SpiderGL at Eurographics CG Libs Event

Meet SpiderGL at the Eurographics CG Libs event!
The tutorial will be held by the library developers in June 5th 2013 in Pisa.
Have a look at the event programme and get ready!

The Spider is coming... again!

After a very long time, a new version of the SpiderGL library is ready for preview on GitHub.

The library went under a deep development process that changed the exposed interface (sorry, no backward compatibility), but kept the baseline philosophy almost intact. A comprehensive description of the most important features can be found in a chapter of the OpenGL Insights book dedicated to SpiderGL.
Among the major differences, there are:

  • The WebGL context is hijacked on creation to inject custom SpiderGL extensions: direct state access, fast current object binding query, and wrapper notification
  • All WebGLObject wrappers are automatically kept in synch with their GL state, allowing seamless interoperability with native WebGL usage
  • Fast wrapping of existing native WebGLObjects makes integrating SpiderGL with other libraries easier
  • The new Model class drastically extends the old Mesh concept with a layered structure that can be accessed at different levels, trading flexibility with expressiveness
  • Integrating the Model with a Technique and a ModelRenderer ease the rendering process
  • The documentation is almost complete :)
At this time, there are only a couple of code examples in the git repository, but in the next week more of them will be added. In the next weeks this website will be completely rebuilt, integrating a blog-like section for fast updates and feedbacks.

The spider was not dead, it was capturing its preys.

SpiderGL is a JavaScript 3D Graphics library which relies on WebGL for realtime rendering.

SpiderGL provides typical structures and algorithms for realtime rendering to developers of 3D graphics web application, without forcing them to comply with some specific paradigm (i.e. it is not a scene graph) nor preventing low level access to the underlying WebGL graphics layer.
