");
image (_c,0,0);
noLoop();



}

That code doesn't work because the PGraphic itself is empy. Even though the PGraphic statements are effective for drawing to the sunflow window somehow, it still is another window and not a PGraphic as usual. Tried all your code, but to no avail unfortunately.

However, with the regular example code I managed to save the correct sunflow output from the main window before the screen turns black. So that's good.

To summarize, I can either use the main window, save it correctly, but it ends in black screen and only runs once. Or use PGraphic-method resulting in second external sunflow window without any way (so far) to save the output, but with this method the code keeps running and the result is displayed on screen.

@Zaphod

Where's the Source, Luke?

Roll Eyes  >>> Found the source:  inside the jar

There is much to be done, and I'd love to help.
