Position a Model on a Scalable Background Photo

Rendering

A scalable background photo (type Sbackfoto) makes it easier to position the model relative to the background photo, because you can still move and scale the photo relative to the model after the model has been positioned. Add the scalable background photo to the model before positioning the model in the photo. Position the model using the Navigate function. Because the background photo is also visible in the OpenGL shading mode, you can position the model using this mode.

The points determining the position cannot be clicked in a perspective projection. Make sure, that View | Projection | Perspective is not selected before you position the model with the Navigate function.

  1. Select Rendering | Environment | Background. The browser is opened.
  2. Select the folder Misc / Scaled Background Photos in the Vertex Library.
  3. Double-click the thumbnail.
  4. Select View | Projection | Isometric Navigate.
  5. Position the model in the same way as on a normal background photo.

  6. You can control the background photo relative to the model by reselecting View | Projection | Isometric Navigate.
  7. You can refine the model's positioning by moving the mouse a very little at a time.
    • Left mouse button - Rotates the model in the plane.
    • Middle mouse button - Rotates the model around the two points selected first.
    • Right mouse button - Moves the model.
  8. Press the B key.
  9. Control the background photo relative to the model as follows:
    • Move the background photo one pixel at a time with the cursor keys Up, Down, Left and Right.
    • Scale the background photo with the Page Up and Page Down keys.
  10. Finally, accept the position of the model on the background photo by pressing the Esc key.

Note

  • If you want to further move or scale the background photo relative to the model, first select some other projection and then select the Navigate function.
  • If the background photo is not visible in the model window and you have selected Rendering | Render Style | Shaded as the drawing mode, the background photo is not of the Sbackfoto type.
