I am trying to prevent per-pixel shading in my glsl shader , I have searched high and wide on the web found nothing, Can someone remind me on how to do per-vertex shading in glsl.

I have dealt with this once before, this time I will write myself a note!

Do the lighting in the vertex shader, just output the colors to the fragment shader and when it gets the color, just feed it out without any further calculation.

Thanks SOL, not what I remember (to be more accurate - not what I remember what I forgot), but certainly works ;)

TBH that IS why its called per-vertex lighting and per-fragment lighting ;)

TBH I find It a little odd that by using the mix function in my per-fragment
frag shader part changes my rendering from per-vertex to per-pixel .

Seems to me that not having the per-fragment part at all would have been the solution no?

if you wanted a totally blank screen, sure, I guess so.
