Detailed Description

base class for describing the 'type' (eg, set of named variabels, progrma name, etc) of anything that can store variables, and that will eithe be written into the SBT, or other device representations. Object types store the description of objects (eg, which variables they have, and how those are layouted in device memory, while actual objects (basically, the equivalent of C++ instances of tihs type) then store the values* for the given type

Constructor & Destructor Documentation

~SBTObjectType()

owl::SBTObjectType::~SBTObjectType ( )

virtual

clean up; in particular, frees the vardecls

Member Function Documentation

declareVariable()

void owl::SBTObjectType::declareVariable	(	const std::string &	varName,
		OWLDataType	type,
		size_t	offset
	)

add a new variable of given type and name, and with given byte offset within the device representation of this class

getVariableIdx()

int owl::SBTObjectType::getVariableIdx

(

const std::string &

varName

)

find index of variable with given name, or -1 if not exists

hasVariable()

bool owl::SBTObjectType::hasVariable

(

const std::string &

varName

)

check if we have this variable (to error out if app tries to set variable that we do not own

instantiateVariables()

std::vector< Variable::SP > owl::SBTObjectType::instantiateVariables

(

)

create a set of actual instances of the variables of this type, to be attached to an actual object of this type, so this object can then store variable values

create one instance each of a given type's variables

toString()

std::string owl::SBTObjectType::toString ( ) const

overridevirtual

pretty-printer, for printf-debugging

pretty-typecast into derived classes

Reimplemented from owl::ContextObject.

Reimplemented in owl::SphereGeomType, owl::TrianglesGeomType, and owl::UserGeomType.

Member Data Documentation

varDecls

const std::vector<OWLVarDecl> owl::SBTObjectType::varDecls

the high-level semantic description of variables in the variables struct

varStructSize

const size_t owl::SBTObjectType::varStructSize

the total size of the variables struct
