Use MPxLocatorNode legacy fixed draw code and selection in Viewport 2.0
It is possible to reuse Viewport 1 rendering and picking when using the Viewport 2.0
renderer for plug-in locators. However, this should only be considered a temporary
solution to allow for an incremental migration to Viewport 2.0. The final aim should
be to re-implement rendering using a geometry or subscene override for proper integration.
To reuse the VP1 drawing code implementation when using the Viewport 2.0 renderer,
set the environment variable MAYA_ENABLE_VP2_PLUGIN_LOCATOR_LEGACY_DRAW to any value.
To re-enable the VP1 draw code for selection, set the environment variable MAYA_VP2_USE_VP1_SELECTION
to any value. If this environment variable is not set, then the selection picking
is only performed on the locator's bounding box center.
Requirements and limitations
- You must run Viewport 2.0 in
- mode is not supported, as it does not allow a fixed function pipeline to be run.
- mode is not supported.
- OpenGL state may not be set up in the same way as the Legacy Default Viewport. Legacy
draw code should be careful not to make assumptions about the initial state.
- It is the responsibility of the legacy draw code to set up fixed function state such
as lighting, and so forth.
- It is the responsibility of the legacy draw code to ensure that it does not corrupt
any OpenGL state.
- There is no guarantee of equivalent performance when compared to:
- Legacy viewport drawing
- A geometry/subscene override implementation for Viewport 2.0
- Optimizations from Viewport 2.0 are not supported (for example, consolidation).
- Not all selection options may be supported.
