JamesTaylor Posted February 26, 2008 Share Posted February 26, 2008 A collegue of mine has been asked to use Viz in order to compile some Sun analysis renders from which the design / position of Brise Soleil can be obtained. I'm sure i've read somewhere that the max / viz sun system isn't that accurate?? I've had a quick search here but not turned anything up, can anyone confirm the accuracy of the the max / viz sun system, are we talking 80% / 90% / 95% accuracy?? has anyone else produced sun analysis with the sun system to deign brise soleil? were the results good enough?

Koper Posted February 26, 2008 Share Posted February 26, 2008 I won't recommend using the sun system for an accurate scientific/engineering analysis, but for visual feedback it seems to be pretty accurate. You can test it by creating a sundial in your back garden and record the shadow through the day. Then re-create it in 3D and compare. Link to comment Share on other sites More sharing options...
ShaunDon Posted February 26, 2008 Share Posted February 26, 2008 While I can't vouch for the accuracy of the max sun system, I imagine that it would be more than adequate for your purposes. Link to comment Share on other sites More sharing options...
JamesTaylor Posted February 27, 2008 Author Share Posted February 27, 2008 thanks guys, there won't be time to test it as koper suggests - we don't get that much sun at this time of year anyway! - but as no one has come out and slammed the idea i guess it can't too implausable to work this way! The main thing that struck me when i heard the conversation was that feeling that the designers are cutting corners or not doing their job fully and trying to cut out the leg work they'd need to do in calculations etc. i'm still not convinced this is the right way to go about it!... but what can you do!!

Koper Posted February 27, 2008 Share Posted February 27, 2008 the designers are cutting corners or not doing their job fully you do!! exactly, Designers, not engineers. two different profesions. Link to comment Share on other sites More sharing options...
JamesTaylor Posted February 27, 2008 Author Share Posted February 27, 2008 i use designers in the widest sense of the word, and surely an engineer would be classed as sub category of designer... a quick google search for the definition of designer!! designer - someone who creates plans to be used in making something (such as buildings) In the office we have architectural, landscape, engineer and geo engineering departments so when i say the designers i'm sure there is someone or numerous people in the office that should be looking at this and not asking us to do it for them, so to speak.

castroman Posted February 27, 2008 Share Posted February 27, 2008 I saw a related thread over at cgtalk where somebody had tested the sky manager in cinema with really good results. He went out and took a picture and then recreated the settings in the skymanager in cinema, the results was quite good. maybe somebody has tried the same in max?

alfienoakes Posted February 27, 2008 Share Posted February 27, 2008 If you are that worried about it you could always do it the long way..: http://www.learn.londonmet.ac.uk/packages/daymedia/axel/sky/sunpath_calc.html I dont see why it should be in-accurate.. Its a pretty basic thing really; at a given time during the day / year the sun is at a certain altitude / azimuth, and has a certain intensity..? And for Brise Soleil how accurate should it be..! :D Link to comment Share on other sites More sharing options...
