<p class="desc">
|

|

[name] is defined by a MatCap (or Lit Sphere) texture, which encodes the material color and shading.<br/><br/>
|
||
|
|
[name] does not respond to lights since the matcap image file encodes baked lighting.
|
||
|
|
It will cast a shadow onto an object that receives shadows (and shadow clipping works), but it will not self-shadow or receive shadows.

<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 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:Boolean flatShading]</h3>
|
||
|
|
<p>
|
||
|
|
Define whether the material is rendered with flat shading. Default is false.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean fog]</h3>
|
||
|
|
<p>Whether the material is affected by fog. Default is `true`.</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 matcap]</h3>
|
||
|
|
<p>The matcap map. Default is null.</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).
|
||
|
