LaidlawFX Posted January 5, 2011 Share Posted January 5, 2011 Ok here is some shading documentation I've been working on, on my own time. I'm attempting to doc as much as I can about shading in Houdini as possible. I learn a lot from odforce so I'm giving it back to the community for free. Hopefully I can fix up the sister lighting and rendering document to this soon for those that are wondering. This document is about Hacking the mantra surface shader to learn how your tool works, to better use it. It is what I've been doing to create my UberShader to better understand vops. In essence it's a recompilation of the sesi doc with a lot of odforce wisdom. It will always be a work in progress so keep that in mind. This current version has how the render engine interprets the shader and all the options on the mantra surface shader. I'm trying to add useful images, too... crit most welcome Shading_v003.pdf Quote Link to comment Share on other sites More sharing options...
papicrunch Posted January 18, 2011 Share Posted January 18, 2011 hi, thank you for this great work ! I will print this ! I hope you will find the time to finish the final chapters. papi, Quote Link to comment Share on other sites More sharing options...
LaidlawFX Posted January 18, 2011 Author Share Posted January 18, 2011 hi, thank you for this great work ! I will print this ! I hope you will find the time to finish the final chapters. papi, me to... apparently there is a lot more for me to learn in this area than there was in lighting and rendering, and a lot less sesi stuff to borrow from.

CeeGee Posted January 19, 2011 Share Posted January 19, 2011 Very nice pdf, i hope it become book.. Quote Link to comment Share on other sites More sharing options...
roughsporty Posted January 24, 2011 Share Posted January 24, 2011 you have packaged and described infos very well and I look forward for the next chapters Quote Link to comment Share on other sites More sharing options...
3__ Posted January 25, 2011 Share Posted January 25, 2011 This current version has how the render engine interprets the shader and all the options on the mantra surface shader. I'm trying to add useful images, too... crit most welcome More precise labeling of the images would be nice, EG: parameter_name = parameter_value. It would be great if OGL section could explain exactly how to enable these parameters. Quote Link to comment Share on other sites More sharing options...
zasid Posted January 26, 2011 Share Posted January 26, 2011 HI, Thanks for the great doc,would be great if you put it down to somewhere central like google docs and put some of your info on the front page such as email address and web url so that the next time a new version can be check periodically over your website or in the google docs. As atleat I will be looking forward to the next version of this and finding it in the forum would be a bit hard to combine all the bits and pieces. Thanksalot for this.

Hope you can finish it. Cheers.. Quote Link to comment Share on other sites More sharing options...
LaidlawFX Posted January 30, 2011 Author Share Posted January 30, 2011 cpb - Yeah will do, I spent some time playing with the openGL to get more out of it. I'll explain that more. I hope for the future, they make the openGL nodal like the rest of the parameters can be, then it would be a lot better. zasid - I'll spend some more time thinking about how to do update post to this, for that concept. It's all done in indesign for max future potential and easiest workflow so I don't know how I could tailor that with google docs at the momment. It may be best to update my website with new code other than flash to handle something like that better. It might be best for me to make sure I do one or two more updates some more before I try that, lol, that way I can fade away a little better when I face plant. CeeGee, roughsporty, neonbulbs80 - me too... Quote Link to comment Share on other sites More sharing options...
LaidlawFX Posted February 22, 2011 Author Share Posted February 22, 2011 (edited) So I started updating the OpenGL section of this documentation, and decided to spurn off a new document. Of course it's still needs work, but it encompass all the areas that effect your OpenGL viewport, from shaders, to sops, to your display options. Display options is an area I need to chew through in more depth. OGL_v001.pdf Of the biggest dumb little thing I notices is under the display options, optimization/culling, you can change the clipping planes and set them. Something completely dumb, but it is awesome. Edited February 22, 2011 by LaidlawFX Quote Link to comment Share on other sites More sharing options...

J.Santos Posted March 29, 2011 Share Posted March 29, 2011 Thanks a ton for this! I'm just doing a research for my MA about shaders and VOP's and this will surely be helping me... and will be rightfully credited! Thanks again!!! (now I only need to get paper for the damned printer...) Quote Link to comment Share on other sites More sharing options...
LaidlawFX Posted April 6, 2011 Author Share Posted April 6, 2011 Thanks a ton for this! I'm just doing a research for my MA about shaders and VOP's and this will surely be helping me... and will be rightfully credited! Thanks again!!! (now I only need to get paper for the damned printer...) Glad to hear it is helpful, I'd be interested in seeing your research paper/thesis. I've been poking my head elsewhere in Houdini lately so I haven't gotten a chance to get back to this stuff, but I'm still real interested in any extra info. bytw, Good luck man on your ma, my mfa thesis ended in occlusion, I hope yours gets much farther, lol.
