<div>Hi experts, </div>
<div> </div>
<div>I have a polydata which contains a set of points and their data attributes (Scalars) of type vtkIntArray.</div>
<div>I use the filter Delaunay3D in order to tetrahedralize this data. In this way, I can do volume rendering by using vtkUnstructuredGridRayCastVolumeMapper.</div>
<div> </div>
<div>However , when I got this :</div>
<div>ERROR : Can't use the ray cast mapper without scalars!</div>
<div> </div>
<div>Is there anyone who has an idea/issue of this matter ?</div>
<div> </div>
<div>Thank you in advance.</div>
<div> </div>
<div>Best regerads!</div>
