Looking at dialog
This dialog is used to input the coordinates of the point towards which the camera was pointing to,
while taking the photograph of the model.
The dialog opens on clicking the Change button of the Looking At section of the
Camera Orientation dialog.
-
Located At
Check this radio button, if you want to manually enter the X, Y and Z
coordinates of the point.
-
Rotate
Check this radio button if you want to rotate the current view direction with respect to the
X or Y axes. Y axis is the default.
-
The rotation axis can be changed by changing the selected value in the drop down.
-
The angle of rotation can be entered in the Deg field.
The rotation angle should be measured in the anticlockwise direction.
-
The Min field can also
be used for fractional values (One degree is equal to 60 minutes).
-
Point to
The default setting for the looking at point is to point to the center of the cube.
We can also change this to make the camera point to the Origin of the coordinate system,
by changing the value of the drop down.
