[mapserver-users] OpenGL on Linux (Debian/Ubunu)

[Schepers, Benjamin]

Hi list,

has anyone of you made some experience with mapserver and GPU-rendering on Linux (Debian preferred)?

The use case would be to speed up raster-resampling on the fly (nearest <-> average) in WMS and maybe later vector-rendering on complex symbology.
For now raster-rendering in average-mode is three-times slower than resampling with nearest neighbor (which looks worse, indeed).

Are there some pitfalls? Maybe compiling with openGL-driver, other issues, etc.... 

Would GDAL benefit from using GPU on processing very large rasters (aerialimage-BigTIFFs). How would this be done? OpenGL / OpenCL?
Any hints are welcome, I couldn't find that much info on this...

Regards
Ben
