Subdivision
The Hydra Viewer provides three levels of subdivision (0, 1, 2) for the geometry on display.
Using Subdivision in the Hydra Viewer
| 1. | Select the geometry using the scene graph or viewer. |
| 2. | In the Viewer tab, Open Edit > Set Subdivision Level |
| 3. | Select the subdivision level. |
| 4. | Alternatively use the shortcut keys 0, 1, and 2 to set the subdivision level. |
| 5. | You can also check the active subdivision level by selecting an object and opening the menu. |
Cubes at various levels of subdivision.
Note: This is only applicable to subdmesh types, so polymesh types will need to be converted first.
Anti-Aliasing in the Hydra Viewer
The Hydra Viewer offers four levels of Multi-Sample Antialsing. For more information see Specific Viewer Behavior.
The OpenGL driver for the graphics card returns a value for GL_MAX_SAMPLES. This value indicates the maximum supported number of samples for multi-sampling you can have.
To adjust the MSAA, select Edit > Preferences and click hydraViewer, adjust the antiAliasing setting:
• Full - the full value of the maximum number of supported samples.
• Medium - half the value of the maximum number of supported number of samples.
• Low - quarter of the value of maximum number of samples
• Off - MSAA is disabled.
Note: When you open a new Viewer tab, the number of samples in use for MSAA is reported on the Katana console.
