we are about to release our x3d player for the iPhone! patrick just finished the OpenGL ES based application today. it is build with the official iPhone SDK and will be available in the AppStore soon.
beta5 of instantplayer will be released today, too. the experimental BrowserTexture is one of my favorite features. XMLHttpRequest was postponed to beta6. meanwhile i found a solution via TCPClient backend for loading and parsing XML.
all news and interesting demos will be presented at WEB3D and SIGGRAPH next week. see you there..
