We have run into an issue using textured terrain files under the MacOS that have been created using the osgdem utilities of Virtual Planet Builder. The terrains have been created on both Linux and the Mac directly and display OK under Linux. On the Mac we are seeing the following error when displaying the terrain file “Warning: detected OpenGL error ‘invalid operation’ at after RenderBin::draw(..)”. The terrain is displayed but no texture is displayed.
We have a cross platform software system developed for solar system scale visualization of spacecraft systems that runs under Windows, Linux and Mac. The Mac port is a recent addition. We provide the ability to have terrain for planets and moons. These terrain files are working fine under Windows and Linux, but are not displaying properly (as described above) on the Mac. We are using OSG 3.4 and VPB-master as of that release. We have created terrain files on both the Linux and Mac systems with the resultant model files working on Linux, regardless of where the files were created. Neither work on Mac properly. The Mac Laptop is running 10.12.6 Sierra with a GeForce GT750M 2G graphics card. Some additional information: Other model files of all different formats seem to work fine on the Mac including ive, osgb, flt, fbx, and obj. These models display fine with their textures on the Mac. A simple test we ran was downloading the Blue Marble imagery, specifically world.topo.bathy.200410.3x5400x2700.jpg and created a whole earth model using “osgdem --terrain --geocentric --radius-polar 6371000 --radius-equator 6371000 --whole-globe -t world.topo.bathy.200410.3x5400x2700.jpg –l 4 -o wholeEarthBlueMarbleTest.ive”. This displays fine on our Linux machine but not the Mac. We created the terrain on both machines for testing purposes. We have also added the texture type options, trying compressed, rgba-compressed, rgba, rgb-16. Any insight into this problem would be appreciated. Thanks... D.J.
