<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:Color color]</h3>
<p>[page:Color] of the material, by default set to white (0xffffff).</p>
<h3>[property:Boolean isPointsMaterial]</h3>
<p>
Used to check whether this or derived classes are points materials. Default is *true*.<br /><br />
You should not change this, as it used internally for optimisation.
</p>
<h3>[property:Texture map]</h3>
<p>Sets the color of the points using data from a [page:Texture].</p>
<h3>[property:Boolean morphTargets]</h3>
<p>Define whether the material uses morphTargets. Default is false.</p>
<h3>[property:Number size]</h3>
<p>Sets the size of the points. Default is 1.0.</p>
<h3>[property:Boolean sizeAttenuation]</h3>
<p>Specify whether points' size is attenuated by the camera depth. (Perspective camera only.) Default is true.</p>
