In this video, you will match SketchUp's coordinate system to the perspective implied in a photograph. This allows you to use the photo to create a 3D model.
- [Instructor] In this video, we're going to match a photo to SketchUp's coordinate system. But before we dive into that, I'd like everyone to get on the same page by using the same template. So if you're on the Mac, go to the SketchUp menu. If you're on Windows, go to the Window menu, and either way, choose preferences. And then click on the template page in the preferences dialog box. And click the first template, simple template, feet and inches. And then close preferences and choose file new.
Now everyone should be on the same page, as it were. Next, go to the camera menu and choose match new photo. Then select Image1.jpg and click open. Now, the match photo window will appear somewhere on the screen. I recommend that you drag it over here, into the corner, so that you can see more of the photo. And while you're in this mode, you can't orbit. If you try to orbit by dragging the mouse wheel, it actually just pans, it allows you to move the photo around on the screen.
Now the first thing to do is set the style. Over here, there are three different styles. This style is good for an interior, because it has an inner corner edge. This one is good for an object that you're modeling. And this is good for an architectural exterior, which is kind of a hybrid of both. Now, we're in an interior scene here, so select this first button, and then we can go ahead and start matching the photo. The way that this works is by dragging these bars. You can drag the bars around and you can also drag their handles.
And as you drag them, some weird things are going to happen to the grid, don't worry about that yet. The way that this works is you drag the top red bar to line up with the top of a surface and the bottom red bar lines up with the bottom of that surface. And then the green bars are meant to line up with a perpendicular surface, so I'm going to drag this over and line this up kind of roughly here at first, and later I'll go in and refine it.
But as I get these bars lined up, the grid is getting closer and closer to the perspective of this photo. Now I'm going to roll the mouse wheel forward to zoom in and I will just refine this by dragging the bars so that they're just a little bit more accurate. Zoom out and then move the mouse over here and then roll the mouse wheel forward to zoom in there and then drag that over too just to refine it.
Now I'm just going to go in and do that to everything because I can improve the perspective. It's important that you get this as accurate as you can because it's going to affect your whole model. So, let's just continue doing this. And finally I think I have to take a look at this one. And that looks perfect, okay.
So those are lined up. The next thing to do is to move the origin point of the grid and you do that by dragging this yellow grip. You can move it around and it's like this person is walking on the floor, although the person looks a little small for the room and we'll deal with that later. But what I want to do later is drag this origin point of the grid to the corner of the room and I'll zoom in there and move that so it lines up just so.
Then I'll zoom out and the next thing I want to do is scale the figure and you do that by dragging up and down on the blue line. So you're not just scaling the figure but you're scaling the space and the figures in that space, so they're going to get bigger or smaller. And I know that the way that this room is is these windows are clerestory windows that are just above eye level. And you can actually see that here with this yellow horizon line. So, what I should do is line up the figure so that their eyes would more or less be on the horizon line.
And then, when you're done, just click done and now SketchUp's coordinate system matches up with the photo's coordinate system.
