3D Modeling Overview

• MultiVision takes the oblique images together
  with the DXF layers and uses them to create 3D
  models of objects from the actual images (not
  simulations).
• This important feature can be used for a wide
  variety of applications such as urban planning,
  architectural design, etc.
• MultiVision can sample polygonal, cylindrical and
  conical objects, crop them from the source image
  (exclusive to MultiVision) and create 3D models.

Creating 3D Images
1. In the Toolbar, click
Select for conical objects
Select for polygonal objects

Creating 3D Images from Polygonal Objects
The final point closes the outline and the
complete 3D model outline is displayed.

Viewing the 3D Model
In the Options menu, go to Cropping
Then click View 3D
8
Viewing the 3D Model
The selected object appears in the 3D View window.

Click and drag the mouse to view the object from
all directions

3D modeling component files.

• At the same time, all the images that construct
  the 3D image (all the facades, roofs, etc.) are
  saved separately together with a text file
  containing the XYZ coordinates defining the
  polygons and their locations within the
  rectangular frame.
• 3D modelers can use these to reconstruct 3D
  simulations of the objects.

Saving the Cropped 3D Image
In the Options menu, go to Cropping
Then click Crop
12
Saving the Cropped 3D Image
The Save Croppings As window opens
Give the image a name and save it to the location
of your choice.

Erasing 3D Modeling Outline Elements

• To erase a line in a single window
• In the toolbar, click the Erase button In the
  desired window, click the line in the 3D outline
  you want to erase. That line and all its
  associated elements are erased only in that
  window.
• To erase a selected line from all oblique images
• In one of the windows, click the line you want to
  erase.
• On the mouse, press both buttons. The line is
  erased in all the oblique images (the same line
  in each image)
• To erase all measurement lines
• In the File menu, select Reset Project. All
  measurement and other lines in all images are
  erased.

Duplicating 3D Outlines

• If, after you create the 3D outline and you view
  the image from a different direction but the
  outline does not appear on the new images, you
  can duplicate the outline and drag or copy it to
  the new image.
• Thanks to the known coordinates, no matter where
  you drop the duplicate outline, Multivision
  knows where the outline should go and places it
  on the correct structure.

15
Duplicating a 3D Outline

• With the Polygon or Cone tool, create a 3D
  outline.
• In the Object Transformation menu, select
  Dragorin the Toolbar, click the arrow next to
  the Object Transformation icon then click the
  Drag button .
• Drag the duplicate outline to the same object in
  another window. From the coordinates of the
  original outline, Multivision calculates the
  correct position and drops the outline correctly
  on the object.

Duplicating a 3D Outline (cont.)

• You can also place the duplicate outline anywhere
  in the MultiVision viewer and use it to create
  new outlines for similar objects.
• Once the outline is more or less in the position
  you want, you can use the Shift Duplicate tool to
  position one point of the outline to the
  corresponding point on the new structure and then
  use the Rotate tool to rotate the outline to the
  correct perspective.
