Photo-match in the xy plane
-
Hello all,
I am trying to do some shade analysis, nothing to fancy or quantitative, I just want to have an idea of where the sun shines (and where it doesn't) over time. I have made a model, put different times in different scenes, exported a 2d .png, overlayed them in the gimp (using multiply) and saved them as one .png.
I would like to take this and put it back into SketchUp and photo-match it, but in the xy plane (the ground) not parallel to the z-axis. Is there any simple way of doing this? I have fiddled around with the adjustments but haven't been able to achieve it...
Is this something that can be done?
Thanks to anyone who has any input

Hi Tpoz, I think that you can do it by changing the perspective guide lines into a one point perspective. Played around with that once before but don't recall what I did, except to move the vanishing points together (I think). You can give that a try if no one can provide better instructions.

by photo match it do you mean just paint the ground with it? cause you can paint the ground with a texture, i don't think you will actually model anything based on the shadows will you?

Hello!
Thanks for both of your advice.
honoluludesktop: I haven't been able to find a straight-forward way of making the photo lay parallel to the ground plane to the model. It may be because I'm unable to move the direction to the blue (z) axis? ...But I'm not sure.
xrok1: I have tried this and it needs a bit of input (like the dimensions of the full-extents of the model) in order to draw a rectangular 'ground' and have the 'material' be the exact same size as the actual model.
Are there any other options? Or easier ways to do these?
Thanks!

At first I thought that if you could make a one point, then you could put the ground on the y or x, z axis, and build the model on its side. Well besides being confusing, unless you don't need them, the real time shadows will be wrong. As for xrok1's suggestion, unless real scale is important, you could turn the model into a component, then scale it to fit the image. Perhaps you can place the model on a face with sides (like a flat box). This way you use the limitations of the limited ground image as a feature of the presentation.

i think you would need to make your ground plane the same proportions as your image ie: 1024x768, which is 4:3 so it could be 100' x 75' for example. then when you create a new material in SU make sure to type these dimensions into the create material hieght width boxes before you select your image. paint the ground plane the you can scale it (make sure you scale uniform) and move it to fit your scene.
