Re: [FreePV-dev] improved QTVR decoder

[Pablo d'A. <pab...@we...>]

Hi all,

I have improved the pangeaVR based parser quite a bit, so that it should
be able to decode most of the cubic qtvr files out there. (except for those
with compressed headers). If there are some that are not working, please let
me know. I guess not many people must have been using pangeaVR, since it
failed to decode every second pano (or so) on www.panoramas.dk.

done.

I have added three quality levels:

low - nearest neighbour interpolation, fastest option for mesa rendering,
      also see mesa3d.org for more info.
      Should be as fast as possible with mesa, but terrible aliasing
medium - higher quality rendering, linear interpoation.
         Still quite bad aliasing
high - mipmapping - almost no aliasing.

They can be selected from the webpage, or from ~/.freepv config file.
All options that are acceptable in the html page can be used in the config
file. The config file will override any options specified on the command
line or the html page.

Example:
-----------
# Set the rendering quality to low:
quality=low
----------

Btw. is there an easy way to temporarily disable hardware accelerated opengl
under linux?
