If my understanding of the last post is correct, the original image should be (vertically?) "un-cropped" so that the horizon passes through the vertical center of the (resulting un-cropped) photo. All Categories Fonts Illustrations Photos Templates Vectors. I encounter several problems (usually that no matter how I carefully orient the model wrt photos with Photo Match), I always end up with scaling errors in at least one dimension.Ĭould it be related to the last post on the subject? As mentioned in the excerpt of SU Help cited in the last post, no cropping is allowed for Photo Match to work reliably. I therefore built a 3D model of the rooms and try to match it with the available photos. Applying a photo with Match Photo is much easier than drawing that detail and applying materials to individual elements.
The nice thing is that I have an architectural drawing of the building with accurate dimensions. Of course, no idea what was the focal length and/or the parameters of the camera(s) used to take them back then and whether they have been cropped.

I try photomatching archive images (dated 1890 or so) of rather large rooms (workshop) in a building. It helps a lot to 'nearly' match the view of the model before you open the image to be matched.

If you want the latest full desktop app, you’re looking at 300 a year for personal use. At the time of this writing, the only modern free version of SketchUp is a web app. You need to be very careful with adjustments to avoid skewing the vertical off. Use Google SketchUp to teach one and two point pesrspective 16 Keeps. SketchUp has changed hands a few times over the years, once having been owned by Google, and currently owned by a company called Trimble. I've found the same.įor a 2-point image taken with a shift lens (where the shift lens is effectively cropping the image before it hits the sensor) you need to 'un-crop' it - you can assume that if it is true 2-point then the horizon should be in the vertical centre of the image, so extend the crop of the image to align the horizon with the centre and you should be able to get things working. This implies that cropped photos, those taken with a shift lens, or those adjusted in post will not work. Although it may seem possible to use a cropped image, typically vertical lines will not align well across a cropped image and the results will be unsatisfactory." On the left side of your screen, there is a toolbar with some section tools. On this video, Im going to show you how to make a quick presentation drawing for one point perspective, using only Sketchup and Photoshop Click on the link below for Cloud BRUSHES. Navigate to view and select section planes so that it is checked. Once you have your model open, the first step is to make sure your section planes are turned on.
Match Photo currently requires that the point you aimed the camera at is located in the center of the image (also called the center of projection). Watch on Create Sections View > Section Planes.
