In a viewport, click the display type (for example, Wireframe) and then choose Realtime Shaders > MyCustomPass. Show me

After you select MyCustomPass, the MyClearScreenBuffer display callback changes the background color.

Building the C++ Example

The Softimage SDK includes a compiled version of SampleDisplayCallback. If you want to modify the code, you can rebuild the example by following these instructions.

To build the example on Windows

Open an Softimage command prompt, and type devenv to start Visual Studio .NET.

Starting Visual Studio .NET from an Softimage command prompt ensures that environment variables such as XSISDK_ROOT are set (otherwise you'll get build and link errors).

Tip To load the SampleDisplayCallback project from the command line, type:
```
devenv SampleDisplayCallback.vcproj
```
In Visual Studio .NET, open the project file .vcproj.
Select a configuration (Win32 Release or Win32 Debug) and build the DLL.

To build the example on Linux

In a shell (tcsh) window, type:
```
source $XSI_HOME/.xsi_<xsi_version>
```
Change directories to
```
cppsrc
```
To remove all intermediate files before building the example, run this command:
```
gmake clean
```
To compile the example, run this command:
```
gmake
```
