I am looking at the Textured Box demo https://cvs.khronos.org/svn/repos/regis ... itBox.html listed on http://khronos.org/webgl/wiki/Demo_Repository

I'd like to add a white square without texture to this demo so it will have 1 textured object (the original demo) and 1 object without texture.

The demo has the following code to texture the cube
Code :
<script id="fshader" type="x-shader/x-fragment">
#ifdef GL_ES
    precision mediump float;
#endif
 
    uniform sampler2D sampler2d;
 
    varying float v_Dot;
    varying vec2 v_texCoord;
 
    void main()
    {
        vec2 texCoord = vec2(v_texCoord.s, 1.0 - v_texCoord.t);
        vec4 color = texture2D(sampler2d, texCoord);
        color += vec4(0.1, 0.1, 0.1, 1);
        gl_FragColor = vec4(color.xyz * v_Dot, color.a);
    }
</script>

What do I need to do to draw the white square without texture?

Thanks in advance for your help.
