This means, any values such as the look-at vector are not - * *absolute*, they're <b>relative</b> to the coordinate system defined - * by the node which corresponds to the camera. This allows for camera - * animations. For static cameras parameters like the 'look-at' or 'up' vectors - * are usually specified directly in aiCamera, but beware, they could also - * be encoded in the node transformation. The following (pseudo)code sample - * shows how to do it: <br><br> - * @code - * // Get the camera matrix for a camera at a specific time - * // if the node hierarchy for the camera does not contain - * // at least one animated node this is a static computation - * get-camera-matrix (node sceneRoot, camera cam) : matrix - * { - * node cnd = find-node-for-camera(cam) - * matrix cmt = identity() - * - * // as usual - get the absolute camera transformation for this frame - * for each node nd in hierarchy from sceneRoot to cnd - * matrix cur - * if (is-animated(nd)) - * cur = eval-animation(nd) - * else cur = nd->mTransformation; - * cmt = mult-matrices( cmt, cur ) - * end for - * - * // now multiply with the camera's own local transform - * cam = mult-matrices (cam, get-camera-matrix(cmt) ) - * } - * @endcode - * - * @note some file formats (such as 3DS, ASE) export a "target point" - - * the point the camera is looking at (it can even be animated). Assimp - * writes the target point as a subnode of the camera's main node, - * called "<camName>.Target". However this is just additional information - * then the transformation tracks of the camera main node make the - * camera already look in the right direction. - * -*/ -struct aiCamera -{ - /** The name of the camera. - * - * There must be a node in the scenegraph with the same name. - * This node specifies the position of the camera in the scene - * hierarchy and can be animated. - */ - C_STRUCT aiString mName; - - /** Position of the camera relative to the coordinate space - * defined by the corresponding node. - * - * The default value is 0|0|0. - */ - C_STRUCT aiVector3D mPosition; - - - /** 'Up' - vector of the camera coordinate system relative to - * the coordinate space defined by the corresponding node. - * - * The 'right' vector of the camera coordinate system is - * the cross product of the up and lookAt vectors. - * The default value is 0|1|0.
