# fz_shdr_get_view_dir

Description

Gets the normalized vector, representing the view direction, from the eye point, towards the current pixel. For a perspective and panoramic rendering, this direction is different for each pixel. For the other view types, this direction is the same for each pixel.
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.
