Function Documentation

lua_to_graphite_mat_vec()

bool OGF::GOMLua::lua_to_graphite_mat_vec	(	lua_State *	L,
		int	index,
		Any &	result,
		MetaType *	mtype
	)

Converts a Lua object into a Graphite vec or mat type.

Works with vec2, vec3, vec4 of doubles and integers, and with mat4 of doubles.

Parameters

[in]	L	a pointer to the Lua state
[in]	index	the index of the Lua object to be converted
[out]	result	the result, as an Any
[in]	mtype	a pointer to the expected meta-type

Return values

true	if conversion was successful
false	otherwise

lua_to_graphite_vec2i()

bool OGF::GOMLua::lua_to_graphite_vec2i	(	lua_State *	L,
		int	index,
		vec2i &	result
	)

Converts a Lua object into a Graphite vec2i.

Parameters

[in]	L	a pointer to the Lua state
[in]	index	the index of the Lua object to be converted
[out]	result	a reference to the result, as an vec2i

Return values

true	if conversion was successful
false	otherwise

push_mat_vec()

bool OGF::GOMLua::push_mat_vec	(	lua_State *	L,
		const Any &	matvec
	)

Pushes a Graphite object onto the Lua stack.

Works with vec2, vec3, vec4 of doubles and integers, and with mat4 of doubles.

Parameters

[in]

matvec

the input vec or mat stored in an Any

Return values

true	if conversion was successful
false	otherwise
