normalize_coords_aspect() [2/2]

MAYAFLUX_API glm::vec3 MayaFlux::normalize_coords_aspect	(	double	window_x,
		double	window_y,
		uint32_t	window_width,
		uint32_t	window_height
	)

Normalize coordinates preserving aspect ratio (useful for circular/square shapes)

Parameters

window_x	X coordinate in window space
window_y	Y coordinate in window space
window_width	Window width in pixels
window_height	Window height in pixels

Returns

Aspect-corrected NDC coordinates where circles remain circular

Unlike normalize_coords(), this ensures geometric shapes maintain their proportions. The shorter dimension maps to [-1, +1], the longer dimension extends beyond.

    float aspect = aspect_ratio(window_width, window_height);

    float norm_y = 1.0F - (static_cast<float>(window_y) / static_cast<float>(window_height)) * 2.0F;
 
    if (aspect > 1.0F) {
        norm_y /= aspect;
    } else {
        norm_x *= aspect;
