<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:Texture bumpMap]</h3>
|
||
|
|
<p>
|
||
|
|
The texture to create a bump map. The black and white values map to the perceived depth in relation to the lights.
|
||
|
|
Bump doesn't actually affect the geometry of the object, only the lighting. If a normal map is defined this will
|
||
|
|
be ignored.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Float bumpScale]</h3>
|
||
|
|
<p>How much the bump map affects the material. Typical ranges are 0-1. Default is 1.</p>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[property:Color color]</h3>
|
||
|
|
<p>[page:Color] of the material, by default set to white (0xffffff).</p>
|
||
|
|
|
||
|
|
<h3>[property:Texture displacementMap]</h3>
|
||
|
|
<p>
|
||
|
|
The displacement map affects the position of the mesh's vertices. Unlike other maps
|
||
|
|
which only affect the light and shade of the material the displaced vertices can cast shadows,
|
||
|
|
block other objects, and otherwise act as real geometry. The displacement texture is
|
||
|
|
an image where the value of each pixel (white being the highest) is mapped against,
|
||
|
|
and repositions, the vertices of the mesh.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Float displacementScale]</h3>
|
||
|
|
<p>
|
||
|
|
How much the displacement map affects the mesh (where black is no displacement,
|
||
|
|
and white is maximum displacement). Without a displacement map set, this value is not applied.
|
||
|
|
Default is 1.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Float displacementBias]</h3>
|
||
|
|
<p>
|
||
|
|
The offset of the displacement map's values on the mesh's vertices.
|
||
|
|
Without a displacement map set, this value is not applied. Default is 0.
|
||
|
|
</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:Boolean fog]</h3>
|
||
|
|
<p>材质是否受雾影响。默认为*true*。</p>
|
||
|
|
|
||
|
|
<h3>[property:Texture gradientMap]</h3>
|
||
|
|
<p>Gradient map for toon shading. It's required to set [page:Texture.minFilter] and [page:Texture.magFilter] to
|
||
|
|
[page:Textures THREE.NearestFilter] when using this type of texture. 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. May optionally include an alpha channel, typically combined with
|
||
|
|
[page:Material.transparent .transparent] or [page:Material.alphaTest .alphaTest]. Default is null.
|
||
|
|
The texture map color is modulated by the diffuse [page:.color].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Texture normalMap]</h3>
|
||
|
|
<p>
|
||
|
|
The texture to create a normal map. The RGB values affect the surface normal for each pixel fragment and change
|
||
|
|
the way the color is lit. Normal maps do not change the actual shape of the surface, only the lighting.
|
||
|
|
In case the material has a normal map authored using the left handed convention, the y component of normalScale
|
||
|
|
should be negated to compensate for the different handedness.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Integer normalMapType]</h3>
|
||
|
|
<p>
|
||
|
|
The type of normal map.<br /><br />
|
||
|
|
|
||
|
|
Options are [page:constant THREE.TangentSpaceNormalMap] (default), and [page:constant THREE.ObjectSpaceNormalMap].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Vector2 normalScale]</h3>
|
||
|
|
<p>
|
||
|
|
How much the normal map affects the material. Typical ranges are 0-1.
|
||
|
|
Default is a [page:Vector2] set to (1,1).
|
||
|
|
</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.
