3D and technical imaging

Last updated 11/30/2015

• 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.)

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

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.

• The original 2D layer appears in the Layers panel as a Diffuse texture map. It may be used on one or more surfaces

of the new 3D object. Other surfaces may be assigned a default diffuse texture map with a default color setting.

See

3D panel overview .

3 (Optional) Use the Spherical Panorama option if you are using a panoramic image as your 2D input. This option

converts a complete 360 x 180 degree spherical panorama to a 3D layer. Once converted to a 3D object, you can paint

areas of the panorama that are typically difficult to reach, such as the poles or areas containing straight lines. For

information on creating a 2D panorama by stitching images together, see

Create 360-degree panoramas.

4 Export the 3D layer in a 3D file format or save in PSD format to retain the new 3D content. See Export 3D layers .

Create a 3D mesh

The New Mesh from Grayscale command converts a grayscale image into a depth map, which translates lightness

values into a surface of varying depth. Lighter values create raised areas in the surface, darker values create lower areas.

Photoshop then applies the depth map to one of four possible geometries to create a 3D model.

1 Open a 2D image and select one or more layers that you want to convert to a 3D mesh.

2 (Optional) Convert the image to grayscale mode. (Choose Image > Mode > Grayscale, or use Image > Adjustments

> Black & White to fine-tune the grayscale conversion.

Note: If you use an RGB image as input when creating a mesh, the green channel is used to generate the depth map.

3 (Optional) Make adjustments to the grayscale image if necessary to limit the range of lightness values.

4 Choose 3D > New Mesh From Grayscale, and then select a mesh option.

Plane Applies depth map data to a planar surface.

Two-Sided Plane Creates two planes reflected along a central axis and applies depth map data to both planes.

Cylinder Applies depth map data outward from the center of a vertical axis.

Sphere Applies depth map data radially outward from a center point.

Photoshop creates a 3D layer containing the new mesh. It also creates Diffuse, Opacity, and Planar Depth Map texture

maps for the 3D object, using the original grayscale or color layer.
