Site Insertion Tool

In the Perspectives inspector, Insertion enables to position a camera precisely vis-a-vis a model or photo. Position a background image before using this command.

After aligning the X, Y & Z axes in the 2D View and in the Preview window, the model is positioned easily in the background image.

Example

The model is displayed

The background picture is positioned

NB: Please do not use a set of pictures as the vanishing points will be not combined.

Insertion Command

The insertion dialog allows you to define the reference axes and to adjust the axis in 2D and in Preview windows, to display the model and run/stop the calculation.

Open the “Insertion” tool in the Perspectives Inspector.

How Do You Do This?

When the palette is opened in Preview, the background picture and a trihedron are displayed with vanishing lines and a magnifier.

NB: The 3D model is hidden and is only visible when the Show 3D Model box is checked. Leave it unchecked to see the background picture while positioning the axis.

Matching the Position of the Trihedron in 2D View and in Preview

In 2D View

Display the plane view, then set the origin using the yellow dot (the intersection of the red X axis and the green Y axis) on the geometry. Display the elevation view and set the origin (the intersection of the red X axis and the green Y axis depending on the elevation and the blue solid line of the Z axis) on the geometry.

In the above example, we set the trihedron origin in the lower left-hand corner of the garage. The base of the new garage will match the position of the old one seen on the picture.

In Preview

On the background, set the origin of the trihedron, placing the yellow dot on the chosen axis in the background.

Position the Two Pairs of Dashed Lines

One pair corresponds to the red X axis and one pair is green and corresponds to the green Y axis.

NB: The red X axis, green Y axis and blue Z axis lines must never collide.

In our example, we start with the two green dashed lines: align one with the horizontal gutter of the roof 1 and then  align the other with the base of the motorbike window 2.

Then set the two red dashed lines:

align one with the base of the sidewalk 1 and then align the other with the horizontal gutter of the house on the left-hand side 2.

In Preview, the magnifying glass helps you place the axis precisely on the background image. To activate the magnifying glass, turn the mouse wheel. Each incrementation increases the zoom from x2 up to a maximum of x8.

Nota 1: No need to set the green or red lines on a same plane, only be sure to respect the vanishing lines. 

NB 2: In Preview, the red, green and blue axes cannot be dragged, only the dashed lines and the origin of the orthonormal axis can be moved.

Define the Scaling Axis

In the Insertion palette choose one of the axes (X, Y or Z) which defines the scale. It refers to the scale between the model in 2D View and the background picture. In 2D View and Preview ,drag the yellow handle along the solid line.

Show the 3D Model

In the Insertion palette, check the box Show 3D Model.

Automatic Camera Calculation

Click on Start: Artlantis calculates in real time the position of the camera. When you are satisfied, click on Stop and then OK. This will close the Insertion palette and automatically lock the coordinates of the camera.

NB: While calculating, any insertion parameter can still be manipulated: the origin, the dashed lines or the position of the yellow handle.
