Hi Mairan,
Good to hear this is working so far. There are options to set scale
and window size in XObjView, and an XObjView_Rotate to spin it. Bonus:
XObjView_Write_Image to save a snapshot to a file.
There's not a simple way to get different axis scaling as you had in
your original triple-plot, but for this, I feel that keeping them the
same (isotropic) in all views is preferable for communicating the true
3-D shape.
I believe I have set up exactly the views you want (YvsX, YvsZ, XvsZ),
but I'm not sure if your original views in the PDF were rendering
exactly right. (if the second plot were correct, I'd expect in the
first plot that the middle overlap section would show the red lump in
front, not the blue)
I hope this helps!

QHull, xyz2, tri2

conn1 = [Replicate(3, 1, (N_Elements(tri1)/3)), tri1]

oMesh1 = Obj_New('IDLgrPolygon', xyz1, Polygons=conn1, Style=2,
Color=[255,0,0])
; You probably want to use Vert_Colors to add the colour
information!
oMesh2 = Obj_New('IDLgrPolygon', xyz2, Polygons=conn2, Style=2,
Color=[0,0,255])
XObjView, [oMesh1, oMesh2], $
XSize=200, YSize=300, Scale=(1/Sqrt(3)), $ ; Default scale is 1/
Sqrt(3)

XObjView_Write_Image, 'snapYvsX.png', 'png'
Wait, 1

XObjView_Write_Image, 'snapYvsZ.png', 'png'
