SimpleOceanLayer is not working

[raghulsekar]

I created a SimpleOceanLayer instance and also passed bathymetry data using GdalElevationLayer , i have a slider to increase the sea level which will set the SimpleOceanLayer ->setSeaLevel(value) But there is no visible change in the sea level though the sea value is set.

Hello, thanks for your report. We expose the simple ocean layer, but it is part of the osgEarth software package. I can look to see if we can reproduce, but whether we can or not, we do not directly maintain the simple ocean layer driver.

I was able to add in code to change the sea level in the Ocean example in SDK. I am attaching the patch here. I see changes in the sea level immediately. Currently unable to reproduce the problem you indicate:

height.patch

0 Sea Level:

350 sea level:

As you can see there is no change here.

osgEarth::GDALElevationLayer* oceanLayer = new osgEarth::GDALElevationLayer(); oceanLayer->setName("Bathymetry"); oceanLayer->setURL("D:/GEBCO_06_Jun_2023_55b1787783c5/GEBCO_06_Jun_2023_55b1787783c5/gebco_2023_n40.0_s0.0_w60.0_e100.0.tif"); oceanLayer->setVisible(true); map->addLayer(oceanLayer);

In your example, it looks like you're zoomed out quite a bit in order to see an ocean change of 70m.

The Simple Ocean layer is basically a semitransparent plane at 0.0 height that you'll see when you zoom in fairly closely. I do not see the plane in your image and it might be because you're zoomed out quite a bit.

I also do not have your data set to try to reproduce your error, but you do have the sample code that I attached that can reproduce a working example. Is this maybe a mismatch on expectations of what the simple ocean layer driver does?

My bad i tried setting the maxVisiblerange of oceanlayer and its working now, Thanks.

Great! Thanks for the update, glad it is working for you now.
