Under the OpenGL 1.1 display only the first 256 characters are supported.
Under the OpenGL 4.4 display all characters in a font are supported. OpenGL 1.1 did not support underlines or strikeouts in the special OpenGL Microsoft font functions. The OpenGL 4 display font support will work with underlines and strikeout fonts for labels. Due to display limitations of clean line drawing, OpenGL 1.1 displayed the hidden line sections behind hills. The “hidden lines” are those that should not display in 3D because they go behind the terrain such as the sections of contours behind hills. 3D Contours with “hidden lines” will draw correctly in OpenGL 4.4. Visible differences between OpenGL 1.1 and OpenGL 4.4 or better: For all video cards without Video Vendor support, OpenGL 1.1 will be used exclusively. Optionally, users with cards supporting OpenGL 4.4 or newer may choose to use the older OpenGL 1.1. Opengl 4.4* drivers#
Video cards with Video Vendor drivers supporting OpenGL versions 4.4 or newer may use the OpenGL 4.4 support. The LP360 for ArcGIS extension now supports OpenGL 1.1 only to remain compatible with ArcMap OpenGL limitations. Both the LP360 standalone and Topolyst products now support two versions of OpenGL, OpenGL 4.4, or better if available, and OpenGL 1.1 are supported for these two products. OpenGL 1.0 was released on Windows in 1994.
Previous versions of LP360 supported OpenGL 1.0 only.
