comment Normalizing a homogeneous 3d point
Looks like this person also saw corruption: piratehearts.com/blog/2010/02/13/oh-w-divide-you-so-crazy "I also discovered today that trying to do the W divide in the vertex shader is bad and wrong and bad. Interpolating (Z/W) is not the same as interpolating Z and W separately and then dividing." -- its possible OpenGL is using the W value to compute something (e.g., depth) before it normalizes the point.

comment Reflection/environment mapping
now the object looks like it has been textured with the cubemap and not looking like its 'reflecting'. Also, why can't I do the calculations in view space?

@JánosTuránszki its in eye space, so its pos-eye, but eye = 0. mvMatrix includes world matrix (it is identity)

@Raxvan, why isn't the reflection direction changing as I move around the object?
