Hi Tristan, The error that the OSG is emitting couldn't be more direct - the extension required to support ALPHA_MAX isn't support by your OpenGL driver.
Do a glxinfo to see what is supported. If what you want to do isn't support then you'll need to go off and find another route to doing what you want to do. Robert. On 3/16/07, Tristan McMillan <[EMAIL PROTECTED]> wrote:
Hi OSG Community I am trying to use osgblendequation example. However for ALHPH_MAX/MIN I get the following errors: "Equation name = osg::BlendEquation::ALPHA_MAX Warning: BlendEquation::apply(..) failed, SGIX_blend_alpha_minmax extension is not supported by OpenGL driver. Equation name = osg::BlendEquation::ALPHA_MIN Warning: BlendEquation::apply(..) failed, SGIX_blend_alpha_minmax extension is not supported by OpenGL driver." Does anyone know how to solve this? I have loaded the latest Nvidia driver for Fedora core 4 but that has still not helped. And I haven't found anything like this in the forums yet.
