Since the introduction of programmable Graphics Processing Units (GPUs) and procedural shaders, hardware vendors have each developed their own individual real-time shading language standard. None of these shading languages is fully platform independent. Although this real-time programmable shader technology could be developed into 3D application on a single system, this platform dependent limitation keeps the shader technology away from 3D Internet applications. The primary purpose of this dissertation is to design a framework for translating different shader formats to platform independent shaders and embed them into the eXtensible 3D (X3D) scene for 3D web applications. This framework includes a back-end core shader converter, which translates shaders among different shading languages with a middle XML layer. Also included is a shader library containing a basic set of shaders that developers can load and add shaders to. This framework will then be applied to some applications in Biomolecular Visualization.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Image excerpts available on Twitter:</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> Valuable research includes #X3D protein visualization and shader interoperability.</p><p class=MsoNormal> Feng Liu, "Platform Independent Real-Time X3D Shaders and their Applications in Bioinformatics Visualization,"</p><p class=MsoNormal> Ph.D. Dissertation, Georgia State University, 1-12-2007. https://scholarworks.gsu.edu/cs_diss/24</p><p class=MsoNormal> https://twitter.com/Web3DConsortium/status/965277445631836161</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Excellent insight and multiple areas of work might proceed from the accomplishments here.
