Available on crate feature SCNShadable only.

The SCNProgramDelegate protocol declares the methods that an instance of SCNProgram invokes to delegate the binding of parameters.

Provided Methods

unsafe fn program_bindValueForSymbol_atLocation_programID_renderer( &self, program: &SCNProgram, symbol: &NSString, location: c_uint, program_id: c_uint, renderer: &SCNRenderer, ) -> bool

where Self: Sized + Message,

👎Deprecated: Use -[SCNShadable handleBindingOfSymbol:usingBlock:] instead

Available on crate feature SCNRenderer only.

Invoked on the delegate to let it bind program values and/or also bind associated graphics resources (such as textures).

Parameter program: The program to bind values for.

Parameter symbol: The name of the symbol to bind a value for.

Parameter location: The location of the symbol within the program object to be modified.

Parameter programID: The program object.

Parameter renderer: The renderer that is currently rendering the scene.

unsafe fn program_unbindValueForSymbol_atLocation_programID_renderer( &self, program: &SCNProgram, symbol: &NSString, location: c_uint, program_id: c_uint, renderer: &SCNRenderer, )

where Self: Sized + Message,

👎Deprecated: Use -[SCNShadable handleUnbindingOfSymbol:usingBlock:] instead

Available on crate feature SCNRenderer only.

Invoked on the delegate to let it unbind program values and/or also unbind associated graphic resources (such as textures).

Parameter program: The program to unbind values for.

Parameter symbol: The name of the symbol to unbind a value for.

Parameter location: The location of the symbol within the program object to be modified.

Parameter programID: The program object.

Parameter renderer: The renderer that is currently rendering the scene.

unsafe fn program_handleError(&self, program: &SCNProgram, error: &NSError)

where Self: Sized + Message,

Invoked on the delegate whenever a compilation error occurs.

Error domain is SCNErrorDomain.

Parameter program: The program that generated a compilation error.

Parameter error: The compilation error.

unsafe fn programIsOpaque(&self, program: &SCNProgram) -> bool

where Self: Sized + Message,

👎Deprecated: Use SCNProgram.opaque instead

The delegate should implement this mehod and return NO if the fragments generated by the program are not opaque.

Parameter program: The queried program.

This is deprecated. Use SCNProgram’s opaque property instead.
