In-Depth Information
The 3D panel provides various tools for your 3D scene properties, such as
meshes, lights, and materials. The 3D Scene tab includes the scene graph,
which shows you a list of meshes, lights, and materials. It also includes global
settings for the 3D scene. The 3D Mesh tab includes only methods to
navigate and control your model polygons and meshes and adjust the 3D
object shadow opacity.
The anatomy of the 3D Mesh tab is as follows:
1. The top area displays the structure of polygon meshes separated in layers,
which you can display or hide using the Eye icon next to each layer.
2. The preview area displays the selected model. When you select one of
the model meshes from the meshes in the scene graph, notice that
Photoshop draws a bounding box around the targeted mesh.
3. In the left of the preview area, the 3D navigation tools allow you to
control each of the meshes separately without afecting the whole
model. The top home icon resets the properties of the mesh to the
original properties.
4. The right part under the preview area displays information about the 3D
model, such as the number of materials, textures, vertices, and faces.
5. On the left side of the information area are three checkboxes that let you
set the following options:
•
Catch Shadow speciies whether the mesh will display shadows on its
surface that are cast from other meshes.
•
Cast Shadow speciies whether the mesh will cast a shadow onto the
surface of other polygons.
•
Invisible hides the mesh itself and displays only its shadow efects.
6. The bottom icons are global icons in the 3D panel. However, some of
them are disabled in the 3D Mesh tab. The only active icons in this view
of the panel are:
•
Note: Shadows are
dependent on the Ray
Tracer.
Note: These overlays are
dependent on OpenGL
support. You must have
a supported video card
in order to see these
guides.
The Toggle Lights icon, which lets you display or hide the light guides
applied to the object.
•
The Toggle Ground Plan icon, which shows or hides the ground in
the stage.
In the next example, we use the 3D Mesh tab features by loading a 3D object
with multiple 3D meshes, such as the cube in the 3D menu's objects:
1. Create a new Photoshop ile.
2. From the 3D menu, choose New Shape from Layer
>
Pyramid. The current
layer is converted to a 3D pyramid layer (Figure 6.20).
3. Open the 3D panel from Window
>
3D.
4. Click the 3D Mesh icon from the top of the 3D panel; it is the second icon
from the left.
5. Notice that the 3D object includes ive meshes. Select any of the meshes
from the meshes list.
6. Select the 3D Mesh Rotate icon on the left of the mesh shadow
information area.
