Name

cgD3D9GetLatestVertexProfile - get the latest supported vertex shader version

Synopsis

#include <Cg/cgD3D9.h>

CGprofile cgD3D9GetLatestVertexProfile( void );

Parameters

None.

Return Values

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

Returns CG_PROFILE_UNKNOWN if no D3D device is currently set.

Description

cgD3D9GetLatestVertexProfile retrieves the latest vertex 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 2.2, if the environment variable CGD3D9_LATEST_VERTEX_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 cgD3D9GetLatestVertexProfile.

Examples

  CGprofile bestVertexProfile = cgD3D9GetLatestVertexProfile();

Errors

None.

History

cgD3D9GetLatestVertexProfile was introduced in Cg 1.1.
