Module(s): Animation
You can use the Mount 3D Model in Image tool to insert 3D models in a photograph of the planned site. In order to create these models, you can use the modules in the Architecture family or the tools in the 3D Modeling module. In addition, you can use this tool to determine the eye point and the target point as well as the vanishing points in the scanned photograph. Optical distortion of photographic lenses, the section scanned of the photograph combined with the resolution of the screen restrict the accuracy of this operation. This means that corrections or even a number of attempts may be required.
Before you insert a complex architectural structure, use a simple outline model of the same shape, consisting of 3D objects. Once it fits, you can save it before you replace it with the complex model.
To mount a 3D model in an image
Tip: In the 3D View palette, set the Focal length so that it matches the value used for the photo. For digital photos, you can find this value in the Properties of the file - Details - Focal length of 35mm.
Tip: You can also set the perspective view in a viewport with the Animation view type.
All you need to do is click Match parameters in the 3D View palette. Then click within the viewport with the Animation view type. This is only possible if Navigation Mode is not active
Tip: You can make things easier by creating a hidden line representation of the model: Select the Hidden line image view type at the bottom of the viewport.
The program opens a window with the 3D model. The window's height:width ratio matches the photograph's height:width ratio.
If the bitmap of the photograph is larger than the display resolution, it is fitted into Allplan's workspace.
Note: Then enter the angle included by the two pairs of vanishing lines in plan view.
Tip: Draw the required reference lines in a copy of the bitmap and use this copy to fit in the model. To render the model subsequently, click Surroundings (How) and select the image without vanishing lines.
The photograph will reappear after you have done this.
Note: When the message The horizon is inclined at 1.5 degrees. An inclined horizon cannot be displayed. appears, do the following:
The 3D model is redrawn on top of the photograph.
Now you can save the correct target point and use it for the calculation of the complex model.
Note: Using Surroundings (How), you can select a bitmap for the background later or switch it off.
Note: The perspective view is displayed as a wireframe model. You can use the Render tool to render the perspective view with the photo (bitmap) in the background.
Note: Normally, you do not need a virtual ground plane for rendering an image with a bitmap in the background. So open the Surroundings tool (How) and switch the ground plane off.
