Re: Recent experiment [Damn, I feel like I've answered this request a half-dozen times -- because I have, but every time something (power outage, connection drop, BSOD, brain freeze) has kept me from hitting the final 'post reply' button. Fingers crossed for better luck this time....] What I planned to do was create a cylindrical object or curved wall large enough to encompass the entire modeled home and map against it the entire 200° panoramic view I shot from the roof. But that seemed like a lot of work and a lot of trial-and-error to get the scale and position accurate, so when I was preparing to render a test run of this image from this reply, I decided to fake it. To create that background image, I used two 6-color boxes scaled to 51' x 20' x 1/8", each with a single component image from the panorama mapped to it. (As I recall, I ended up having to go with the 6-color box because textures wouldn't map correctly against the single-colored box models in the library. FWIW, the photo texture replaces the red face.) Proper position and elevation were determined by watching the 3d view while wiggling the image object around manually. To visually match some photos I'd taken from the property, the panels ended up roughly 30' off the end of the house and about -5' in elevation.) The back yard of the property is dominated by an enormous, oddly pruned Mediterranean cypress. To approximate its appearance, I started with a snapshot of its trunk and branches and created from it a transparent background PNG. I then mapped that image against a transparent box, scaled it to a similar size, and placed it between the cityscape images and the house. The following screen shot highlights the three flattened boxes used to create the background. The main problem with this approach is that the 'billboards' have to be manually tweaked before each scene. For instance, the render that opens this thread uses the same three image components as the one from the earlier thread -- but they had to be raised from 7' to 10' each, rescaled, and the race of some models altered. |
