window_coords() [4/4]

MAYAFLUX_API glm::vec2 MayaFlux::window_coords	(	double	ndc_x,
		double	ndc_y,
		double	ndc_z,
		uint32_t	window_width,
		uint32_t	window_height
	)

Convert NDC coordinates to window pixel coordinates.

Parameters

ndc_x	X coordinate in NDC space [-1, +1]
ndc_y	Y coordinate in NDC space [-1, +1] (center origin, +Y up)
ndc_z	Z coordinate (ignored, accepted for convenience when passing vec3)
window_width	Window width in pixels
window_height	Window height in pixels

Returns

Window coordinates in pixels (top-left origin, +Y down)

Inverse of normalize_coords(). Z coordinate is ignored.
