enum osg::Camera::ImplicitBufferAttachment

Explicit control over implicit allocation of buffers when using FBO. Implicit buffers are automatically substituted when user have not attached such buffer.

Camera may set up two FBOs: primary Render FBO and secondary Resolve FBO for multisample usage. So in practice we have two masks defined for the Camera: implicitBufferAttachmentRenderMask implicitBufferAttachmentResolveMask They can be set together by setImplicitBufferAttachmentMask method, or separately by setImplicitBufferAttachmentRenderMask and setImplicitBufferAttachmentResolveMask.

Camera defaults are USE_DISPLAY_SETTINGS_MASK which means that by default Camera chooses to substitute buffer attachments as defined by DisplaySettings.

Usually DisplaySettings implicit buffer attachment selection defaults to: DEPTH and COLOR for both primary (Render) FBO and seconday Multisample (Resolve) FBO ie: IMPLICIT_DEPTH_BUFFER_ATTACHMENT | IMPLICIT_COLOR_BUFFER_ATTACHMENT

If these masks are not changed and user did not attach depth buffer and/or color buffer to Camera, then OSG implicitly substitutes these buffers. By default it does not implicitly allocate a stencil buffer. Use implicit buffer attachment masks to override default behavior: to turn off DEPTH or COLOR buffer substitution or to enforce STENCIL buffer substitution.

Note that both values are ignored if not using FBO. Note that the second mask value is ignored if not using MSFBO.
