Hi, everyone~ I implemented GPU based MarchingCube algorithm in OSG 3D engine. But i have got something strange, here is the picture.
[Image: http://i56.tinypic.com/wvcv87.jpg ] some dark gray levels disappear... I just put the generated osg::Geometry object into transparent with function and give an alpha value in fragment shader(constant, e.g. 0.5). sset->setmode(GL_BLEND)... Anybody can help me to solve this problem? the problem of DepthFunc?BlendFunc?AlphaFunc? how to fix this ... Thank you!
