Chapter 4 & 5: Confusing wording and inconsistencies

[switchfl1p]

Hello,

I'll refer to the paragraphs I'm having issues with by their number after a specific heading. These are for this specific page:
https://paroj.github.io/gltut/Positioning/Tut04%20Perspective%20Projection.html

• Paragraph 7 under Camera Perspective

"the eye's location relative to the plane of projection is (0, 0, -1)"

If the perspective plane is at (0,0,-1) and pointing down the -Z axis, with the eye fixed at (0, 0, 0) the eyes location relative to the plane of projection is (0,0,1). Not sure what the original intent was here, maybe the reverse? "the plane of projection's location relative to the eye is (0, 0, -1)"

• Paragraph 7 under Drawing In Perspective

"The eye is fixed at (0, 0, -1)"

Added this just for the sake of completeness since it's been explained in another issue but it's still incorrect on the current build. It should be "the plane is fixed at (0, 0, -1)"

In chapter 5 the 1st issue makes a return https://paroj.github.io/gltut/Positioning/Tut05%20Boundaries%20and%20Clipping.html

• Paragraph 1 under Equation 5.1. Perspective Computation

"Ez is the Z-position of the eye relative to the plane (assumed to be -1)"

Should be the reverse if the above assumption is correct, so the plane relative to the eye
