Detailed Description

abstract base classs for any object that can store variables and write itself into a device-side shader binding table (ie, raygen programs, closest hit programs, etc. Each SBTObjectBase has a type that describes its variables, but the actual work for subclasses of this type will be done in the subclass.

Constructor & Destructor Documentation

◆ SBTObjectBase()

owl::SBTObjectBase::SBTObjectBase	(	Context *const	context,
		ObjectRegistry &	registry,
		std::shared_ptr< SBTObjectType >	type
	)

create a new SBTOBject with this type descriptor, and register it in that registry

Member Function Documentation

◆ getVariable()

Variable::SP owl::SBTObjectBase::getVariable ( const std::string & name )

inline

return shared-ptr to this variable - should only be called for variables that we actually own

◆ hasVariable()

bool owl::SBTObjectBase::hasVariable ( const std::string & name )

inline

returns whether this object has a variable of this name

◆ writeVariables()

void owl::SBTObjectBase::writeVariables	(	uint8_t *	sbtEntryBase,
		const DeviceContext::SP &	device
	)		const

this function is arguably the heart of the owl variable layer: given an SBT Object's set of variables, create the SBT entry that writes the given variables' values into the specified format, prorperly translating per-device data (buffers, traversable) while doing so (also works for launch params, even though those, strictly speaking, are not part of the SBT)

Member Data Documentation

◆ type

std::shared_ptr<SBTObjectType> const owl::SBTObjectBase::type

our own type description, that tells us which variables (of which type, etc) we have

◆ variables

const std::vector<Variable::SP> owl::SBTObjectBase::variables

the actual variable values

The documentation for this struct was generated from the following files:
