Line 23:

In both the proposed approaches there are two little problems which can be trivially solved and comes from the different conventions used by eye space and texture space.

Defining properties of those spaces is beyond the scope of this article but it's well known that textures should usually be addressed in the range [0..1[] while eye space coordinates are addressed in the range [-1..1].

According to the used texture wrap mode various artifacts may occur but it's obvious a shift and scale operation is definitely necessary to get the expected result.
