Node masks are not inherited so if the parent node is off the children will not get traversed...
In Open Flight you could do this by using switches by using Switch Masks to to control with of the children will be visible so in OSG you would not use the node mask but you would want to use is a MultiSwitch and set/getActiveSwitchSet, But having said that if the Nodes are named as below then can you not just traverse each child of aircraft and set teh childrend maks as needed ? you could also resturcutre using a MultiSwitch Best Regards Gordon __________________________________________________________ Gordon Tomlinson Email : gordon.tomlinson @ overwatch.com YIM/AIM: Gordon3dBrit MSN IM : Gordon3dBrit @ 3dSceneGraph.com __________________________________________________________ Telephone (Cell): (+1) 571-265-2612 <-- Note New Number Telephone (Work): (+1) 703-437-7651 "Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival" - Master Tambo Tetsura ----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mark Hurry Sent: Thursday, June 07, 2007 2:18 AM To: [email protected] Subject: [osg-users] Using Node Masks Hi, I have some legacy openflight models that I wish to use in my app. Within the models there are nodes that I need to switch on and off. Fortunately the nodes have a naming convention that allows me to find them. However they are not switch nodes. I have set the node masks something like the following Instance1 -----------------------gear 0x02 \ | \ |----------------------engine_on 0x04 \ | Instance2 ------------Aircraft--------|----------------------engine_off 0x08 / | / |----------------------engine_afterburner 0x16 / | Instance3 | Etc, etc Now my question is, do the lower nodes inherit and then AND the node mask from Instance node? As what I would like to do is switch the various lower nodes on and off by just setting a single node mask at Instance such as 0x06 which would give me gear and engine_on everything else off? Obviously I need a mechanism that has individual masks for each instance as I do not want all instances to necessarliy have gear and engine_on. I have tried coding this but don’t get the results I would expect. I have searched around and not found any examples or hints on how to do this. Am I misunderstanding the use of Node Masks, and/or is there a betterway Thanks in advance for any help/suggestions Cheers Mark [EMAIL PROTECTED] Tel +61 (0)89335 1239 Mob +61 (0)405 095 104 No virus found in this outgoing message.
