I am successfully able to render a 3D dataset using vtkVolumeRayCastMIPFunction and vtkVolumeRayCastMapper.<div>Now, for certain sparse set of 3D coordinates within this dataset, I want to overlay specific RGB color values for them in the above Max Intensity Projection.</div>
<div><br></div><div>Which would be the best VTK classes to do this?</div><div>Ideally, I would like to feed in the RGB values somewhat like this:</div><div><br></div><div>//pseudocode over an iterative loop</div><div>appropriateVtkCxx(x, y, z, R, G, B);</div>
<div><br></div><div>suggestions would be much appreciated!</div><div><br></div><div>best regards,</div><div>Divya</div>
