I am trying to controlling the flow of an 3D animation on unity through the sound.
Therefore, through a synthesizer sounds, get the BPM of a song, which are stored in a file. Txt, with the given time and the number of BPM in second. Then in Unity, I have a pre-defined animation, and already carry the file with the information of BPM, but now I do not know how I can make the animation speed is controlled by the information in that file.
Any idea?
You can always change AnimationState.speed to serve that purpose.

Good evening all;
I am continuing working on a project, which is essentially a drum machine whose tempo you can adjust in real time using a slider. That is, you can set up the drum machine and play it and as it's playing you can use a slider to affect its tempo in real-time. I successfully coded this in Processing 3 and 4, but I want to have it available on the web via p5.js, but am having some difficulty... I have gotten the drum machine setup in p5.js using Tone.js and WAAClock, but because I've set up the bpm variable in Setup() via a clockSetup() function (without otherwise I cannot get the drum machine to work), I can't use a slider to change the tempo in real-time. Is there a way to affect the tempo, which is currently set to 60bpm, using a slider?
To use the drum machine, click on a square that you want to activate per the row item (e.g., bottom row is the Bass Drum, the middle row is the Snare Drum) and then press the spacebar.
Here is the code on OpenProcessing: https://openprocessing.org/sketch/1734625
Apologies if this is not the right way to request assistance, still new to asking for support. :)
Also, to note, I'm using Tone.js instead of p5.sound, because Tone.js uses less RAM. p5.js causes the Sketch to crash within a minute of running the drum machine, but with Tone.js, I can run it for hours.
I tried to adjust 'bpm' in draw(), in a function, and to remove it from setup() and try to only set it up in draw(), but haven't been able to figure it out.
Is there any possibility to define a timewindow for an animation of KML objects? Like if i have to occurences animated (polygon 1 appears on the 1/1/2018 and polygon 2 on the 6/10/2018). Is there any way to define that the whole animation should last for f.e. 30 or 45 seconds? I only see that Google Earth always interpolates the animation time depending on the given
<TimeSpan> <begin> 2004-03 </begin> <end>2004-04</end></TimeSpan>
dates of the document.
In the current Google Earth Pro interface, there is no way to specify the duration (in playback-time) of an animation like this. As you noted, it expands the time slider to include the dates & times from all loaded KMLs, and plays across the slider at a preset speed (adjustable in the slider settings).
One way you could apply time playback with precise control is to set up a KML Tour which animates between two views (with time tags applied), over a specific number of seconds. Then you could have your user play it back using the Tour interface instead, and see the timing you want. Unfortunately KML Touring is rather complex with a long learning curve. There are simple things you can do (possibly including something like your request) using the tour recording interfaces in Earth Pro, but to really harness the full power of touring you'll need to create custom KML code, so consider yourself warned. :-)
I am developing an aframe project on my MacBook pro, late 2013. When running the project, the fan of my computer always spins fast, regardless which browser I use (firefox, safari, chrome) and the project size (also happens with a project just containing a simple a-box).
aframe-stats show me that my project (1028244 vertices, 342748 faces) still runs with 20 fps.
Is it somehow possible to limit the frame rate to 10fps in order to keep my computer quite? Or any other way to limit the flop-consumption of the aframe project? I already tried a native approach with sudo cputhrottle plugin-container 10 but that did not just throttle the aframe-renderer but the whole firefox browser. Can I pull the break somewhere in the JavaScript or the Browser settings?
It's difficult to say without your project code. Large data sets will simply crank out even a high spec macbook pro. I have found it helpful to pause any rendering whenever possible to quiet the users' machines.
I personally removed automated next animation frame rendering in favor of waiting for controls and objects to change.
For example:
this.controls.addEventListener( 'change', function(e){ addToRenderStack(); });
A simple function addtorenderstack puts in a new value in a list for a render, with the expectation that the render will occur at some point in the future and not right away. the list can also be used to log who requested the render in the call stack, and narrow down performance hogs.
addtorenderstack places a render request in a list. In the requestanimationframe loop, if the list has any length, a render is called on the scene. The stack is immediately cleared rather than processed one by one. If controls or animations continue to make render requests, the list will have a length again and request animationframe will process them in the same way with another render.
In this way, the code only renders when absolutely required. This saved me much grinding on framerate and the fans only come on during intensive operations and then shutdown when its complete, much like a typical 3d game experience.
Your mileage may vary depending on what's happening in your app. I work in engineering so often the view of the 3d world is stopped as an engineer examines or shows a model.
I have a custom UISlider and use the currentPlaybackTime to change values of an MPMoviePlayerController object.
The problem is when i scrub at a fast rate using the slider, it doesn't respond as fast as i would like..
Is there any better way to have a fast interactive scrubber for ipad? targeting from OS 3.2
Well there are two issues, only one you can control directly.
Multimedia-content is commonly compressed using some kind of delta-compression, hence quick and exact seeking is not a trivial task to cope with. As that is common and since you can not directly change that, you will have to live with it.
the only way to increase responsiveness for seeking on the content-side (when encoding) is reducing the gop-size - that is, less p-frames between the i-frames.
when using a slider or a similar control, you could, instead of directly connecting the current playback position with it, handle any manual changes in an indirect fashion. You could run a timer based job that, whenever the slider/scrubber has been moved, tries to adjust the playback position towards that new value. Once the player is seeking, prevent the scrubber from getting feedback from the current playback location but allow it once the player is in playing state again. That way the user does not directly experience the clunky seek feedback.
I want to make a simple assistant for putting together AviSynth scripts. This would be a windows desktop application that would have a "preview" screen of an avi movie, which would give you a timeline, play, fast-forward, rewind, advance and go back frame-by-frame. The program would need to know the frame number of the current frame in the player and its filename.
What language is best suited for this? I know PHP ( I understand that this is not a contender ) and am familiar with Java. My thought is that the biggest hurdle with this project will be finding a library for the video playing features. With a cursory glance, no Java video libraries jumped out at me. My next thought would be c++ for this.
The output of this program would be an AviSynth script, a plaintext file which looks like this:
AviSource("myAvi.avi")
Crop(0, 0, 320, 240)
Blur(0.1)
There are a few tool kits that can do tihs:
C#: DirectShow (DirectX)
Java: JMF
If you have Avisynth installed, the only thing you need for preview (If I understood, that's your need) is something that can decode uncompressed video. It would open like a normal file. I'm sure there are video players implemented fairly well in Java, but I don't know how much functionallity from them you need. Anyway parsing scripts is not easy - I recommend you not to try to if you don't need to.
EDIT: I'm sorry, I thought you needed a very specific app, but from what you seem to need, you don't need to code anything, use AVSP!
Please watch this video, it shows how straightforward it is. It has advanced functions such as auto-completion, (even from your own auto-loading scripts!) syntax coloring, macros, automtic importing, drag&drop (of a video, for instance - just drag it to the video and AVSP makes the loading) scrit preview with zoom and all stuff, you can use automatic or custom sliders (you can make a slider that re-writes a number on the script in real time, for instance for hue/luminosity/contrast/etc. that would be cumbersome to control via script), checkboxes & radio buttons (for boolean values, etc...), text fields that alter strings in real time, and basically anything you need... Please check it out.
Also, VirtualDubMod is OLD.
And yep, AVSP is free, both gratis and libre! =)
