Hi,
for the errors above,
I add the below commond:
this->setImplicitBufferAttachmentRenderMask(osg::Camera::IMPLICIT_COLOR_BUFFER_ATTACHMENT);
and changed the LinearDepthSampler`s internal format from GL_FLOAT_RG16F_NV to
GL_LUMINANCE_ALPHA16F_ARB
then no openGL errors appeared, but the program was running very slow(about
2~3fps) and depth test seemed not correct (may be affected by alpha channel)
what I thought is: GL_TEXTURE_2D_MULTISAMPLE is a new token introduced by
OpenGL3.2, and osg may not implement GL3 externsions.
I see a GL3 check item in CMake which is false in default, Is it nessary to
active it and recomplie osg lib to use GL3 externsions in osg?
Thank you!
Cheers,
Kai
