Realtime shaders need two components:
• The User Interface, which is defined by a SPDL file. A single dynamic library can contain multiple shader implementation. However, the SPDL file can only describe one shader. See Generate the SPDL file for information on creating the SPDL file.
• The implementation code, which is compiled in a dynamic library. See Realtime Shader Callback Reference for details
Once these components are in place, you can install the shader in Softimage to test it. See Register the Shader for details.
