objs Library Method
Short Description: Select objects to create transition
Signature: x.objs (regex)
Class: taccglOBJFile Class
Placeholder for OBJ
<div id="placeholder" style="width:200px; height:200px; float:right; border:1px solid; padding:30px">
The objs method returns an taccgl3DObject Class object
representing a transition displaying one or more 3D objects
stored in the OBJ file.
The result of objs must be passed as second argument to a or actor
in order to attach it to the animation.
regex must be a regular expression. All 3D objects that match the
regular expression are selected. Typically simple regular expressions are "cube" for all
objects whose name contain the character sequence "cube", "^cube$" for the object
named "cube", or "^cube$|^sphere$" for the object named cube and the object named sphere.
Per default the scene is interpreted to be in element coordinates,
i.e. (0,0,0) denotes the top left of the HTML element, (1,0,0) the top right, (0,1,0) the
bottom left and (1,1,0) the bottom right. The initial depth of the HTML is
set identical to the height of the element. Coordintate (0,0,1) of the scene so
refer to the top, left, back point of the HTML element, which is depth pixels behind
the top left of the HTML element.
If the proportions of the HTML element do
not exaclty match the proportions of the scene, the scene is stretched differently for
each axis, so that sphere or a cube appear deformed. Other
ways of adjustment can be selected using modFit.
Examples
var to=taccgl.objFile(); to.read('/objtest/taccgldoc.obj',false); to.mtl.ambientAdjust(0.6); var a=taccgl.actor("placeholder",to.objs("Cone")).modFit(). rotateMiddle(0.7,0,0.7). dur(3).start(); | RUN |
var to=taccgl.objFile(); to.read('/objtest/taccgldoc.obj',false); to.mtl.ambientAdjust(0.4); var a=taccgl.actor("placeholder",to.objs("Sphere|Torus")).modFit(). to(0,1000,0).dur(3).start(); | RUN |
objs works properly only when and if the OBJ file has been succefully downloaded,
i.e. taccglOBJFile.ready returns "ready".
However, if the file was not downloaded because of an error or because of ddmode
then scene makes an empty transition, that does nothing.
So if in ddmode transitions that in dddmode show 3DObjects
should just be left out, nothing special needs to be programmed.
