\class nvvk::Axis
|
|
|
|
nvvk::Axis displays an Axis representing the orientation of the camera in the bottom left corner of the window.
|
|
- Initialize the Axis using `init()`
|
|
- Add `display()` in a inline rendering pass, one of the lass command
|
|
|
|
Example:
|
|
\code{.cpp}
|
|
m_axis.display(cmdBuf, CameraManip.getMatrix(), windowSize);
|
|
\endcode
