Only modifications to scene graph objects (not including geometry by-reference or texture by-reference) made from the processStimulus method of a single behavior instance are guaranteed to take effect in the same rendering frame. All modifications to scene graph objects (not including geometry by-reference or texture by-reference) made from the processStimulus methods of the set of behaviors that wake up in response to a WakeupOnElapsedFrames(0) wakeup condition are guaranteed to take effect in the same rendering frame. For modification using user thread or in callback of preRenderer/postRender it is possible that the change not take effect immediately. i.e don't expect a change in preRenderer() will take effect immediately in rendering for the same time frame. It is possible for a frame delay. The solution to workaround is to grap the image a frame later. - Kelvin --------------- Java 3D Team Sun Microsystems Inc. =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
