tween.js - Tween camera position while rotation with slerp -- THREE.js -


I want to add the camera position during rotation.

This is my function: 

  Function steps andlookup (camera, DSTOPO, DSSILAT, options) {options || (Option = {duration: 300}); Var origpos = new THREE.Vector3 (). Copy (camera. Search); // Original position var origotot = new three.Euler (). Copy (camera.rotation); // Original rotation camera.position.set (dstpos.x, dstpos.y, dstpos.z); Camera.lookAt (dstlookat); Var dstrot = new three.Euler (). Copy (camera.rotation) // Reset original position and rotation camera.position.set (origpos.x, origpos.y, origpos.z); Camera.rotation.set (origotot.x, origotot.y, origotot.z); // // Tiving // // status new TWEEN.Tween (camera.position) .to ({x: dstpos.x, y: dstpos.y, z: dstpos.z}, options.duration). Start () ;; // rotation (using slrap) (function () {var qa = camera.quaternion; // source quaternion var qb = new three quarters.) SetFromEuler (dstrot); // dst quaternion var qm = new three Quarteran (); Var O = {T:} New TWEEN.Tween (O) .to ({T: 1}, options.duration) UpUpdate (function () {THREE.Quaternion.slerp (qa, qb, Qm, ot); camera.quarean.set (qm.x, qm.y, qm.z, qm.w);}). Start ();}). Call (this); }

It works great:

The only problem is for rotation does not seem linear ...

Thank you

In your code 

  // rotation (using slerp) (function () {var qa = camera.quaternion; // Src quaternion

to change it 

 qa = new three.Quaternion () .copy (camera.quaternion); // src quaternion

The way you do this, Qi is similar to the camera Quaternion, And this slurp comes back to Calcus. This is a steady variable Should Ona.

html - CSS autoheight, but fit content to height of div -

I have a div in which there are three children- div in the left and middle div: float: left while true: float: true because it is my layout Actually will spoil, I've used ClearFix Hack: .cf {zoom: 1; }. Cf: First,. Cf: {content: ""; Display: Table; }. Cf: After {clear: both; } It still works, but I want to be the right div an indicator. So it should fill 100% of the parent unit of height. How can I complete this? PS is the full code: & Lt; / Div & gt; & Lt; Div class = "mobile_content" & gt; & Lt; H5 & gt; {{Data.titel}} & lt; / H5> & Lt; Table & gt; & Lt; TR & gt; & Lt; Th & gt; Komponist: & lt; / Th & gt; & Lt; TD & gt; {{Data.komponist}} & lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Th & gt; Instrument: & lt; / Th & gt; & Lt; TD & gt; {{Data.instrumente}} & lt; / TD & gt; & Lt; / TR & gt;...

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName (). ToUtf8 ().
