--------- i want to export the camera target... with cinema 7 it works fine, with 8 i get a NIL object ?! here the snippet: // CAM TARGET var objTag = pObject->GetFirstTag(); while(objTag != NULL) { var objClass = getclass(objTag); if (objClass == TargetExpressionTag) { // TARGET NAME var targetContainer = objTag->GetContainer(); var strTargetName = targetContainer->GetData(TARGETEXPRESSIONTAG_NAME); println("camtargetame: ", strTargetName); WriteChunk(CHUNK_CAMERA_TARGET_NAME); WriteZeroString(strTargetName); var tmpObject = g_pDoc->GetFirstObject(); while(tmpObject != NULL) { var strTmpName = tmpObject->GetName(); if ( 0 == strcmp(strTargetName, strTmpName) ) { // TARGET POSITION var vecTargetPos = tmpObject->GetPosition(); println("camtargetpos: ", vecTargetPos); WriteChunk(CHUNK_CAMERA_TARGET_POSITION); g_pFile->WriteReal(vecTargetPos.x); g_pFile->WriteReal(vecTargetPos.y); g_pFile->WriteReal(vecTargetPos.z); } tmpObject = tmpObject->GetNext(); } } objTag = objTag->GetNext(); }

Hi, in R8 the target object is not a string anymore but a BaseLink. And baselinks are unfortunately not accessible anymore in R8 via COFFEE. Either you switch to C++ or you will need to wait for an updated COFFEE SDK (or somebody writes a plugin that allows to pass the baselink to COFFEE - I even remember somebody actually is working on such a plugin). There is no workaround for this afaik. Best Samir

how lame... and how to get the "up" vector from the camera ? rotations ?

what do you mean by "up" vector? The rotations of the camera can be accessed just as any other object rotations with GetRotation or u use the local/global matrix of the object for the rotation values. See the COFFEE docs for more information. (And maybe a good book about OOP Best Samir

i am coding an exporter for my d3d9 engine... and there, the camera has an "eye" (cam-pos), "lookat" (cam-targetpos) and "up" (?) vector... opengl also has those 3 vectors... so my question is how to get that "up" vector out of cinema. www.igoronimo.org/work.html some screenshots...

Get the matrix of the camera object. It sounds like:
var mat = cam->GetMg(); eye = mat->GetV0(); lookat = mat->GetV3(); // Z axis up = mat->GetV2(); // Y axis
I assume that D3D doesn't store the X axis vector since it's always Y x Z.
