As I understand FX using Niagara won't be visible in Editor while using Path Tracer but as per Unreal Engine documentation it will be revealed in Movie Render Queue render.
Dynamic Scene Elements
The Path Tracer works by having the renderer accumulate samples over time. This is ideal for static scenes and less so for dynamic scenes that include elements such as moving lights, animated skinned meshes, and visual effects. These types of elements do not invalidate path tracing in the editor and appear as blurred, or streaking artifacts in the frame. This only appears when working in the editor and is remedied by using the Movie Render Queue to render out final elements.

Does that mean FX using Niagara will be rendered using Path Tracer in Movie Render Queue?

I want to create a motion of electrons moving along a wire in create js Adobe animate, have tried some other Js providers but it either too complicated for my needs or a bit costly for a small project.The code I am using is below:
createjs.MotionGuidePlugin.install();
Using a Motion Guide
createjs.Tween.get(target2&target1).to({guide:{ path:[0,0, 0,400,400,400, 600,100,0,0] }},7000);
// Visualizing the line
graphics.moveTo(0,0).curveTo(0,200,200,200).curveTo(200,0,0,0);
This works fine for one object but to do many like electrons following a wire path does not seem to work,as it only allows one target on the path. Is there another way I can accomplish this, I am using Adobe animate CC HTML 5
Thanks all for your time

I have an application that uses Qt 5.6 for various purposes and that runs on an embedded device. Currently I have it rendering via eglfs to a Linux frame buffer on an attached display but I also want to be able to grab the data and send it to a single-color LED display unit (a device will either have that unit or a full video device, never both at the same time).
Based on what I've found on the net so far, the best approach is to:
turn off anti-aliasing;
set Qt up for 1 bit/pixel display device;
select a 1bpp font, no grey-scale allowed; and
somehow capture the graphics scene that Qt produces so I can transfer it to the display unit.
It's just that last one I'm having issues with. I suspect I need to create a surface of some description and inject that into the Qt display "stack", but I cannot find any good examples on how to do this.
How does one do this and, assuming I have it right, is there a synchronisation method used to ensure I'm only getting complete buffers from the surface (i.e., no tearing)?
I am dynamically creating some controls in a page. it will become slow when we have some fifty controls.
what are the code optimization techniques/ guideline used in extjs?
Is there any specific methods which will slow down the entire loading?
Sencha has great posts:
Ext JS 4.1 Performance about:
Network latency which affects initial startup time heavily, but also data store load time.
CSS processing.
JavaScript execution.
DOM manipulation.
Optimizing Ext JS 4.1-based Applications about optimization tips and the Page Analyzer tool.
My tips are
Use Ext.container.Container rather than Ext.panel.Panel.
Instead of adding ext components, use XTemplate with data view to load similar controls.
if you are using many images then use image sprites - An image sprite is a collection of images put into a single image. A web page with many images can take a long time to load and generates multiple server requests.
Using image sprites will reduce the number of server requests and save bandwidth.

I have a project in which I would like to programatically create and render a 3d animation based upon input. I originally asked here on stackoverflow if Blender was right for the job, and the response was yes, but upon looking at the API, it says this:
Python was embedded in Blender, so to access BPython modules you need to run scripts from the program itself: you can't import the Blender module into an external Python interpreter.
I want to be able to create and render this scene without having to ever open another program like Blender. Is this possible, and is Blender still the right choice?
Thanks in advance!
At work me and colleague worked on a project that rendered 3d scenes altered externally. We used Python to modify/create scenes, and did the rending on server through the command line interface (no GUI).
You can pass a python script as an argument to Blender in the command line options to
generate your scene objects and do the rendering.
I don't see how you can render in Blender without using Blender.
You can use Blender if you want, obviously this is not your only option.
If you need to
create and render a 3d animation based upon input.
You can go as simple or as you complex as you'd like.
You can use OpenGL in your language of choice (C++, Java, Python, etc.)
and display the animation (with or without fancy renderings).
It's up to what 'render' means to your context.
If you need some nice shading(light, soft shadows, reflections, etc. - ray tracers basically), you can still show an interactive preview to your users and generate the scene
for a 3rd party renderer(like Yafaray, Sunflow, LuxRender, etc. - I've put together a short list of free renders), and show the progress to the users after they've chosen the external render option.
On a similar note, have a look at joons.

I've always been wondering : What librairies/APIs are used by web browser engines (Gecko, WebKit ...) to render images, text, buttons & stuff ?
Think about it, webpages are rendered pixel by pixel identically across operating systems. Yet buttons, drop lists and text look native on most platforms.
The main are
Trident (IE and derivats)
Webkit (Safari, Chrome)
KHTML (KDE Konqueror) This was the base for webkit
Presto (Opera)
You can read more here: http://en.wikipedia.org/wiki/Web_browser_engine
These engines create an object structure of the HTML and then use Components to build the page, the browser engine does not render pixel by pixel but uses buttons, comboboxes, image elements all of which in them self render to a buffer and then those imagebuffers are collapsed to the screen.
Some engines use the plattforms own components (Trident) other use their own with different skins for different plattforms.
For actual rendering I know IE uses windows controlls and Gecko as you noted uses Cairo.
I assume webkit might use gtk or qt but I am not sure and for opera I have no idea but I assume they use some form of framework or toolkit.
