<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:Color color]</h3>
|
||
|
|
<p>[page:Color] of the material, by default set to white (0xffffff).</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean fog]</h3>
|
||
|
|
<p>Whether the material is affected by fog. Default is `true`.</p>
|
||
|
|
|
||
|
|
<h3>[property:Texture map]</h3>
|
||
|
|
<p>
|
||
|
|
Sets the color of the points using data from a [page:Texture].
|
||
|
|
May optionally include an alpha channel, typically combined with
|
||
|
|
[page:Material.transparent .transparent] or [page:Material.alphaTest .alphaTest].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Number size]</h3>
|
||
|
|
<p>Defines the size of the points in pixels. Default is 1.0.<br/>
|
||
|
|
Will be capped if it exceeds the hardware dependent parameter [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/getParameter gl.ALIASED_POINT_SIZE_RANGE].</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean sizeAttenuation]</h3>
|
||
|
|
<p>Specify whether points' size is attenuated by the camera depth. (Perspective camera only.) Default is true.</p>

||
