Function Documentation

sortObjectsByDepth()

void NAPAPI nap::sorter::sortObjectsByDepth	(	std::vector< RenderableComponentInstance * > &	comps,
		const glm::mat4 &	viewMatrix
	)

Sorts a set of renderable components by layer, then distance to the camera, ie: depth Note that when the object is of a type mesh it will use the material to sort based on opacity If the renderable object is not a mesh the sorting will occur front-to-back regardless of it's type as we don't know the way the object is rendered to screen

Parameters

comps	the renderable components to sort
viewMatrix	the camera view matrix used for sorting based on distance

sortObjectsByZ()

void NAPAPI nap::sorter::sortObjectsByZ

(

std::vector< RenderableComponentInstance * > &

comps

)

Sorts a set of renderable components by layer, then location on world z-axis (ignores camera view transformation) Note that when the object is of a type mesh it will use the material to sort based on opacity If the renderable object is not a mesh the sorting will occur front-to-back regardless of it's type as we don't know the way the object is rendered to screen

Parameters

comps

the renderable components to sort
