formZ SDK | 5.0 API Reference | Project | Modeling | Rendering | Shaders
Description
Gets the eye point from where the current view ray
originates. This point is not necessarily the same as
the eye point of the current view. In a perspective
view, the two are the same. In a projection view, this
point is different for each pixel rendered. This is the
inverse of the direction of the view ray, which is
constant for projection views, but different for each pixel
in a perspective view.
Note, that this function only has a meaningful use when
called from a shader's pixel function. When called from
any other place, the resulting xyz value is undefined.
