Examples of org.mt4j.util.opengl.GLMaterial

org.mt4j.util.opengl.GLMaterial
Abstracts usage of OpenGL materials. Usage: instantiate a new material, set the material properties (setDiffuse(), setAmbient(), setSpecular(), setShininess()), call material.apply() in your render function to set the OpenGL current material properties.

    MTLight.enableLightningAndAmbient(mtApplication, 150, 150, 150, 255);
    //Create a light source //I think GL_LIGHT0 is used by processing!
    MTLight light = new MTLight(mtApplication, GL.GL_LIGHT3, new Vector3D(0,-300,0));
    
    //Set up a material to react to the light
    GLMaterial material = new GLMaterial(Tools3D.getGL(mtApplication));
    material.setAmbient(new float[]{ .5f, .5f, .5f, 1f });
    material.setDiffuse(new float[]{ .8f, .8f, .8f, 1f } );
    material.setEmission(new float[]{ .0f, .0f, .0f, 1f });
    material.setSpecular(new float[]{ 0.9f, 0.9f, 0.9f, 1f });  // almost white: very reflective
    material.setShininess(110);// 0=no shine,  127=max shine
    
    //Group used to move to the screen center and to put the mesh group in
    MTComponent group1 = new MTComponent(mtApplication);
    
    //Create a group and set the light for the whole mesh group ->better for performance than setting light to more comps
