Displays highlights from a light source (single or multiple light beams). Useful for identifying where the reflected light does not move smoothly.
Iso Angle highlighting helps you find surface flaws. A common use for Iso Angle is to identify adjacent surfaces with mismatched tangents—in other words, surfaces that do not meet smoothly. You can also use Surface Continuity for this purpose, but Iso Angle gives you a clearer view of the surfaces.
Through a light source manipulator, this mode lets you sweep beams across a surface. You can see where the reflected light does not move smoothly. A jump in the reflection indicates flaws in either the surface or its boundary with a second surface.
Single, double, multiple (red, black, and white, or rainbow) can be used.
Iso Angle highlight options
This mode shows iso-angle lines on surfaces to help you visually evaluate continuity across surface boundaries.
- Map Type
-
Controls how the iso-angles lines display.
Single – Displays a single black and white iso-angle line.
Double – Displays a wide iso-angle line.
Multiple – Displays red, black, and white iso-angle lines.
Rainbow – Displays bands corresponding with each color of the rainbow.
- Width
-
The width of white band iso-angle lines. This option is only available if Type of Bands is Single.
- Number of Bands
-
The number of times colored band iso-angle lines are repeated on each surface. This option is only available if Type of Bands is Multiple.
- Blur
-
The blurriness of iso-angle line edges.
- Transparency
-
The transparency of surfaces with iso-angle lines.
- Vector Control
-
The position of the vector represented by the arrow icon (light source).
- X, Y, Z
-
Aligns the light source vector with the X, Y or Z axes.
- Update From Selection
-
Set the direction of the light source to be that of an already selected vector or plane. In the case of a plane, the direction perpendicular to the plane is used.
- Show Manip
-
Displays the diagnostic shader manipulator, which you can use to
- Curve Control
-
Controls whether Visual curves-on-surface are created from iso-angle lines, or actual CoS curves-on-surface. The latter can be used for modeling operations such as geometry creation, trimming, or measuring.
Note: If Construction History Updates During Transforms is turned on (in Preferences > Performance Options), curves-on-surface temporarily become visual curves during the interactive updates to provide faster redraw. This does not happen if the curves-on-surface have locators on them, are used in trimming, or if the transformation requires the tessellation to be recomputed (for example, in Transform CV). - Show Curves Only
-
Disable the shading and show the iso-angle lines as curves only.
- Create
-
Create iso-angle curves.
- Delete
-
Delete iso-angle curves.
