    Re: Offline GLSL compilation

    It's worth remembering that the current binary shaders implementation, together with separate shader objects, greatly reduces the need for fast shader compilation.

    Assuming you are using the two...

    Re: Official feedback on OpenGL 4.0 thread

    In gl.spec, Indexub and Indexubv both have a category of VERSION_1_1_DEPRECATED but neither have a deprecated property as the others with that category do.

    Re: Java to C++ to OpenGL

    If you don't already know it, learn the Java Native Interface.

    After that, you're probably best looking at open source Java bindings to UI frameworks and use them for inspiration. You can get the...

    You might also look at http://research.microsoft.com/en-us/um/people/hoppe/ravg_tr.pdf which covers similar stuff to the Loop/Blinn paper.

    No, he meant the one on the main site. However, the page you linked to also has a Getting Started link which points to the same place.

    That page contains the information you need.

    Your question is a bit like saying "Name me 10 commercial Cobol applications." JVM and CLR based languages are, currently, mainly used for in-house stuff.

    I disagree with your definition of standard.

    DOC, XLS and PPT files are de facto standards as there are independent implementations of them - that is not something that applies to DirectX [1]. The...

    Re: id's "Rage" engine, Tech5 is OpenGL based

    Nobody's said that the driver caching blobs is the worst idea ever, we just don't think it is the best.

    For most invocations of most applications, shaders will have been compiled and their blobs...

    Encrypting shaders in either of the ways you describe won't actually provide much protection to a determined hacker - a simple GL wrapper library will enable getting at the plain text shader in both...
