OpenGL Rendering Problems

MATLAB encountered a problem your computer's OpenGL rendering hardware. The following steps describe what you should do next:

1. Type opengl info in the Command Window.
2. If you see the following line in the returned information:

• Software = false
  

3. Then add the following command to your startup.m file:

• opengl software
  

4. If the opengl command returns only errors, put the following command in your startup.m file:

• opengl neverselect
  

1. This command disables OpenGL rendering.

See the opengl reference page for more information on these settings and other options available to you. See also startup.

Workarounds for Known Bugs

You might be able to enable software workarounds for certain OpenGL bugs. See Driver Bug Workarounds for more information.

Other Problem Solving Resources

The cause of the problem might be the graphics driver supplied with your graphics hardware. Contact your vender

Background

OpenGL is a rendering method that MATLAB uses to display graphics that have greater complexity or when you use transparency. OpenGL can use graphics hardware for accelerated performance. If your computer does not have the necessary hardware, or there are incompatibilities between graphics drivers and MATLAB, you can use a software version of OpenGL
