Members

Member	Description
driver_type	A value that describes the quality of the OpenGL driver. Possible values are shown in the table below this table.
vendor	Hardware vendor of the OpenGL driver (i.e. "ATI Technologies Inc.")
driver	Name of the OpenGL driver (i.e. "Radeon x600 PRO x86/SSe2")
version	A version string associated with the OpenGL driver (i.e. "2.0.5885 WinXP Release")
glsl_supported	OpenGL Shading Language is supported if non-zero
pbuffers_supported	OpenGL pixel buffers are supported if non-zero
parallel_shadows_supported	OpenGL shadows are supported in parallel views if non-zero
perspective_shadows_supported	OpenGL shadows are supported in perspective views if non-zero
reflections_supported	OpenGL extensions that support reflections are supported if non-zero

driver_type settings:

Constant	Meaning
GLIT_HARDWARE_DRIVER	The driver is a hardware accelerated driver
GLIT_GENERIC_DRIVER	The driver is a software-based driver with poor OpenGL support
GLIT_GENERIC_ACCELERATED_DRIVER	The driver is a software-based driver partially accelerated by hardware.
