<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. Range is 0-1, where `0`
|
|
disables ambient occlusion. Where intensity is `1` and the [page:.aoMap]
|
|
red channel is also `1`, ambient light is fully occluded on a surface.
|
|
Default is `1`.
|
|
</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.MultiplyOperation] (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:Texture envMap]</h3>
|
|
<p>The environment map. Default is null.</p>
|
|
|
|
<h3>[property:Euler envMapRotation]</h3>
|
|
<p>
|
|
The rotation of the environment map in radians. Default is `(0,0,0)`.
|
|
</p>
|
|
|
|
<h3>[property:Boolean fog]</h3>
|
|
<p>Whether the material is affected by fog. Default is `true`.</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. May optionally include an alpha channel, typically combined
|
|
with [page:Material.transparent .transparent] or [page:Material.alphaTest .alphaTest]. Default is null.
|
|
</p>
|
|
|
|
<h3>[property:Float reflectivity]</h3>
|
|
<p>
|
|
How much the environment map affects the surface; also see
|
|
[page:.combine]. The default value is `1` and the valid range is between `0`
|
|
(no reflections) and `1` (full reflections).
|
|
</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: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.
