symek Posted June 29, 2007 Share Posted June 29, 2007 (edited) ok, here it comes. Late early access I'm afraid. All related discussion was performed here, but I think it's right time to jump to a new corner. While waiting for Houdini 9 and Jason's exporter, I've created this one. Still work in progress. For some time I urgently needed to test possibilities of Suflow engine and wasn't too much interested in elegance of particular solutions. Hope you can forgive me. hscript is not my strongest point either (neither python) There is a pdf included in which I try to smooth first interaction with Sunflow for newbies. Python 2.4 (possibly older would work), Java JDK 1.6.0 (or newer), Sunflow 0.07.2, Houdini 8.1. Tested only on WinXP, sorry! Things to be done? I work on particles! cheers, SYmek. PS Please note that this crappy otl wasn't tested carefully and it's very possible it's broken in at least ten points. I have no idea also how it would behave on Linux. Just let me know! PS2 I forgot to mention about it in pdf: Visibility of object and lights in render time is controlled entirely by Display Flags for now. None of Houdini's filtering services works for now. To swich off the light just turn it display flag off. The same with obj. sorry for this incompleteness! See bellow for v0.2 Edited July 2, 2007 by SYmek Quote Link to comment Share on other sites More sharing options...
Andz Posted June 29, 2007 Share Posted June 29, 2007 Thank you SYmek, I'll try to take some time off this weekend to try it out and also Sunflow... I havent used it yet. Now, that fatal question... -"Do you think it will work on the apprentice version?" Quote Link to comment Share on other sites More sharing options...
symek Posted June 29, 2007 Author Share Posted June 29, 2007 (edited) Now, that fatal question... -"Do you think it will work on the apprentice version?" No, I'm pretty sure it won't. Edited June 29, 2007 by SYmek Quote Link to comment Share on other sites More sharing options...
symek Posted June 30, 2007 Author Share Posted June 30, 2007 In Honey v.01 object instancing with loading geo on demand is broken. This is a quick render of fixed Honey. 1000 instances of honeycomb geo (kindly provided by kubabuk) with more then 1 million points each: About 4 minutes to render with low quality sampling. 2 minutes more to load-in, tesselete and build acceleration structure for primitives. 600MB for Java process.

symek Posted July 1, 2007 Author Share Posted July 1, 2007 (edited) Points and lights instancing mixed: EDIT: There are 218 lights in the scene. 1300 teapots (mostly hidden ) with Sunflow Shiny shader. Rendered in... 20 minutes. Edited July 1, 2007 by SYmek Quote Link to comment Share on other sites More sharing options...
symek Posted July 2, 2007 Author Share Posted July 2, 2007 (edited) Just added light instancing and fixed loading geo on demand with instances. cheers, sy. EDIT: sorry guys but v02 was broken in some foolish way. Don't even try to use it. here is a fixed Honey v02 (I hope!) sorry again! sy.

symek Posted July 4, 2007 Author Share Posted July 4, 2007 Nothing like a small example I think. Basic scene with basic features. That doesn't mean you shouldn't read the manual... All setup outside Houdini has to be done. cheers, sy. honey_example_scene.zip Quote Link to comment Share on other sites More sharing options...

Jason Posted July 11, 2007 Share Posted July 11, 2007 Hey SYmek, Now that we're out of the gates with H9, I can share my old (and definitely non-working) SOHO version of the SunFlow exporter I started on a while back. It's very definite that you've far surpassed my little attempt so you might be able to rewrite your entire pipeline in SOHO in just a couple of days - and perhaps my example will give you a kick start. What do you think? Jason Quote Link to comment Share on other sites More sharing options...

What do you think? Jason with a graet pleasure! :batman: PS surpassed? Rather not, I've just got some time to waste that you hadn't I suppose. EDIT: ok, so, SOHO it's a part of Houdini API warped in Python which is designed for easy scene deconstruction for exporting purpose... now I need to find some reference to it (dir(soho) - I suppose knowing SESI ) Edited July 11, 2007 by SYmek Quote Link to comment Share on other sites More sharing options...
crunch Posted July 11, 2007 Share Posted July 11, 2007 ok, so, SOHO it's a part of Houdini API warped in Python which is designed for easy scene deconstruction for exporting purpose... now I need to find some reference to it (dir(soho) - I suppose knowing SESI ) $HH/soho/soho.doc Then, look at $HH/soho/soho.py Then, you might want to look at OGL.py Or, do it in reverse.

Jason Posted July 11, 2007 Share Posted July 11, 2007 with a graet pleasure! :batman: Hey SYmek, Here it is. I think the only part *really worth looking at is figuring out how to translate the polygonal information out using SOHO. Anyway, play away:) sunflow_0.1a.tar.gz Quote Link to comment Share on other sites More sharing options...
