Sun/Shadow Study - ANNUAL not daily

[Psychoscorpic]

Hi guys.

 

I am trying to animate a Sun/Shadow Study.

 

I want to analyse the sunlight penetration at a certain time of day throughout the year, not from morning to evening.

However, as soon as you try set the keyframes for Days, it automatically selects Hours/Minutes as well, causing the Sun to spin around the "earth" instead of morphing to the same time each day.

 

Anybody know a way to stop this?

(Just occurred to me to Render Nth frames?...)

I looks like you are doing design rather visualization. If that is the case you may want to check Ecotect software at http://www.squ1.com which seems to be the right tool for that task. It has several very useful functions for sun/shadows analisys.

What version of VIZ are you using? I remember that we changed that to allow for the animation of the day to be decoupled from the animation of the time, but I think it was for MAX 6, VIZ 2005 and later.

 

As a workaround, in VIZ 4, you can create an animation using 365 frames. It will then make it so that the time of the day coincides with the frame.

Thanks Hector - DL'd Ecotect - will have a look when I get a chance.

 

Thanks, too, Alex.

Unfortunately VIZ-4, so it's all tied together.

So the 365 frames sort of worked:

Finally discovered that if I set keyframes for the first 8 days, at a specific time of day, and another on day 365, it stops spiralling the sun, and interpolates in a straight line for all 365 days.

Render to MOV with 1 second per frame, et voila.
