osg Sequence
Hi,
Im loading an ive file with an osg sequence that i would like to control. Whats the best way of doing this? I would like to be able to stop, start and set the current time of the sequence. Thanks TarkaDahl |

There's currently no built-in support for this, but we will add it to a future release.
If you are familiar with C++ programming and OpenSceneGraph, you could write a Vizard extension that does this. Our SDK is freely available and contains an example for writing an extension that interacts with the underlying scene graph of a node. |

Hi
Im having a problem with this ive been looking at the example of creating an modifier using the sdk but how do a get from the osg::Node to the osg::sequence ive looked at the documentation here. http://www.openscenegraph.org/docume...cs/a00654.html and it explains functions that i need to call on the osg sequence but i cant find how to get to the osg::sequence Sorry it that doesnt make sence. but ive not used c++ for a while and have only done the basics of OpenSceneGraph. I will do more reading about it later but any help would be good. Thanks TarkaDahl |

Support for controlling osg::Sequence nodes is in the latest version of Vizard (4.02). Here is some sample code:
Code:
import viz viz.go() model = viz.add('sequence.ive',pos=(0,1.5,4)) osg = viz.add('SceneGraphTools.dle') sequence = osg.Sequence(model) import vizact vizact.onkeydown(' ',sequence.setMode,vizact.choice([sequence.PAUSE,sequence.RESUME])) vizact.onkeydown('r',sequence.setMode,sequence.START) vizact.onkeydown('1',sequence.setFrame,50) Code:
class Sequence(object) | Methods defined here: | | __init__(self, node, name='') | | getBegin(self) | Get the begin frame | | getClearOnStop(self) | Get whether to show no children after stopping | | getEnd(self) | Get the end frame | | getFrame(self) | Get the current frame | | getFrameCount(self) | Get the number fo frames | | getFrameTime(self, frame) | Get the time for the specified frame | | getLoopMode(self) | Get the sequence loop mode | | getMode(self) | Get the sequence mode | | getNumRepeats(self) | Get the number of repeat times | | getSpeed(self) | Get the sequence speed | | getSync(self) | Get whether to sync frames with frame time | | iterFrameTimes(self) | Returns iterator that yields frame time values | | setBegin(self, begin) | Set the begin frame | | setClearOnStop(self, clearOnStop) | Set whether to show no children after stopping | | setEnd(self, end) | Set the end frame | | setFrame(self, frame) | Set the current frame | | setLoopMode(self, mode) | Set the sequence loop mode | | setMode(self, mode) | Set the sequence mode | | setNumRepeats(self, repeats) | Set the number of times to repeat | | setSpeed(self, speed) | Set the sequence speed | | setSync(self, sync) | Set whether to sync frames with frame time |
