Detailed Description

Class representing a context for closure evaluation. On hardware BSDF closures are evaluated differently in reflection, transmission or environment/indirect contexts. This class represents the context we are in and if extra arguments and function decorators are needed for that context.

Member Typedef Documentation

using ClosureContext::Argument = std::pair<const TypeDesc*, string>

An extra argument for closure functions. An argument is a pair of strings holding the 'type' and 'name' of the argument.

Definition at line 253 of file GenContext.h.

using ClosureContext::Arguments = vector<Argument>

An array of arguments.

Definition at line 255 of file GenContext.h.

using ClosureContext::ClosureParams = std::unordered_map<string, const ShaderInput*>

Extra parameters for closure evaluation.

Definition at line 258 of file GenContext.h.

void ClosureContext::addArgument	(	const TypeDesc *	nodeType,
		const Argument &	arg
	)

inline

inline

Return the identifier for this context.

Definition at line 265 of file GenContext.h.

void ClosureContext::setClosureParams	(	const ShaderNode *	closure,
		const ClosureParams *	params
	)

inline

Set extra parameters to use for evaluating a closure.

Definition at line 294 of file GenContext.h.

void ClosureContext::setSuffix	(	const TypeDesc *	nodeType,
