Need help:

The only change you will make is in the vertex shader. Change one line in the vertex shader so that the fragment color will be based on the world coordinates of a fragment.

Vertex Shader given:

#version $330$ core

in vec$4$ b$\_$position;

in vec$4$ b$\_$color;

$//$ what we have been calling 'transform' before is called $\text{'}$mvp$\_$transform' here

$//$ this indicates that the transform is projection times view times animation times world

uniform mat$4$ u$\_$mvp$\_$transform;

out vec$4$ s$\_$color;

out vec$4$ position;

void main$()\{$

gl$\_$Position $=$ u$\_$mvp$\_$transform $*$ b$\_$position;

s$\_$color $=$ b$\_$color;

position $=$ b$\_$position;

$\}$
