USING PHOTOSHOP CS4

3D and technical imaging

Last updated 1/10/2010

The areas selected by Select Paintable Areas, and the paintable areas shown in Paint Mask mode, are partially

determined by the current Paint Falloff setting. A higher paint falloff setting increases the paintable area, a lower

setting decreases the paintable area. See

“Set the paint falloff angle” on page 595.

Create 3D objects from 2D images (Photoshop Extended)

Photoshop can build a variety of basic 3D objects using 2D layers as a starting point. After creating a 3D object, you

can move it in 3D space, change render settings, add lighting, or merge it with other 3D layers.

• Convert a 2D layer (or multiple layers) into a 3D postcard, a plane with 3D properties. If your starting layer is a text

layer, any transparency is retained.

You can add a 3D postcard to an existing 3D scene to create a surface that displays shadows and reflections from

other objects in the scene.

• Wrap a 2D layer around a 3D object, such as a cone, cube, or cylinder.

• Create an extruded 3D mesh from the grayscale information in a 2D image.

• Build a 3D volume from a multi-frame file such as a DICOM medical imaging file. Photoshop combines the

individual slices of the file into a 3D object that you can manipulate in 3D space and view from any angle. You can

apply various 3D volume render effects to optimize the display of various materials in the scan, such as bone or soft

tissue. See

“Create a 3D volume (Photoshop Extended)” on page 605.

Create a 3D postcard

1 Open a 2D image and select the layer you want to convert to a postcard.

2 Choose 3D > New 3D Postcard From Layer.

• The 2D layer is converted to a 3D layer in the Layers panel. The 2D layer content is applied as a material to both

sides of the postcard.

• The original 2D layer appears in the Layers panel as the Diffuse texture map for the 3D postcard object. (See “3D

panel overview (Photoshop Extended)” on page 581.)

• The 3D layer retains the dimensions of the original 2D image.

3 (Optional) To add the 3D postcard as a surface plane to a 3D scene, merge the new 3D layer with an existing 3D

layer containing other 3D objects, then align it as necessary. (See

“Combine 3D objects (Photoshop Extended)” on

page 597.)

4 To retain the new 3D content, export the 3D layer in a 3D file format or save it in PSD format. (See “Export a 3D

layer” on page 603.)

Create 3D shapes

Depending on the object type you choose, the resulting 3D model can contain one or more meshes. The Spherical

Panorama option maps a panoramic image inside a 3D sphere.

1 Open a 2D image and select the layer that you want to convert to a 3D shape.

2 Choose 3D > New Shape From Layer, and select a shape from the menu. Shapes include single-mesh objects like a

donut, sphere, or hat, as well as multiple mesh objects such as a cone, cube, cylinder, soda can, or wine bottle.

Note: You can add your own custom shapes to the shape menu. Shapes are Collada (.dae) 3D model files. To add a

shape, place the Collada model file in the Presets\Meshes folder inside the Photoshop program folder.

• The 2D layer is converted to a 3D layer in the Layers panel.
