grabbed frames from a standard youtube color video via ffmpeg<br>
used something like $ ./imageSeriesToVolume -sz 1.0 -o test.vtk -i input*.jpeg</div>

loaded test.vtk in paraview 5.0.1 and also paraview 5.4.1<br>
on information tab i see: scalars unsigned char [33,239] <br>

"Map Scalars" on or off I get no RGB colored voxels, of course, because there is only one datum of type unsigned char.<br>

Where are the other two scalars?!? <br>

Looks pretty standard, but no 3 scalar datums for an RGB voxel for non-false-colored volume.<br>
It is perported to work, and all other examples i see are none different from the code i used to generate a .vtk file.<br>

I cannot use IsoVolume If I load the jpegs directly in paraview, but I can get RGB color voxels.<br>
The GOAL is to use IsoVolume on a volume of RGB points from frames from a video sequence.<br>
I have tried on and off for MANY YEARS to figure this out... (its for an art project, metalcasting &3d Printing)</div>
