Hardware acceleration for OpenGL?

[Kaha]

Hi,

Based on the ogldraw example project, I've written a fairly complex model using low-level OpenGL calls.  The model needs to change as incoming telemetry data is received, and I do this by refreshing the drawing as fast as possible. 

I can only get a rendering speed of about 3 frames/second.  It appears the CPU is fully loaded.  Calls to glGetString(GL_VENDOR) and glGetString(GL_RENDERER) return:  Microsoft Corporation and GDI Generic, respectively.  This seems to indicate the rendering is done with software emulation, even though I have a high-end 3D graphics video card installed.   

Does LabWindows OpenGL plugin only use software emulation or is there a setting I need to turn on to enable hardware acceleration?

Hi Kevin,

The CVI OpenGL plugin does not take advantage of hardware acceleration.  However, the 3D graph that ships with CVI does so you may want to look into that for your application.  I hope this helps!
