label : HeightReference.CLAMP_TO_GROUND "An error occurred while rendering." #6793

yijiao19 · 2018-07-11T09:40:16Z

Today I update cesium 1.47 instaed 1.43.
But when I add a label with "heightReference: Cesium.HeightReference.CLAMP_TO_GROUND", the chrome reports me the text :

An error occurred while rendering. Rendering has stopped.
RuntimeError: Program failed to link. Link log: Could not pack varying v_logZ
Note: Additional non-conformant packing restrictions are enforced on D3D9.

my test code:

var viewer = new Cesium.Viewer('cesiumContainer', {
    terrainProvider: Cesium.createWorldTerrain()
});
viewer.scene.globe.depthTestAgainstTerrain = true;

var e = viewer.entities.add({
    position : Cesium.Cartesian3.fromDegrees(-122.1958, 46.1915),
     label : {
        text : 'Clamped to ground',
        heightReference : Cesium.HeightReference.CLAMP_TO_GROUND,
        horizontalOrigin : Cesium.HorizontalOrigin.CENTER,
        verticalOrigin : Cesium.VerticalOrigin.BOTTOM,
        fillColor : Cesium.Color.BLACK,
        showBackground : true,
        backgroundColor : new Cesium.Color(1, 1, 1, 0.7),
        backgroundPadding : new Cesium.Cartesian2(8, 4)
    }
});

viewer.trackedEntity = e;

Hi @yijiao19,

Cesium 1.45 added a logarithmic depth buffer, disabling it might help for now. Here's your code with log depth disabled on Sandcastle.

More technically, it's possible that you're running up against WebGL limits for your browser and graphics hardware when logarithmic depth is enabled. Can you attach a PDF of the results from webglreport.com?

hpinkos · 2018-07-11T15:00:42Z

Hi @yijiao19, I was unable to reproduce this. Do you see this crash in Cesium 1.46 too? Also, check to make sure Chrome is up to date, and try updating drivers for graphics card.

And as @likangning93 said, please send us the results from webglreport.com

yijiao19 · 2018-07-12T08:37:20Z

@likangning93 Thanks! I set logarithmicDepthBuffer=true, then fix the bug.

Chrome is the latest version. I guess my graphics hardware may be not available for webGL 2.0.

likangning93 · 2018-07-12T13:56:23Z

Hi @yijiao19, can you post a higher-resolution screenshot or preferably a PDF for the webgl 1 page on webglreport? Chrome and Firefox both allow using ctrl + p to print a webpage, and there should be an option to create a PDF instead of a printout.

shunter · 2018-07-12T13:59:52Z

WebGLReport is designed specifically so that you can easily copy/paste the page as text into notepad. ctrl-a, ctrl-c, ctrl-v into notepad. then copy/paste here.

yijiao19 · 2018-07-13T01:52:14Z

Hello @likangning93

Sorry, I try my best but the pdf of Chrome is confusing. So I also send you a higher-resolution screenshot of the page in chrome.

Hi @yijiao19,

Thanks for the info! It looks like your graphics card should be able to run Cesium's newer features pretty well, but it's using old drivers since there's only support for D3D9.
Is it possible for you to update your graphics driver?

See here: http://www.nvidia.com/Download/index.aspx?lang=en-us

For your GPU, Product Type should be Quadro. Then, you'llhave to go to Product Series, select Show all Product Series, and then select Quadro NVS Series (Notebooks). It looks like you're using the NVS 5400M under Product.

The automatic detection thing might work too, but I haven't tried it.

hpinkos · 2018-07-13T17:25:22Z

I'm going to close this issue since it seems like an problem with the graphics driver, not a bug in Cesium. @yijiao19 if you update your drivers and you still see this crash, feel free to reopen this issue. Also try clearing your cache/cookies in case there's something cached from the older version of Cesium that's causing issues.

I'm thinking the issue is that the WebGL report @yijiao19 posted says Max Varying Vectors: 9. With the depth testing changes BillboardCollection could have 8 varyings. This should be fixed by #6781 in many cases, but I'll have to see about packing things better for the case where vertex shader texture reads aren't available and the max varyings is low.

Hi @lftgly, are there updated graphics drivers available for your Windows 7 setup? We might be running up against your machine's varying limit as @hpinkos mentioned above, but a driver update (if available) could be a workaround. Related, do you know what the GPU model number (like HD 4000) or CPU model number (i5-3320m) is? The oldest Intel graphics I have on-hand is the HD 4000 from 6 years ago, which seems to be able to handle this feature when running with up-to-date drivers.

For iOS though, I'm seeing only 8 available varying vectors on a first-gen iPad Pro... this should be kind of representative, Apple seems to try to keep the capabilities available to WebGL consistent across iOS device generations.

@lftgly can you see if you still have this problem in our current master branch? Here's a zip file to download a build: http://cesium-dev.s3-website-us-east-1.amazonaws.com/cesium/master/Cesium-1.47.0-master27825.zip
