c++ - What buffers to use for stereo in Qt using QOpenGLWidget? -

-

i'm trying stereoscopic visualization in qt. have found tutorials of them use older qglwidget , buffers gl_front_left , gl_front_right.

as i'm using newer qopenglwidget tried drawing images same buffers call gldrawbuffer(gl_front_left) generating gl_invalid_enum.

i saw default buffer gl_color_attachment0 instead of gl_front_left imagine need use different set of buffers enable stereo.

which buffers should use?

you should use

gldrawbuffer(gl_back_right); gldrawbuffer(gl_back_left);

look link

i working on same thing nvidia quadro 4000 . no luck yet, got 2 images offset, ir tansmitter light screen flicker!

got it: sync 60hz, put 120 , works fine still need work on right/left frustrum eureka.
