Hello,
I am using independent component with vtkOpenGLGPUVolumeRayCastMapper or vtkGPUVolumeRayCastMapper to represent the volume and the labels.
vtk version is 9.1
the first independent component is the labels and its value is :
- 0 if no label , color set to white
- 1 ia a yellow label
- 2 ia a blue label
the second component is the volume
I have problem with the labels colors , if i set the first label opacity to 0 the second label appear fine
if the first label opacity is set to 1 both labels appear yellow as the first one, even if second label opacity set to 0
I noticed that while interacting with volume the color keep changing ,
the first label change between white and yellow
the second one change between yellow , blue and white
