toggle()

MAYAFLUX_API Form< bool > MayaFlux::Portal::Forma::Geometry::toggle	(	Kinesis::AABB2D	region,
		glm::vec3	color_off = glm::vec3(0.25F),
		glm::vec3	color_on = glm::vec3(0.2F, 0.7F, 0.4F)
	)

Geometry function for a boolean toggle in NDC space.

Renders region as a filled rect in color_off or color_on based on the current bool value. Interaction is the caller's responsibility.

Parameters

region	NDC bounds of the toggle.
color_off	Fill color when false.
color_on	Fill color when true.
