15.4.3. Insert 3D model into perspective

With this command you can insert the object into the perspective of the photograph in a way that you assign a point of the perspective plane to the corresponding point of the 3D model (see the previous figure).

The program fits the 3D model into the original viewpoint of the photograph. If you apply precise values the program performs the command with high accuracy.

• Define a point on the perspective photograph: point 1.

• Define the appropriate 3D plane on the object: point 2, or
  choose from the options of SSOLID MENU.

ENTERThe selected plane is rotated in the appropriate direction.
NOSelects another plane.

• Specify the corresponding reference point on the 3D plane: point 3, or select an option from 3D point definition POPMENU.

As a result the program projects the 3D model into the photograph.

This way we have inserted the model into the photograph and now it is displayed in the same perspective as its surroundings.

2If the perspective has not been defined precisely, the result can be imprecise. In this case modify the definition of the perspective by applying the Modify definition command.

There are two more tasks to be completed:

• to create the photorealistic display of the model, and

• to edit the ready image in a way that the sides of the building does not hide the parts of the photograph.

If you are satisfied with the result of the previous perspective transformation, select Insert 3D model into perspective in Render window command.
