Modernizr checks for the <i>WebGLRenderingContext</i> framework, which renders WebGL. This is opposed to the ChemDoodle Web Components, which check for WebGL support by attempting to render a WebGL scene. So what does this mean? Either, the Mobile Safari developers mistakenly forgot to remove part of this framework, or there are currently plans to provide this support.<br /><br />WebGL is an HTML5 technology, and since Apple is one of the largest supporters and founders of HTML5, I do believe we will see WebGL in Mobile Safari. The anticipation will be difficult, but it will also make WebGL on iPads so much more enjoyable :).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6701417360427959244.post-11981566950272130022011-03-09T10:55:51.371+01:002011-03-09T10:55:51.371+01:00Yes, as far as I know WebGL is not even turned on ...Yes, as far as I know WebGL is not even turned on by default yet in the nightly builds of Webkit.

Apple has a habit of hiding feature details until the day they are released. I believe we should see WebGL on iPhones and iPads within 6 months of WebGL support in Safari.<br /><br />I would also like to mention that our team is developing great new WebGL features. We will provide several new styles and rendering improvements. The next update should be in about 2 weeks.<br /><br />@Egon - The ChemDoodle Web Components library is a scripting framework. Unlike JMol, which is an application, and requires scripts to be manipulated, ChemDoodle Web Components are themselves a script and can be manipulated at runtime with basic Javascript. You can do anything and everything to any component and the data it renders at anytime. I recommend you complete the tutorial here: http://web.chemdoodle.com/tutorial<br /><br />Also, we are not trying to compete with JMol, since as you said, it is an old technology. We are providing an open-source (GPL) HTML5 chemical graphics and cheminformatics solution for web browsers and mobile devices. As with all software projects, it will grow over time. JMol's feature set is a good first goal for functionality. After we match it, we will match functions from more complex 3D rendering tools.<br /><br />If you want to follow our progress, please subscribe to the RSS feed at iChemLabs: http://www.ichemlabs.com/feed/rss2/Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6701417360427959244.post-91534951736845594532011-02-16T09:54:15.344+01:002011-02-16T09:54:15.344+01:00JMol is an older project, competing with Jmol (htt...JMol is an older project, competing with Jmol (http://www.jmol.org/), with limited functionality :)<br /><br />Anyways... one of the powers of Jmol is the scripting.
