Caps.VertexShaderVersion Property |
Language: |
Retrieves a structure that indicates the main and subordinate vertex shader versions supported by a device.
Visual Basic .NET Public ReadOnly Property VertexShaderVersion As Version C# public Version VertexShaderVersion { get; } Managed C++ public: __property Version* get_VertexShaderVersion(); JScript .NET public function get VertexShaderVersion() : Version
System.Version . A Version
This property is read-only.object that indicates the main and subordinate vertex shader versions supported by the device.
Only vertex shaders with version numbers equal to or less than the value indicated by this member succeed in calls to the VertexShader constructor.
Check for Shader Support
This example shows how to check the hardware device for shader support.
To determine whether the hardware device supports shaders, Microsoft® Direct3D® allows the application to check the shader version.
To check for shader support:
- Obtain the device's capabilities by using the Manager.GetDeviceCaps method.
- Using the capabilities object obtained with the previous call, check the shader version by calling Caps.VertexShaderVersion.
[C#]
public bool CheckShaderSupport() { Version v1_1 = new Version(1,1); // check version is at least shader 1.1 // retrieve the device caps Caps caps = Manager.GetDeviceCaps(0, DeviceType.Hardware); // check the supported shader version if ((caps.VertexShaderVersion >= v1_1) && (caps.PixelShaderVersion >= v1_1)) { return true; } return false; }
