摘要:SampleAppSinbad in action!
這個程式使用SampleBrowser的架構, 不過那個不是重點, 希望之後把它改成一般的OGRE App 架構
它用OpenNI擷取了身形和骨架資料, 然後再套到Sinbad身上, 感覺四肢的動作還不錯, 可以調Smooth參數
要改寫, 先來了解SampleBrowser的流程
OgreBites::SampleBrowser::go
createRoot();
setup();
createWindow();
setupInput();
locateResources();
createDummyScene();
loadResources();
OgreBites::SampleBrowser::runSample
OgreBites::SampleContext::runSample(s);
mWindow->removeAllViewports();
s->_setup(mWindow, mKeyboard, mMouse, mFSLayer); // start new sample
SdkSample::_setup
locateResources();
createSceneManager();
setupView();
loadResources();
CharacterSample::setupContent
mChara = new SinbadCharacterController(mCamera);
setupBody(cam->getSceneManager());
mBodyEnt = sceneMgr->createEntity("SinbadBody", "Sinbad.mesh");
mSword1 = sceneMgr->createEntity("SinbadSword1", "Sword.mesh");
mSword2 = sceneMgr->createEntity("SinbadSword2", "Sword.mesh");
mSwordTrail = (RibbonTrail*)sceneMgr->createMovableObject
setupCamera(cam);
setupAnimations();
mBodyEnt->getSkeleton()->setBlendMode(ANIMBLEND_CUMULATIVE);
setupBone("Humerus.L",q*q2); 設定姿勢
殺掉動作中的key
anim->destroyNodeTrack
rc = initPrimeSensor();
rc = m_Context.InitFromXmlFile(".\\Data\\openni.xml");
rc = m_pSessionManager->Initialize(&m_Context, "Click", "RaiseHand");
mRoot->startRendering(); // start the render loop
FrameRenderingQueued的流程
SampleBrowser::frameRenderingQueued
SampleContext::frameRenderingQueued
mCurrentSample->frameRenderingQueued(evt)
Sample_Character::frameRenderingQueued
mChara->addTime(evt.timeSinceLastFrame);
m_Context.WaitNoneUpdateAll();
m_pSessionManager->Update(&m_Context);
UpdateDepthTexture();
updateBody(deltaTime);
updateAnimations(deltaTime);
PSupdateBody(deltaTime);
pUserSkel.GetSkeletonJointPosition
transformBone("Stomach",XN_SKEL_TORSO, true);
newQ = bone->convertWorldToLocalOrientation(newQ);
bone->setOrientation(newQ*qI);
transformBone("Waist", XN_SKEL_WAIST);
transformBone("Root", XN_SKEL_WAIST);
transformBone("Chest",XN_SKEL_TORSO, true);
transformBone("Humerus.L",XN_SKEL_LEFT_SHOULDER);
transformBone("Humerus.R",XN_SKEL_RIGHT_SHOULDER);
transformBone("Ulna.L",XN_SKEL_LEFT_ELBOW);
transformBone("Ulna.R",XN_SKEL_RIGHT_ELBOW);
transformBone("Thigh.L",XN_SKEL_LEFT_HIP);
transformBone("Thigh.R",XN_SKEL_RIGHT_HIP);
transformBone("Calf.L",XN_SKEL_LEFT_KNEE);
transformBone("Calf.R",XN_SKEL_RIGHT_KNEE);
//do gestures for swards
updateCamera(deltaTime);
return SdkSample::frameRenderingQueued(evt);
結果學到一個技巧
nRetVal = ONIContext.WaitNoneUpdateAll();
可以不用等任何更新就回傳, 所以我之前的OpenRzNI測試程式也可以改成把WaitNoneUpdateAll放在frameRenderingQueued裏
不需要再開一個thread來等資料
