CreateRayFromViewportPoint()

BlamRay Blam::RenderingBGFX::CreateRayFromViewportPoint	(	int	screen_x,
		int	screen_y
	)

Constructs a world-space ray from a screen-space cursor position.

Unprojects two points (at the near and far clip planes) from screen space through the inverse of the combined view-projection matrix to produce a ray origin and normalized direction in world space.

The near clip Z value is chosen based on bgfx's reported depth range: 0.0 for D3D/Vulkan (depth in [0,1]) and -1.0 for OpenGL (depth in [-1,1]).

Parameters

screen_x	Screen X position in pixels.
screen_y	Screen Y position in pixels.

Returns

A BlamRay with world-space origin and normalized direction.
