Zebra

Zebra: Surface Analysis

Analyze continuity between surfaces and visually display tangency and curvature conditions between surfaces.

Static Stripes
New in 9

Consumer product 3D models often consist of multiple surfaces that must connect with a specific edge continuity. Zebra ’s new Static mode helps you evaluate these surface transitions by displaying fixed Zebra stripes while the model is rotated.

Static View / Dynamic Stripes
New in 9

With the model held static, rotate the Zebra stripes across your surfaces to closely inspect specific areas of your 3D model. Align the stripes with the surface shape and flow for a clearer view of reflections and surface continuity.

Flexible User Interface
New in 9

Zebra ’s User Interface is Superpowered! Customize your stripes or use the different patterns and colours for completely new ways to analyze a model. The new Radial mode is best suited to analyze transitions on revolved or rotational geometry.

Try It

  1. Download Rhino 9 WIP for Windows or Mac.
  2. Download and open NewZebra.3dm in Rhino.
  3. Run the Zebra command in the prompt . Press Enter.
  4. At the Select objects for zebra stripe analysis prompt , window select all objects in the scene. Press Enter.
  5. In the Zebra dialog:
    1. Select Rainbow under the Mode dropdown menu.
    2. Adjust the Frequency, Rotation, Size and Blur sliders.
    3. Hold down the right-mouse button to rotate the view. Notice that the Rainbow pattern on the model moves as you change viewing angles.
    4. Check Static and rotate the view again. This time, you will see that the Rainbow pattern is stationary.
  6. Check the Show wires option to display the surfaces’ Isocurves while the Rainbow analysis mode is active.
