- <h2>Code Example</h2>
- <code>
- const vertices = [];
- for ( let i = 0; i < 10000; i ++ ) {
- const x = THREE.MathUtils.randFloatSpread( 2000 );
- const y = THREE.MathUtils.randFloatSpread( 2000 );
- const z = THREE.MathUtils.randFloatSpread( 2000 );
- vertices.push( x, y, z );
- }
- const geometry = new THREE.BufferGeometry();
- geometry.setAttribute( 'position', new THREE.Float32BufferAttribute( vertices, 3 ) );
- const material = new THREE.PointsMaterial( { color: 0x888888 } );
- const points = new THREE.Points( geometry, material );
- scene.add( points );

- <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.
