Well.. Correct me if I'm wrong (/crossfingers hoping i'm wrong) but I'm trying to get VTk running on systems with no video displays, no hardware acceleration, and no running x-server. From what I've experienced in the past (albeit all this testing was back in the
4.4 days), the only way to get that was with Mangled Mesa. Mesa would get visualizations working without hardware acceleration, but still insisted on popping up windows (if you had X running) to do so.<br><br>If I could get my visualizations working (which are all single-frame, render to PNG type stuff) without mangled mesa I'ld be happy. But, in my experience, there's no way to get it working in all three cases in a completely "invisible" (meaning no visible display) way.
<br> 1) Workstation with GPU card & X running, and you're on the display<br> 2) Remote system with no GPU card and X not running<br> 3) Remote system with GPU & X, but you don't own the display (connecting in remotely via ssh)

<div></div>I've been using MangledMesa with VTK (5.0.1) for quite a while now
with pretty good success, but I ran into an issue where I couldn't get
vtkTextActor's to display in the resulting displays at all.<br><br>So I
upgraded to a newer VTK hoping this was fixed (Paraview-2-6 branch) and
recompiled everything. Now my resulting renderings are completely
blank. I did have some issues with getting it to compile as it seems a
few of the files in the Rendering directory have desynced between the vtkMesa*
and vtkOpenGL* versions. I manually resynced them (Just had to copy some
function definitions in the .h files over) and it compiled. <br><br>So my
question is a 2 parter:<br>1) Anyone know how to get TextActors to work with
the 5.0.1 VTK? Was there a known bug around that time that's been fixed,
or is there some new option that must be enabled to get it to work? <br>2) How
to I get MangledMEsa to work in the newer VTK releases? Right now i'm
getting either blank or random-garbage displays.<br clear="all"><br>--
