This exercise demonstrates how to use a custom script with Geographic Imager to open a DEM, overlay it with an image and to create a 3D effect. See Automating Geographic Imager for more details.
1.In Adobe Photoshop, click File > Scripts > Browse. Browse to the \Tutorial Data\Sample Scripts folder, click 3D Overlay Script.jsx, then click Load.
No images are open, so you are prompted to open a DEM. This script also works if a DEM is already open.
3.Browse to the Mt Olympus 3D Landscape Data folder, select MtOlympus.dem, then click OK.
4.This script allows you to choose a image to overlay the DEM. If no image is chosen, Terrain Shader can be used to create a color map for it. You’ll choose the accompanying Mt. Olympus GeoTIFF image to overlay.
6.Browse to the Mt Olympus 3D Landscape Data folder, select MtOlympus.tif, then click OK.
A 3D operation is performed to the Rocky Mountains DEM and the Rocky Mountains GeoTIFF is overlaid on top of it. This image is still considered a dynamic object in Adobe Photoshop and it can be controlled with the 3D panel (Window > 3D) and the Object Rotate Tool and Camera Rotate Tool in the Tools toolbar.
The 3D panel has options to change lighting settings (such as opacity, light source, intensity) and render settings (such as 3D options, cross section, quality). The vertical exaggeration can be adjusted with the Object Rotate Tool and the green axis adjustment.
When creating a 3D representation, georeferencing is not maintained.
