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).


Anybody can help me to solve this problem?

the problem of DepthFunc?BlendFunc?AlphaFunc? how to fix this 


Thank you!
