Hi,in ArcGlobe, I???m drawing geometry positioned at point features. This is done through OpenGL and works quite well except that the geometry is not drawn exactly at the point feature symbol but a meter or so aside. Basically I compute the geocentric position of a feature point like that: m_globeViewUtil.GeographicToGeocentric(
point.X, point.Y, elevationMeters,
out glX, out glY, out glZ);
The rendering is done in OnAfterDraw: GL.glPointSize(15.0f);
GL.glColor3ub(255, 0, 0);
GL.glBegin(GL.GL_POINTS);
GL.glVertex3f((float)glX, (float)glY, (float)glZ);
GL.glEnd();
With this sample code, the red point drawn by OpenGL is a few meters away from the feature points symbol. Depending on the location on earth, the distance varies. The real render code uses the geocentric position as origin for 3d models. [ATTACH=CONFIG]18240[/ATTACH]This happens in ArcGlobe 10.0 and 10.1. C# is used as development language. Does somebody know how to make the symbol and the drawn geometry coincide?
