Name
cgGetNumDependentStateAssignmentParameters - get the number of effect
parameters on which a state assignment depends
Synopsis
#include <Cg/cg.h>
int cgGetNumDependentStateAssignmentParameters( CGstateassignment sa );
Parameters
- sa
-
The state assignment handle.
Return Values
Returns the number of parameters on which sa depends.
Description
State assignments in CgFX passes may include references to one or more
effect parameters on the right hand side of the state assignment that are
used for computing the state assignment's value.
cgGetNumDependentStateAssignmentParameters returns the total number of
such parameters. cgGetDependentStateAssignmentParameter can then be
used to iterate over these parameters.
This information can be useful for applications that wish to cache the
values of state assignments for customized state mangement so that they
can determine which state assignments may change as the result of changing
a parameter's value.
Examples
to-be-written
Errors
CG_INVALID_STATE_ASSIGNMENT_HANDLE_ERROR is generated if sa is not a valid state assignment.
History
cgGetNumDependentStateAssignmentParameters was introduced in Cg 1.4.
