So all aspects of * this file format are now working, except two issues: * * 1) Jmol's ALT-CTRL center-of-rotation shifting rendering will be approximate. * The issue here is that "perspective" is really a 2D illusion. It's created * by moving points closer to the center of perspective when zooming. * Well, what Jmol does with ALT-CTRL is to apply an XY translation AFTER * setting the perspective, and this rather unusual operation is just not * supported in "real" virtual reality packages. The result is that * whenever the center of rotation in Jmol is not screen center, the * resultant U3D or VRML model view will be slightly different. * * But the good news is that if you don't move the center of rotation from * screen center, the U3D or VRML perspective will be PERFECT - an EXACT * replica of Jmol's perspective (provided you are using set perspectiveMode 11). * * 2) Lighting. Looks like all LIGHT nodes are tied to a parent node and thus * rotate with the model. Perhaps there is a way to indicate that only * one model in a scene is to be rotated, but I haven't found that. * * So the note below is largely just kept for historical purposes. * * Bob Hanson 7/17/2010 * * (a year earlier...) * * I have spent quite a bit of time now tearing my hair out trying to * figure out how to do this right. The documentation is so opaque, * I can hardly believe it. Nowhere is there a definition of what the * view matrix really means, how a view relates to actual camera position * or how translations are to be applied. For example, I simply cannot * figure out how to invoke a default view within a PDF or DeepView short * of having the user go in and choose the view. But then when I get that * going, the zoom is terribly wrong. A "view" has "units" that are * either in pixels or "percent". Here is all we have on that: * 9.5.4.4 U32: View Node Attributes View Node Attributes is a bitfield used to indicate different modes of operation of the view node. View Node Attributes are defined for projection mode and for screen position units mode. * * Period. That's it. What the heck is "screen position units mode"? Beats me. * Nowhere can I find any documentation that actually demonstrates how do * use this resource. * * It's interesting, as well, that the two vwrs -- 3D PDF and DeepView -- * do not give the same result with some of my tests. I can only conclude that * view model is ill defined. * * Amazingly, with VRML it was straightforward to convert from Jmol. We have a * viewing axisAngle that we can pop straight into VRML and get the proper view. * Not so here. I can get initial orientation, but the zoom is all wrong. * * So the U3D documentation reads: * The default node is a group node with no parents. The default node is located at the world origin (the identity transform). There is no default model node, default light node, nor default view node. The default light resource is an ambient light that is enabled, no specularity, and color values rgb(0.75, 0.75, 0.75). A scene graph can have several view nodes that define different viewpoints in the world. Although there is no default view node, there is a preference for having the coordinate system oriented such that the Z-axis is in the up direction with the Y-axis oriented in the direction of the view. The default view resource has the following properties: pass count one, root node is the default node, and fog disabled. * Right, OK. But obviously in a real vwr there IS a default for all of these. * I have instead implemented a default view using animation. This is a total hack. * The true default view in both 3D-PDF and DeepView appears to be the rotation associated * with quaternion (0.6414883, -0.5258319, 0.3542887, 0.43182528) * * The problem that the documentation itself is totally unhelpful. * I had to go through the C++ code for IDTFConverter to find the correct set * of IDTF format fields for the modifiers. Has anyone actually done this?? * * As it turns out, you can get a default view, at least for orientation. * You just add an animation modifier that negates that default quaternion and applies * the correct one. However, ZOOM is a completely different issue. I simply * cannot get the default zoom to work here. * * Bob Hanson 8/15/2009 * * (so the solution to that was to use pdfLatex to set up the zoom) * * */ /* IDTF documentation is in error with regard to motion resources.
