Face options

Face options determine how model surfaces appear.

Face Style Draws surfaces using any of these methods:

• Solid Draws without shadows or reflections using the GPU on an OpenGL video card.

• Ray Traced Draws with shadows, reflections, and refractions using the CPU on the computer motherboard.

• Unlit Texture Draws without lighting, instead displaying only the selected Texture option. (Diffuse is selected by

default.)

• Flat Applies the same surface normal for all vertices in a face, creating a faceted look.

• Constant Replaces textures with currently specified color.

To adjust face, edge, or vertex color, click the Color box.

• Bounding Box Displays boxes reflecting the outermost dimensions of each component.

• Normals Displays X, Y, and Z components for surface normals in different RGB colors.

• Depth Map Displays a gray model, using luminosity to reveal depth.

• Paint Mask Displays paintable regions as white, oversampled regions in red, and undersampled regions in blue.

(See

“Identify paintable areas” on page 595.)

Texture When Face Style is set to Unlit Texture, specifies the texture map. (See “3D Materials settings (Photoshop

Extended)” on page 585.)

Render For Final Output For exported video animations, produces smoother shadows and realistic color bleeds from

reflected objects and environments. This option requires more processing time, however.

Reflections, Refractions, Shadows Show or hide these Ray Traced-specific features.

Remove Backfaces Hides surfaces on the back of two-sided components.

Edge options

Edge options determine how wireframe lines appear.

Edge Style Reflects the Constant, Flat, Solid, and Bounding Box options described for Face Style above.

Crease Threshold Adjusts the number of structural lines that appear in the model. A crease or line, is formed when

two polygons in a model come together at a particular angle. If edges meet at an angle below the Crease Threshold

setting (0-180), the line they form is removed. At a setting of 0, the entire wireframe is displayed.

Line Width Specifies width in pixels.

Remove Backfaces Hides edges on the back of two-sided components.

Remove Hidden Lines Removes lines that foreground lines overlap.

Vertex options

Vertex options adjust the appearance of vertices (intersections of polygons that make up the wireframe model).

Vertex Style Reflects the Constant, Flat, Solid, and Bounding Box options described for Face Style above.

Radius Determines the pixel radius of each vertex.

Remove Backfaces Hides vertices on the back of two-sided components.

Remove Hidden Vertices Removes vertices that foreground vertices overlap.
