										<p>

										[page:HTMLElement canvas] -- The HTML canvas element from which to load the texture. <br />
							 | 
						||

								 | 
							
								
							 | 
						||
| 
								 | 
							
										[page:Constant mapping] --  How the image is applied to the object. An object type of [page:Textures THREE.UVMapping].
							 |

								 | 
							
										See [page:Textures mapping constants] for other choices.<br />
							 |

										[page:Constant wrapS] -- The default is [page:Textures THREE.ClampToEdgeWrapping].

										See [page:Textures wrap mode constants] for other choices.<br />

							 | 
						||
|

							 | 
						||
| 
								 | 
							
										[page:Constant magFilter] -- How the texture is sampled when a texel covers more than one pixel.
							 | 
						||
| 
								 | 
							
										The default is [page:Textures THREE.LinearFilter]. See [page:Textures magnification filter constants] for other choices.<br />
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
										[page:Constant minFilter] -- How the texture is sampled when a texel covers less than one pixel.
							 | 
						||
| 
								 | 
							
										 The default is [page:Textures THREE.LinearMipmapLinearFilter]. See [page:Textures minification filter constants] for other choices.<br />
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								    [page:Constant format] -- The format used in the texture.
							 | 
						||
| 
								 | 
							
								     See [page:Textures format constants] for other choices.<br />
							 | 
						||
| 
								 | 
							
								
							 |

								    [page:Constant type] -- Default is [page:Textures THREE.UnsignedByteType].

| 
								 | 
							
										[page:Number anisotropy] -- The number of samples taken along the axis through the pixel that has the highest density of texels.
							 | 
						||
| 
								 | 
							
										By default, this value is 1. A higher value gives a less blurry result than a basic mipmap, at the cost of more texture samples being used.
							 | 
						||
| 
								 | 
							
										Use [page:WebGLrenderer.getMaxAnisotropy renderer.getMaxAnisotropy]() to find the maximum valid anisotropy value for the GPU; this value is usually a power of 2.<br /><br />
