design_geek_83 Posted February 8, 2011 Share Posted February 8, 2011 I am trying to use the lighting analysis assistant to create a pseudo color range image overlay for a 12-hour period. I have searched around and found tutorials on how to overlay the numeric values onto a rendering for a specific point in time, but nothing about how to overlay multiple pseudo color images. I am working on an urban design project and want to define the areas which will be in sun and which will be in shade throughout a typical day. Does anyone know a way to automate this like you would with a typical sun animation, and what is the best way to overlay the images? Thanks.

alias_marks Posted February 8, 2011 Share Posted February 8, 2011 If spot on accuracy is of most importance. I think you're limited to the hourly data that perez all weather system provides. Maybe they've got more data now, but when I dove into it a couple years ago that's all the info I could find. Link to comment Share on other sites More sharing options...
design_geek_83 Posted February 9, 2011 Author Share Posted February 9, 2011 Thanks, that's exactly what I was looking for! I believe hourly data should be more than sufficient...did you manage to somehow composite the resulting images? Link to comment Share on other sites More sharing options...
alias_marks Posted February 9, 2011 Share Posted February 9, 2011 I did actually comp them together, then just added a timer in after effects that I synced up to some equally spaced (per hour) images. A bit dated, but for what it's worth Link to comment Share on other sites More sharing options...
design_geek_83 Posted February 9, 2011 Author Share Posted February 9, 2011 Nicely done! I was thinking that I would produce a still image that would allow me pick out the areas that recieve the most/least light. It seems like it would be as simple as putting them all into photoshop on different layers and adjusting the opacity based on the number of frames, but I think that would bias the data to the upper most layers. Am I correct to think that? Link to comment Share on other sites More sharing options...
alias_marks Posted February 9, 2011 Share Posted February 9, 2011 er... not exactly sure what your saying there, are you suggesting you might hand paint one of these images? Or break them apart by color? As far as giving each layer equal value. You might play with different blending modes to get a more equal transition... I found opacity to be sufficient enough.

design_geek_83 Posted February 9, 2011 Author Share Posted February 9, 2011 There will definitely be no painting! I will be taking the colors (extreme high and low values) and extract them...that image will then be taken that into cad to influence decisions. I'm sure you're right that opacity will do the trick, I've probably been reading into this whole "layer hierarchy" bit way too much. Thanks for your input.
