Rendering Styles

This section provides information about some of the rendering styles you can apply to objects either through the View toolbar, or through the Customize View Mode dialog box:

• Wireframe

• Shading with Edges

• Colored edges from faces.

Wireframe

This rendering style shows edges and lines only. As far as edges are concerned, when displayed in Wireframe mode, they are applied the color of the mesh and not the one of the "edges + mesh" mode.
However, the color applied to edges depends on the original edge color:

• Edge color is black (default color).
  For each surface or solid, the visualization algorithm retrieves the color of all the object's faces and looks for the dominant color (i.e. the color that is most used). This dominant color will then be used for the display in Wireframe.
  For instance, when you display a blue pad with black edges in Wireframe, edges turn blue:

  Shading with Edges	Wireframe

Now if we take a more complex example: a pad with one red face and the rest of the pad in blue. When setting the pad to Wireframe, the pad's edges are displayed in blue which is the dominant color.

• Edge color is other than black.
  The color applied to edges is not the dominant color of faces but the color defined in the Color list of the Properties dialog box.
  For instance, when you display a blue pad with red edges in Wireframe, edges stay red:

Shading with Edges

This rendering style displays objects in shading mode with all edges, whatever their type (smooth or hidden).

If you modify the object's color, bear in mind that in Shading mode, lineic elements (such as edges or sketches) do not inherit the new color and turn black as shown in the example below:

Shading with Edges. Red color is not applied to lineic elements	Edges and Points. Red color is applied to lineic elements

For detailed information on color inheritance for Assembly objects, see Displaying and Editing Graphic Properties.

Colored edges from faces

This option available in the View Mode Customization dialog box lets you color edges according to the color applied to the object's faces.

Regarding internal edges, if the two adjacent faces have a different color each, the edge is colored according to the color of the face whose bounding sphere's radius is the smallest. The real surface is not taken into account.
The bounding sphere of a face is a virtual sphere-shaped bounding volume surrounding the face and whose center and radius are such that the face is completely within the sphere. Depending on the underlying feature, there are two possibilities:

• The bounding sphere of the face is the smallest sphere that includes the face (most current case)
• The bounding sphere is larger than the smallest surrounding sphere.

Example 1:
Edges between the green and grey faces of the trapezoid turn grey when set to Colored edges from faces because "grey" is the color of the face with the smallest bounding sphere:

Example 2:
The small square in the center turns red when set to Colored edges from faces because the bounding sphere of the red face is smaller than the one of the green face:
