Which 3D engine should I use with QT for the best performance -


i working qt development. using qt 3d engine render 3d view pointer cloud, slow, bad performance. can suggest 1 working qt high performance? orge3d or irrlicht or else. thanks

i don't think integration of 3rd party 3d engine easier fixing code have. if need drawing point clouds think code gpu standpoint - upload points gpu before drawing? draw in 1 batch? animated or static? can simplify shaders and/or blending settings? etc...

if need full blown engine can go written in c++ dmitry said (well, not in c++ that's easier). bear in mind you'll need learn engine-specific api , you'll need many things in specific way. may encounter bugs in chosen engine, you'll need fix or work around. besides of you'll add few mb or more of additional dll's, make project bigger , slower load.

if still want have 3rd party engine integrated here few links start from. few ogre:

i've used qtogre once few years ago, 4.x qt, i'm not sure how work qt5.

if need broader view here's qt page possible integrations: https://wiki.qt.io/using_3d_engines_with_qt

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
