Name

cgD3D11GetLatestGeometryProfile - get the latest supported geometry shader version

Synopsis

#include <Cg/cgD3D11.h>

CGprofile cgD3D11GetLatestGeometryProfile( void );

Parameters

None.

Return Values

Returns the latest geometry shader version supported by the current D3D device.

Returns CG_PROFILE_UNKNOWN if no D3D device is currently set.

Description

cgD3D11GetLatestGeometryProfile retrieves the latest geometry shader version that the current D3D device supports. This is an expanded interface function because it needs to know about the D3D device to determine the most current version supported.

Starting in Cg 3.0, if the environment variable CGD3D11_LATEST_GEOMETRY_PROFILE is set in the application's environment to a string that cgGetProfile translates to a valid profile (meaning not CG_PROFILE_UNKNOWN), then it is this CGprofile value that will be returned by cgD3D11GetLatestGeometryProfile.

Examples

  CGprofile bestGeometryProfile = cgD3D11GetLatestGeometryProfile();

Errors

None.

History

cgD3D11GetLatestGeometryProfile was introduced in Cg 3.0.
