Creating Advanced Annotations with SceneVision-3D
You have a completed, edited model you want to enhance or prepare for a presentation. This guide will discuss a
few of the more advanced annotations. SceneVision is running with the scene loaded.
•
Create a Hotspot.
o
Align the photo (see quick guide to color alignment), but only up to step
3:Apply
. Do not do
4:Color
. Do save the scene.
o
Select the photo file in the scene tree. Then select
Make Hotspot from Photo
in the Edit menu. The hotspot will appear in all
aligned data – models, range data, and photos. Double-click on the outline to make the photo appear.
o
Select the arrow button to drag the endpoints of the outline if you would like to make it smaller.
•
Create a High-res Inset.
o
Align the photo (see quick guide to color alignment), but only up to step
3:Apply
. Do not do
4:Color
. Do save the scene.
o
Select
Slice 3D Data
. Select the region of the model which you want to replace with the hi-res photo. It can be all or part of
the photo.
Note: Sometimes it is easy to identify the area in the photo you wish to insert, but difficult to identify the part of the
model. To solve this, use the
Draw Outline
button to outline the area in the photo. Because it is aligned, this outline
will appear in the model. Use that as a guide for the
Slice 3D Data
function above.
o
Select
Insert Hi-res Photo
from the Edit menu. If more than one photo is aligned, choose the photo you wish to use and
select
Okay
. This will insert the full resolution photo onto the selected area of the model. Save the model.
•
Create a person’s Viewpoint, e.g. a point 65in. (or any height) above a particular spot on the floor.
o
Create a plane for the floor by selecting a region of the floor data in the range or model data, and then
Create Plane from
Region
. Name the plane, e.g. Floor or Bedroom Floor.
o
Make the plane large enough to cover the point where the viewpoint will be located, either by dragging an endpoint or
selecting the
Match Plane to Model Bounds
button.
o
Select the plane in the model or in the scene tree. Select the
Draw Perpendicular Line
button.
o
Holding
Ctrl
, click on the spot on the plane where the person was located. A window will open. Enter the height of the
viewpoint, in this case it would be 65. Click
Okay
. A vertical line will appear at that point.
Note: You can drag the point at the base of the line if you want to move it to a different spot.
o
Select the
Create Viewpoint
button. Holding
Ctrl
, select the top point of the perpendicular line. (If data is in the way, turn
off the data by selecting the ‘d’ key, then create the viewpoint, then turn the data back on with ‘d’ again.) The view
‘frustum’ will appear. Rename the viewpoint by right-clicking on it’s name in the scene tree.
o
To lock to the Viewpoint, double-click on it. You can then rotate your view. To set the view frustum to the current
viewpoint direction, right-click on the viewpoint in the scene tree and select
Set Viewpoint Direction
.
o
To return to a standard view, select the ‘
t
’ key or
Move Object
in the View menu.
•
Create a Viewpoint of a photograph, e.g. the camera’s position when the photo was taken.
o
Align the photo (see quick guide to color alignment), but only up to step
3:Apply
. Do not do
4:Color
. Do save the scene.
o
Right-click on the photo in the scene tree and select
Create Viewpoint from Photo
. Rename if desired. See 3. above for
using the Viewpoint.
•
Hyper-Link a file to a point in a scene.
o
Select the
Create Landmark Point
button and, holding
Ctrl
, select the point in the model to hyper-link.
o
When the Annotation Properties window opens, name the point with a
Label
or
Description
. Select its
Show
box.
o
Select
Browse External
to link a file on your computer or network that is not in the scene. Select
Browse Internal
to link a
file that is in the scene. Select the file and select

.
