[Paraview] Questions on vector images output

[Mikhail Artemyev]

Dear all,

I have two questions related to the vector images output from ParaView for
3D. I use ParaView 4.1.0 32-bit on Ubuntu.

1. I've read here (http://www.kitware.com/blog/home/post/508) in the
discussion after the post that if the "colors are generated from point/cell
attributes", "the exporter should be able to handle it once 'Rasterize 3D
geometry' turned off". Otherwise "you may end up with your exported object
appearing grey/colorless". That's exactly what happens in my case. However
my 3D picture is based on a rectangular grid with values of the computed
field defined at the vertices of the grid. I understand that for
visualization ParaView convert the rectangles to triangles first (and it's
clearly seen from the grey/colorless image I have), therefore I'm wondering
if it'll help if I replace rectangular mesh to triangular from my side.

2. The second question is why the labels of the axis have some
triangulation inside them (here is a picture
http://drive.google.com/file/d/0B-0jjlhN_6HyWkR1bWoxc3dVazA/view?usp=sharing).
Is it GL2PS feature? How can I make them look like labels on colour bar?

Thank you,
Mikhail
