Quaternion rotation in 3D

viniltc

Hi all,

I've got a IMU sensor. I get quaternion values from the sensor. I'm looking forward to a program to visualize the 3D rotation of the sensor. Any suggestion would be helpful.

Thanks in advance

@viniltc said in Quaternion rotation in 3D:

visualize the 3D rotation of the sensor

In which way? Just visualize the rotation angles or rotate an actual 3D object in a virtual environment?

You can use Qt3D (C++ or QML) for that.

You can use just a standard cube (other basic shapes are supported) or you could create your own mesh / .obj - file with e.g. Blender and import it.

Qt3D https://doc.qt.io/qt-5/qt3d-index.html

Here are some examples https://doc.qt.io/qt-5/qt3d-examples.html.
I can recommend the ShadowMap QML Example (QML) and the Basic Shape C++ Example

You can set the transformation by using QQuaternion and your quaternion data directly
