# Qt Canvas 3D Logging

Qt Canvas 3D makes use of Qt's categorized logging. The following categories are supported:

Category | Description
--- | ---
`qt.canvas3d.info.debug` | Logs on high level information about the OpenGL driver.
`qt.canvas3d.rendering.debug` | Logs all the method calls in Qt Canvas 3D.
`qt.canvas3d.rendering.warning` | Logs all warnings on from Qt Canvas 3D internal verifications that happen before a OpenGL method call is made to the actual graphics driver.
`qt.canvas3d.glerrors.debug` | Logs all the OpenGL driver level errors. This entails calling `glGetError()` after each OpenGL driver call and this will cause a negative performance hit. Please use only when necessary to find root causes of rendering errors.
