burakdogancay Posted March 12, 2020 Share Posted March 12, 2020 (edited) I wanted to write to you at the camera point. I mentioned that the problem about the camera accuracy has been solved in the subject I opened past days. At this stage, I am working on a simple gimbal camera and when I perform the related camera rotation, the sliding occurs in the related FOV because it provides a dynamic movement according to my intersection on the earth. If you help me ,I would be pleased. My basic algorithm for camera zoom void Sim::Manager::BCameraManager::update_camera_zoom(){ mGimbal.camera->setFov(params.maxFov); float tcurrent_zoom_factor = params.maxFov/params.fov; //these are fov and calculated correctly //float z_far = mGimbal.camera->getZFar(); //float z_near = mGimbal.camera->getZNear(); Unigine::Math::vec3 direction = mGimbal.camera->getWorldDirection(Unigine::Math::AXIS_NZ); Unigine::Math::Vec3 p1 = mGimbal.camera->getWorldPosition(); Unigine::Math::Vec3 p2 = p1 + Unigine::Math::Vec3(direction * 20000.0); auto intersection = Unigine::WorldIntersection::create(); // mGimbal.camera->setViewportMask(0x400); auto res = Unigine::World::get()->getIntersection(p1, p2, 0x00000400, intersection);//4 Landscape // mGimbal.camera->setViewportMask(0x1); Unigine::Math::Vec3 point; if (res) { point = intersection->getPoint(); camzoomparam.distance = length(point - p1); //Here i get intersection between gimbal cam and landscape qDebug()<<"intersection @"; } else { point = p2; qDebug()<<"No intersection!"; } camzoomparam.distance -= camzoomparam.distance/tcurrent_zoom_factor; //Zooming operation for gimbal cam position mGimbal.camCurrentPoint = p1+ Unigine::Math::Vec3(direction * camzoomparam.distance); mGimbal.camera->getCamera()->setPosition(mGimbal.camCurrentPoint);//Here i apply cam position therefore it gives accuracy like a manual zoom operation . //The Only Problem is , intersection point is always change(because landscape point of intersection is changing when i turn gimbal cam to another point) //So I have to keep related cam fov when i move gimbal to right,left and up,down //But i really have no idea } Thank you in advance Edited March 12, 2020 by burakdogancay Link to comment
