| Shader library
| Pixie comes with a library that allows you to query a compiled shader for its parameter. SDR lib exports the following two functions: TSdrShader *sdrGet(const char *); void sdrDelete(TSdrShader *); The first function is used to get the shader info i.e.: sdrGet("matte.sdr"). The second function can be used to free the structure returned be sdrGet. The structure TSdrShader contains the shader and parameter information. See the source code for "sdrinfo" for example usage. The structure TSdrShader is defined as: typedef struct TSdrParameter { char *name; // Name of the parameter ESdrType type; // Type of the parameter ESdrContainer container; // Container class of the parameter int numItems; // Number of items (the number of items if an array, 1 otherwise) char *space; // The space that the default value is expressed in UDefaultVal defaultValue; // The default value struct TSdrParameter *next; // The next parameter } TSdrParameter;
