Confirmed, I think that feature could be useful. |

This should be fairly simple to implement, it it something like the following OpenGL calls glPolygonMode(GL_FRONT, GL_FILL); glPolygonMode(GL_BACK, GL_LINE); This means that all front-facing polygons will be filled in and all back-facing polygons are drawn in wireframe. This operation takes effect AFTER backface culling which might need to be disabled with: glDisable(GL_CULL_FACE); Some consideration would need to be given to when and where these calls are used, in order to avoid impacting performance too much with extra state changes. |

I was able to render the patches from behind by disabling the GL_CULL_FACE, although the lines are rendered with a texture. Additionally, the state is changed with every rendered patch, which supposedly isn't performance-wise. I don't know exactly where to start to change it in a good way so I better leave it at that and won't commit this. |

Any chance on a revisit at this point? We've got a lot of new users that won't see their patches (from behind) wondering, "huh?? It is teh broke!" |

OrbWeaver implemented this lately. |
