feat(example): PET MIP with window/level adjustment #138

Closed jadh4v closed 2 months ago

jadh4v commented 3 months ago

Add sliders and VolumeRepresentation property values for adjusting the data range applicable for the grayscale colormap. This effectively has the resulting behavior of Window/Level adjustment.

I have verified that, in the fragment shader, the color transfer function is indeed applied after the raw voxel values are projected to the viewport. Therefore, using colorDataRange as a way to apply window/level adjustment for a MIP view is appropriate.

@floryst @jun-sironamedical Please review.

@jadh4v looks good to me, seems pretty straight forward. Might have questions when I try to implement though, but this PR looks good.
