Overview

MetallicMaterial is usually used for conductive materials, such as metal.
SpecularMaterial is usually used for insulators, such as wood, ceramics and plastic.
PhongMaterial is usually used for non-realistic objects.

Usage

In the example below we'll create the yellow fire hydrant shown in the example screen shots above. Our hydrant Mesh has:

a OBJGeometry which loads the fire hydrant mesh from an .OBJ file,
a MetallicMaterial with Textures providing diffuse, metallic, roughness, occlusion and normal maps.

We'll also provide its Scene's Lights with DirLights, plus CubeTextures for light and reflection maps.

Note that in this example we're providing separate Textures for the metallic and roughness channels, which allows us a little creative flexibility. Then, in the next example further down, we'll combine those channels within the same Texture for efficiency.

var hydrant = new xeogl.Mesh({

   geometry: new xeogl.OBJGeometry({
       src: "models/obj/FireHydrantMesh.obj"
   }),

   material: new xeogl.MetallicMaterial({

       // Channels with default values, just to show them

       baseColor: [1.0, 1.0, 1.0],
       metallic: 1.0,
       roughness: 1.0,
       emissive: [0.0, 0.0, 0.0],
       alpha: 1.0,

       // Textures to multiply by some of the channels

       baseColorMap : new xeogl.Texture({  // Multiplies by baseColor
           src: "textures/diffuse/fire_hydrant_Base_Color.png"
       }),

       metallicMap : new xeogl.Texture({   // R component multiplies by metallic
           src: "textures/metallic/fire_hydrant_Metallic.png"
       }),

       roughnessMap : new xeogl.Texture({  // R component multiplies by roughness
           src: "textures/roughness/fire_hydrant_Roughness.png"
       }),

       occlusionMap : new xeogl.Texture({  // Multiplies by fragment alpha
           src: "textures/occlusion/fire_hydrant_Mixed_AO.png"
       }),

       normalMap : new xeogl.Texture({
           src: "textures/normal/fire_hydrant_Normal_OpenGL.png"
       })
   })
});

var scene = hydrant.scene;

scene.lights.lights = [
new xeogl.DirLight({
        dir: [0.8, -0.6, -0.8],
        color: [0.8, 0.8, 0.8],
        space: "view"
    }),
new xeogl.DirLight({
        dir: [-0.8, -0.4, -0.4],
        color: [0.4, 0.4, 0.5],
        space: "view"
    }),
new xeogl.DirLight({
        dir: [0.2, -0.8, 0.8],
        color: [0.8, 0.8, 0.8],
        space: "view"
    }
];

scene.lights.lightMap = new xeogl.CubeTexture({
    src: [
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_PX.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_NX.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_PY.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_NY.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_PZ.png",
        "textures/light/Uffizi_Gallery/Uffizi_Gallery_Irradiance_NZ.png"
    ]
});

scene.lights.reflectionMap = new xeogl.CubeTexture({
    src: [
        "textures/reflect/Uffizi_Gallery/Uffizi_Gallery_Radiance_PX.png",
        "textures/reflect/Uffizi_Gallery/Uffizi_Gallery_Radiance_NX.png",
        "textures/reflect/Uffizi_Gallery/Uffizi_Gallery_Radiance_PY.png",
        "textures/reflect/Uffizi_Gallery/Uffizi_Gallery_Radiance_NY.png",
        "textures/reflect/Uffizi_Gallery/Uffizi_Gallery_Radiance_PZ.png",
        "textures/reflect/Uffizi_Gallery/Uffizi_Gallery_Radiance_NZ.png"
    ]
});

Combining channels within the same textures

In the previous example we provided separate Textures for the metallic and roughness channels, but we can combine those channels into the same Texture to reduce download time, memory footprint and rendering time (and also for glTF compatibility).

Here's our MetallicMaterial again with those channels combined in the metallicRoughnessMap Texture, where the R component multiplies by metallic and G multiplies by roughness.

hydrant.material = new xeogl.MetallicMaterial({

   baseColor: [1,1,1], // Default value
   metallic: 1.0,      // Default value
   roughness: 1.0,     // Default value

   baseColorMap : new xeogl.Texture({
       src: "textures/diffuse/fire_hydrant_Base_Color.png"
   }),
   metallicRoughnessMap : new xeogl.Texture({
       src: "textures/metallicRoughness/fire_hydrant_MetallicRoughness.png"
   }),
   occlusionMap : new xeogl.Texture({
       src: "textures/occlusion/fire_hydrant_Mixed_AO.png"
   }),
   normalMap : new xeogl.Texture({
       src: "textures/normal/fire_hydrant_Normal_OpenGL.png"
   })
});

Although not shown in this example, we can also texture alpha with the A component of baseColorMap's Texture, if required.

Transparency

Alpha Blending

Let's make our hydrant transparent.

We'll update its MetallicMaterial's alpha and alphaMode, causing it to blend 50% with the background:

hydrant.material.alpha = 0.5;
hydrant.material.alphaMode = "blend";

Alpha Masking

Let's apply an alpha mask to our hydrant.

We'll give its MetallicMaterial an alphaMap and configure alpha, alphaMode, and alphaCutoff to treat it as an alpha mask:

hydrant.material.alphaMap = new xeogl.Texture({
       src: "textures/diffuse/crossGridColorMap.jpg"
   });

hydrant.material.alpha = 1.0;
hydrant.material.alphaMode = "mask";
hydrant.material.alphaCutoff = 0.2;

A value greater than 1.0 will render the entire material as fully transparent. This value is ignored for other modes.

Alpha is the combined result of the alpha and alphaMap properties.

Default: 0.5

`alphaMap`

"opaque" - The alpha value is ignored and the rendered output is fully opaque.
"mask" - The rendered output is either fully opaque or fully transparent depending on the alpha and alphaCutoff.
