as you know i already tested it. :)
If you find some time, msg me and i tell you how it worked for me.

Cool. Will check out the new stuff.

To render to the sketch's folder instead of Processing's application folder one can replace a line like this...

1. sunflow.render("box.png");

...by something like this...


1. sunflow.render(sketchPath + "/box.png");

Btw. is there any good source on how to use shaders with sunflow. After all the ao shader is the only on I can get the result I've expected. The glass shader for example gives me a black screen in most cases.

Two good links I've used a lot are the Sunflow Wiki and this Sunflow Shader overview.

With regard to your problem, it's probably because ao is a self-illuminating shader, while the others are not.

The solution would be to add lights and other stuff to your scene to get some reflection going.

Amnon is right. AO is always visible. The other shaders need light. So the best way to start is turning on the sunsky light. And then bit by bit testing and adding other lights. And putting a white plane on the top (y=1000) for example puts a nice indirect light.

I think those issues have be addressed on the website lateron. Another thing,  when using sunsky light, the background does not works and one has to set it by oneself. The sunflow library has some of those special points.

And maybe playing with the glass values. Creating a for-loop that creates a matrix of spheres and increases the values. Then you'll see wich fits best. Similar to the example in the sunflow wiki here:

i have been having some fun getting to grips with sunflow and this library. great work!

Ah, fantastic! Finally a worthy successor to P5Sunflow. A few quirks to get through before you're up and running, at least if you're as crappy a programmer as I am. ;)  But at least less hassle than joons-renderer.

I'm having the same problem with all these libraries, though. Why won't the camera line up in Sunflow as it does in Processing? Am I missing a point somewhere? More tutorials would be much appreciated.

These are images pre- and post render from a very slight variation of the BasicBoxes example, just to illustrate my point. Any clues will be much appreciated.

Keep up the great work!

Hey Ajeger83, on tracing the virtual photons, this is a funny sunflow bug I do not understand either. What you could do is using another rendering engine. There are following:
setAmbientOcclusionEngine(Color bright, Color dark, int samples, float maxDist)
setFakeGIEngine(Vector3 up, Color sky, Color ground)
setInstantGIEngine(int samples, int sets, float c, int bias_samples)
setIrradianceCacheGIEngine(int samples, float tolerance, float minSpacing, float maxSpacing, String globalphotonmap)
setPathTracingGIEngine(int samples)

In case you are using the InstanGIEngine, you can play with the 'samples' and 'sets' values. I always try to go lower and lower. And then sometimes it works.

p1r_dvndr, the camerathing is on the todolist. Right now the processings camera matrix is copied over to sunflow, but it seems to have a different behavior. I will let you know when this is fixed. Thanks for the input.

thanks for clearing up the virtual photons bug, i will try out some different renderers and play with the settings.

I'm getting the glas shader work. First I added some lights which doesn't work, than I draw a white box covering my shape and then the shader works. Then I remove the lights and the it still works. Also change the color of the lights has no effect. So can some please post a example with lights that shows how they work. The example folder of the lib has also lights but removing the point and directional lights seems not to have any effect. 

I just ran into problems getting the latest version to work (OS X 10.6.4, P5 1.2.1). I'm getting the following error message when running BasicScene.pde : 

I was utilizing the BasicScene.pde. 

Is there a way to render > 5000x5000 px stills without heap space problems?

You should be able to when rendering directly into a file.
