a question about ceiusm add movie

I am currently using cesium take to create a system, but ran into a problem: I want to load similar (http://www.meteoearth.com/#/,-16.82,36.73,14.86,4,1,1,0 dynamic layers 0,0, time = 1457659440) in cloud, wind wide lines, because I want to control the dynamics of these layers, so can not use the service to publish a map layer mode to load layers, I would like is to load a transparent background transparent tiff image or movie, but after loading the cesium tiff will default into png, a transparent canvas of the movie will be similar to the canvas blocked, so that their bottom color can not achieve transparency. And I also tested czml to achieve the above effect, but the efficiency is a very serious problem. I would like to ask you to which there is no good solution. For taking up a little of your time he said he was very sorry. Thank you for viewing.


I’m not quite sure what you are asking, but here are some things that might be useful.

Check out this demo of a video material: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Video.html&label=Showcases

You could try using that for a Rectangle to put a video on the globe surface.

We also recently fixed a bug with transparent PNG materials drawing the transparent parts black. We added a transparent property, which you can set to true to draw the PNG correctly.

Here is an example:

rectangle : {
coordinates : Cesium.Rectangle.fromDegrees(-100.0, 30.0, -90.0, 40.0),
material : new Cesium.ImageMaterialProperty({
image: ‘…/images/Cesium_Logo_Color_Overlay.png’,
transparent: true




Hi,did you complete that?
