Greetings All! I hate to come up with another stupid one, but I've been banging my head with this one!
One of the displays I doing has an ellipsoid globe appearing and above that, I have some Overlay lines (what we call MOA lines) or marker lines. I have them drawn above the globe and from a normal view the lines and polygons appear as they should. Note: I'm using a camera that is using the terrain manipulator to control so I can zoom in and out move east west north south. I'm using: Code: linesOverlay->addPrimitiveSet(new osg::DrawArrays(GL_LINE_LOOP,0,numPts)); to draw the line loop and Code: linesOverlay->addPrimitiveSet(new osg::DrawArrays(GL_POLYGON,0,numPts)); to draw a filled polygon. linesOverlay is a Geometry class and I'm adding it to a Grode using the addDrawable command. Well, I noticed that when I zoom in on the polygon. that it appears normal, but using the same data points for drawing a line loop, when I zoom in on a line, I will get to within 2000 meters of the line and it will start disappear. first at the middle of the focus point of the camera, then outward as I continue to zoom in! Note: I had similar problem with my polygon elements that seem to be getting cut off by my near camera plane. I readjusted the near/far ratio that seemed to fix it, but maybe that was the wrong approach? FYI: I'm using OSG 2.8.1 I must be goofing up someware! Any Ideas? Grin! ...
