Hi, When doing GUI elements in OpenGL, it's particularly useful to exactly control the rendering order. Usually, this goes like this: glDepthMask(0); glDisable(GL_DEPTH_TEST); glDisable(GL_LIGHTING); glEnable(GL_BLEND); /* Render GUI back to front */

Re: [osg-users] Controlling the rendering order

Hi Tanguy, The OSG sorts the objects in opaque bin to minimize state changes, this is crucial for performance - it's a pretty fundamental part to efficient rendering and standard practice in high performance graphics toolkts.. This does mean the ordering changes. You have complete control over

: Re: [osg-users] Controlling the rendering order Hi Robert, Do you suggest I create an additional bin type (e.g. GUI_ELEMENT_BIN) in addition to OPAQUE_BIN and TRANSPARENT_BIN, and write my own sort algorithm for those (i.e. render in the same order children appears in) ? Would
