basically yes, but you have to apply the inverse of the camera values i was hoping i could skip this computation and use the data that > away3d had calculated as part of view.render() ;) well there is something, but you have to access it after the render call: var objectMatrix:MatrixAway3D = view.cameraVarsStore.viewTransformDictionary[object3d] this will return the transformation matrix that the camera 'sees' of the 3d object. hth Rob On Sun, May 2, 2010 at 1:34 AM, Rich Elmes <[email protected]> wrote: > thanks for the book tip, i'll have a look into that. > > i *think* i understand what i need to do > > the example i gave was overly simplified > > i'm trying to achieve a radar type of thing, i need to know where > other objects are in relation to the player (camera) > > my understanding of it is that i need to translate the object > positions by the camera position and then rotate that scene by the > camera rotation values > > i was hoping i could skip this computation and use the data that > away3d had calculated as part of view.render() ;) > > On Apr 30, 7:50 pm, Michael Iv <[email protected]> wrote: > > Right Choice Man , I have read a few books on 3d math .This one is really > > the best written one . > > > > On Fri, Apr 30, 2010 at 9:47 PM, savagelook < > [email protected]>wrote: > > > > > > > > > > > > > You must have suggested it before, cause thats the one i bought :) > > > > > On Apr 30, 2:28 pm, Michael Iv <[email protected]> wrote: > > > > I can suggest the best book on 3d math ever: > > > > *"3D math Primer for Graphics and Game Development "* > > > > > > On Fri, Apr 30, 2010 at 7:54 PM, savagelook < > > > [email protected]>wrote: > > > > > > > The fact that I can't answer your question with math just got me > out > > > > > of the away3d asdocs and into amazon to purchase a book on 3d > > > > > mathematics. > > > > > > > On Apr 29, 7:37 pm, Rich Elmes <[email protected]> wrote: > > > > > > hi > > > > > > > > is there a way of access the translated positions of objects in > the > > > > > > scene relative to the camera view? > > > > > > > > so say I had an object at 100,100,0 and the camera was at 0,100,0 > and > > > > > > facing along the positive X axis, according to the the camera the > > > > > > object is now directly in front at 0,0,100 > > > > > > > > is it possible to get this information? i couldn't find anything > > > that > > > > > > looked like this in the docs or here in the group. > > > > > > > > regards > > > > > > > > richie > > > > > > -- > > > > Michael Ivanov ,Programmer > > > > Neurotech Solutions Ltd. > > > > Flex|Air |3D|Unity|www.neurotechresearch.com > > > > Tel:054-4962254 > > > > [email protected] > > > > [email protected] > > > > -- > > Michael Ivanov ,Programmer > > Neurotech Solutions Ltd. > > Flex|Air |3D|Unity|www.neurotechresearch.com > > Tel:054-4962254 > > [email protected] > > [email protected] > -- Rob Bateman Flash Development & Consultancy [email protected] www.infiniteturtles.co.uk www.away3d.com
