Take Orthophoto
The Take Orthophoto task allows you to create orthographic photos of your SCENE WebShare Cloud projects at high resolutions. Currently, resolutions up to 100 MPx are possible; this value will increase in the future. The rendering process is done entirely in the cloud, which means that you can use any device to create an Orthophoto. You can use any existing SCENE WebShare Cloud project, no additional data from SCENE is necessary.
 
Ground View
Figure 35: Ground View Orthophoto
Ground View orthophotos are aligned to the global XY-plane and are meant for taking photos similar to floor plans or ground plans.
Facade View
Figure 36: Facade View Orthophoto
In Facade View mode, you would for example take orthophotos of walls or house facades: The vertical axis of the image is aligned to the Z-axis of the global coordinate system.
Legend and scale
In its Properties Page both types of orthophoto have a legend and scale on the bottom border. They are added to all images being at least 256 pixel wide.
Colorization
For colorization of the Orthophoto, you can either use real scan point colors or intensity values, or colorize each scan point based on the distance to the Orthophoto image plane.
Depending on your SCENE WebShare Cloud export settings in SCENE, scan point colors and intensity values are available. Colorization by distance is always available. The Orthophoto rendering process will use for each scan:
the distance image at the highest available resolution
the panorama image at the highest available resolution (except for distance-based colorization)
Gap filling
Gap filling improves the image quality by closing small holes in the image plane. Gap filling is active by default, but you can disable it in the Task Panel if you do not need a high-quality orthophoto, or if you are short in time. The task step is optional, you do not have to decide this for every orthophoto.
Gap filling is not configurable in the front-end. The maximum interpolation distance is chosen automatically depending on the image resolution (meter per pixel) during rendering.

Differences to the SCENE Orthophoto App
The SCENE Orthophoto app requires users having the SCENE scan project for taking Orthophotos. In SCENE WebShare Cloud, Orthophotos can be created by any user of the domain.
Since your SCENE WebShare Cloud Orthophoto is rendered on our servers, you can continue working in your SCENE WebShare Cloud project without any limitations or performance impact. In contrast, the SCENE Orthophoto app blocks SCENE while your Orthophoto is rendered.
Orthophoto rendering in SCENE WebShare Cloud does not require any CPU or GPU compute resources of your device. The resolution is not limited by your graphics card memory. The SCENE Orthophoto app uses your graphics card to render the Orthophoto.
The time required for rendering an Orthophoto in SCENE WebShare Cloud can vary depending on the number of users creating an Orthophoto at the same time. The rendering time in the SCENE Orthophoto app only depends on your own computer.
The SCENE Orthophoto app does not offer distance-based colorization.
The export format of the SCENE Orthophoto app is TIFF, the SCENE WebShare Cloud Orthophotos are in PNG format. Both formats are lossless and use transparency where scan points are missing.
The SCENE Orthophoto app exports a single TIFF file including multiple resolutions. SCENE WebShare Cloud exports several images: the full Orthophoto at the desired resolution, plus one image each with a longer side of 2048, 1024, 512, 256, 128 and 64 pixels.
The SCENE Orthophoto app additionally exports a text file with the global corner coordinates of the image. SCENE WebShare Cloud does not yet export such information. Currently, you can only see the global coordinates of the top-left corner of the Orthophoto in the Property Page, shown as Position.
SCENE can use arbitrary oriented clipping boxes to render orthophotos. SCENE WebShare Cloud currently only supports axis aligned (upright or top down).
SCENE uses the project point cloud. SCENE WebShare Cloud uses single scans. This will probably change in the future.
