Rendering Differs based on the default orientation for MPR

[Alaeddine]

Describe Your Question

• Hi, So in VolumeViewport3D, when i change the initial default orientation axis to CORONAL, or even use setCamera the 3D rendering appears to be brighter and stays the same even when rotating with a trackball. This difference in rendering appears even in the example for orientationMarker in the github code.

What steps can we follow to reproduce the bug?

1. Open the github repository
2. yarn install
3. yarn run example OrientationMarker
4. Observe teh difference between the two Volume 3D viewports

 this._csViewport.setCamera({
      viewPlaneNormal: [1, 0, 0],
      viewUp: [0, 0, 1],
    });

My question is , how do i keep the rendering consistant even when changing orientations ?
