Hi, I am trying to develop am map application for scientific purposes at my university. Therefor I got access to a lot of tiles (256x256). I can access them and save them to an QImage in a seperate QThread. My Problem is, how can I actually manage to load the QImage into a texture within the seperate QThread (not the GUI main thread)? Or even better give me a Tipp how to approach this problem.
I though about multithreaded OpenGL but I also require OpenGL picking and I did not fall over anything usefull for that.#
Point me to any usefully example code if you feel like, I am thankfull for everything that compiles on Linux :)
Note1: I am using event based rendering, so only if the scene changes it gets redrawn. Note2: OSG is NOT an option, it's far to heavy for that purpose, a leightweight approach is needed. Note3: The Application is entirely written in C++
Thanks for any reply. P.S. be patient, I am not that adavanced as this Topic may (or may not) suggest.
