vertex shader

void main()
{
    vec4 world_pos = mtx_worldview * position;
    vec4 view_pos = mtx_view * world_pos;

    var_position = normalize(-view_pos.xyz);
    
    gl_Position = mtx_proj * view_pos;
}
fragment shader 
void main()
{
    vec4 basecolor = vec4(var_position.xyz, 1) / vec4(540, 960, 1, 1);

    out_fragColor = vec4(basecolor.rgb, 1);
}

result

i just want the view direction to be projected onto a plane :folded_hands:
