- <p class="desc">
- A material for non-shiny surfaces, without specular highlights.<br /><br />
- The material uses a non-physically based [link:https://en.wikipedia.org/wiki/Lambertian_reflectance Lambertian]
- model for calculating reflectance. This can simulate some surfaces (such as untreated wood or stone) well,
- but cannot simulate shiny surfaces with specular highlights (such as varnished wood).<br /><br />
- Shading is calculated using a [link:https://en.wikipedia.org/wiki/Gouraud_shading Gouraud] shading model.
- This calculates shading per vertex (i.e. in the [link:https://en.wikipedia.org/wiki/Shader#Vertex_shaders vertex shader])
- and interpolates the results over the polygon's faces.<br /><br />
- Due to the simplicity of the reflectance and illumination models, performance will be greater
- when using this material over the [page:MeshPhongMaterial], [page:MeshStandardMaterial] or [page:MeshPhysicalMaterial],
- at the cost of some graphical accuracy.

- <h2>Constructor</h2>
- <h3>[name]( [param:Object parameters] )</h3>
- <p>
- [page:Object parameters] - (optional) an object with one or more properties defining the material's appearance.
- Any property of the material (including any property inherited from [page:Material]) can be passed in here.<br /><br />
- The exception is the property [page:Hexadecimal color], which can be passed in as a hexadecimal
- string and is *0xffffff* (white) by default. [page:Color.set]( color ) is called internally.
- </p>
- <h2>Properties</h2>
- <p>See the base [page:Material] class for common properties.</p>
- <h3>[property:Texture alphaMap]</h3>
- <p>The alpha map is a grayscale texture that controls the opacity across the surface
- (black: fully transparent; white: fully opaque). Default is null.<br /><br />
- Only the color of the texture is used, ignoring the alpha channel if one exists.
- For RGB and RGBA textures, the [page:WebGLRenderer WebGL] renderer will use the
- green channel when sampling this texture due to the extra bit of precision provided
- for green in DXT-compressed and uncompressed RGB 565 formats. Luminance-only and
- luminance/alpha textures will also still work as expected.
- </p>
- <h3>[property:Texture aoMap]</h3>
- <p>The red channel of this texture is used as the ambient occlusion map. Default is null.
- The aoMap requires a second set of UVs.</p>
- <h3>[property:Float aoMapIntensity]</h3>
- <p>Intensity of the ambient occlusion effect. Default is 1. Zero is no occlusion effect.</p>
- <h3>[property:Color color]</h3>
- <p>[page:Color] of the material, by default set to white (0xffffff).</p>
- <h3>[property:Integer combine]</h3>
- <p>
- How to combine the result of the surface's color with the environment map, if any.<br /><br />
- Options are [page:Materials THREE.Multiply] (default), [page:Materials THREE.MixOperation],
- [page:Materials THREE.AddOperation]. If mix is chosen, the [page:.reflectivity] is used to
- blend between the two colors.
- </p>
- <h3>[property:Color emissive]</h3>
- <p>
- Emissive (light) color of the material, essentially a solid color unaffected by other lighting.
- Default is black.
- </p>
- <h3>[property:Texture emissiveMap]</h3>
- <p>
- Set emissive (glow) map. Default is null. The emissive map color is modulated by
- the emissive color and the emissive intensity. If you have an emissive map, be sure to
- set the emissive color to something other than black.
- </p>
- <h3>[property:Float emissiveIntensity]</h3>
- <p>Intensity of the emissive light. Modulates the emissive color. Default is 1.</p>
- <h3>[property:Texture envMap]</h3>
- <p>The environment map. Default is null.</p>
- <h3>[property:Texture lightMap]</h3>
- <p>The light map. Default is null. The lightMap requires a second set of UVs.</p>
- <h3>[property:Float lightMapIntensity]</h3>
- <p>Intensity of the baked light. Default is 1.</p>
- <h3>[property:Texture map]</h3>
- <p>The color map. Default is null.</p>
- <h3>[property:Boolean morphNormals]</h3>
- <p>
- Defines whether the material uses morphNormals. Set as true to pass morphNormal
- attributes from the geometry to the shader. Default is *false*.
- </p>
- <h3>[property:Boolean morphTargets]</h3>
- <p>Define whether the material uses morphTargets. Default is false.</p>
- <h3>[property:Float reflectivity]</h3>
- <p>How much the environment map affects the surface; also see [page:.combine].</p>
- <h3>[property:Float refractionRatio]</h3>
- <p>
- The index of refraction (IOR) of air (approximately 1) divided by the index of refraction of the material.
- It is used with environment mapping modes [page:Textures THREE.CubeRefractionMapping] and [page:Textures THREE.EquirectangularRefractionMapping].
- The refraction ratio should not exceed 1. Default is *0.98*.
- </p>
- <h3>[property:Boolean skinning]</h3>
- <p>Define whether the material uses skinning. Default is false.</p>
- <h3>[property:Texture specularMap]</h3>
- <p>Specular map used by the material. Default is null.</p>
- <h3>[property:Boolean wireframe]</h3>
- <p>Render geometry as wireframe. Default is *false* (i.e. render as flat polygons).</p>
- <h3>[property:String wireframeLinecap]</h3>
- <p>
- Define appearance of line ends. Possible values are "butt", "round" and "square". Default is 'round'.<br /><br />
- This corresponds to the [link:https://developer.mozilla.org/en/docs/Web/API/CanvasRenderingContext2D/lineCap 2D Canvas lineCap]
- property and it is ignored by the [page:WebGLRenderer WebGL] renderer.
- </p>
- <h3>[property:String wireframeLinejoin]</h3>
- <p>
- Define appearance of line joints. Possible values are "round", "bevel" and "miter". Default is 'round'.<br /><br />
- This corresponds to the [link:https://developer.mozilla.org/en/docs/Web/API/CanvasRenderingContext2D/lineJoin 2D Canvas lineJoin]
- property and it is ignored by the [page:WebGLRenderer WebGL] renderer.
- </p>
- <h3>[property:Float wireframeLinewidth]</h3>
- <p>Controls wireframe thickness. Default is 1.<br /><br />
- Due to limitations of the [link:https://www.khronos.org/registry/OpenGL/specs/gl/glspec46.core.pdf OpenGL Core Profile]
- with the [page:WebGLRenderer WebGL] renderer on most platforms linewidth will
- always be 1 regardless of the set value.
