<h1>Texture Constants</h1>

|
<h2>Mapping Modes</h2>
|
||
|
|
<code>
|
||
|
|
THREE.UVMapping
|
||
|
|
THREE.CubeReflectionMapping
|
||
|
|
THREE.CubeRefractionMapping
|
||
|
|
THREE.EquirectangularReflectionMapping
|
||
|
|
THREE.EquirectangularRefractionMapping
|
||
|
|
THREE.CubeUVReflectionMapping
|
||
|
|
</code>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
These define the texture's mapping mode.<br />
|
||
|
|
[page:Constant UVMapping] is the default, and maps the texture using the mesh's UV coordinates.<br /><br />
|
||
|
|
|
||
|
|
The rest define environment mapping types.<br /><br />
|
||
|
|
|
||
|
|
[page:Constant CubeReflectionMapping] and [page:Constant CubeRefractionMapping] are for
|
||
|
|
use with a [page:CubeTexture CubeTexture], which is made up of six textures, one for each face of the cube.
|
||
|
|
[page:Constant CubeReflectionMapping] is the default for a [page:CubeTexture CubeTexture]. <br /><br />
|
||
|
|
|
||
|
|
[page:Constant EquirectangularReflectionMapping] and [page:Constant EquirectangularRefractionMapping]
|
||
|
|
are for use with an equirectangular environment map. Also called a lat-long map, an equirectangular
|
||
|
|
texture represents a 360-degree view along the horizontal centerline, and a 180-degree view along the
|
||
|
|
vertical axis, with the top and bottom edges of the image corresponding to the north and south poles
|
||
|
|
of a mapped sphere.<br /><br />
|
||
|
|
|
||
|
|
See the [example:webgl_materials_envmaps materials / envmaps] example.

<h2>Wrapping Modes</h2>
|
||
|
|
<code>
|
||
|
|
THREE.RepeatWrapping
|
||
|
|
THREE.ClampToEdgeWrapping
|
||
|
|
THREE.MirroredRepeatWrapping
|
||
|
|
</code>
|
||
|
|
<p>
|
||
|
|
These define the texture's [page:Texture.wrapS wrapS] and [page:Texture.wrapT wrapT] properties,
|
||
|
|
which define horizontal and vertical texture wrapping.<br /><br />
|
||
|
|
|
||
|
|
With [page:constant RepeatWrapping] the texture will simply repeat to infinity.<br /><br />
|
||
|
|
|
||
|
|
[page:constant ClampToEdgeWrapping] is the default.
|
||
|
|
The last pixel of the texture stretches to the edge of the mesh.<br /><br />
|
||
|
|
|
||
|
|
With [page:constant MirroredRepeatWrapping] the texture will repeats to infinity, mirroring on each repeat.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h2>Magnification Filters</h2>
|
||
|
|
<code>
|
||
|
|
THREE.NearestFilter
|
||
|
|
THREE.LinearFilter
|
||
|
|
</code>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
For use with a texture's [page:Texture.magFilter magFilter] property,
|
||
|
|
these define the texture magnification function to be used when the pixel being textured maps to an
|
||
|
|
area less than or equal to one texture element (texel).<br /><br />
|
||
|
|
|
||
|
|
[page:constant NearestFilter] returns the value of the texture element that is nearest
|
||
|
|
(in Manhattan distance) to the specified texture coordinates.<br /><br />
|
||
|
|
|
||
|
|
[page:constant LinearFilter] is the default and returns the weighted average
|
||
|
|
of the four texture elements that are closest to the specified texture coordinates,
|
||
|
|
and can include items wrapped or repeated from other parts of a texture,
|
||
|
|
depending on the values of [page:Texture.wrapS wrapS] and [page:Texture.wrapT wrapT], and on the exact mapping.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h2>Minification Filters</h2>
|
||
|
|

|
||
|

|
||
|
|
THREE.LinearFilter
|
||
|
|
THREE.LinearMipmapNearestFilter
|
||
|
|
THREE.LinearMipmapLinearFilter
|
||
|
|
</code>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
For use with a texture's [page:Texture.minFilter minFilter] property, these define
|
||
|
|
the texture minifying function that is used whenever the pixel being textured maps
|
||
|
|
to an area greater than one texture element (texel).<br /><br />
|
||
|
|
|
||
|
|
In addition to [page:constant NearestFilter] and [page:constant LinearFilter],
|
||
|
|
the following four functions can be used for minification:<br /><br />
|
||
|
|
|
||
|
|
[page:constant NearestMipmapNearestFilter] chooses the mipmap that most closely
|
||
|
|
matches the size of the pixel being textured
|
||
|
|
and uses the [page:constant NearestFilter] criterion (the texel nearest to the
|
||
|
|
center of the pixel) to produce a texture value.<br /><br />
|
||
|
|
|
||
|
|
[page:constant NearestMipmapLinearFilter] chooses the two mipmaps that most closely
|
||
|
|
match the size of the pixel being textured and uses the [page:constant NearestFilter] criterion to produce
|
||
|
|
a texture value from each mipmap. The final texture value is a weighted average of those two values.<br /><br />
|
||
|
|
|
||
|
|
[page:constant LinearMipmapNearestFilter] chooses the mipmap that most closely matches
|
||
|
|
the size of the pixel being textured and uses the [page:constant LinearFilter] criterion
|
||
|
|
(a weighted average of the four texels that are closest to the center of the pixel)
|
||
|
|
to produce a texture value.<br /><br />
|
||
|
|
|
||
|
|
[page:constant LinearMipmapLinearFilter] is the default and chooses the two mipmaps
|
||
|
|
that most closely match the size of the pixel being textured and uses the [page:constant LinearFilter] criterion
|
||
|
|
to produce a texture value from each mipmap. The final texture value is a weighted average of those two values.<br /><br />
|
||
|
|
|
||

|
||
|
|
|
||
|
|

|
||
|
|
</p>
|

|
|
|

|
||
|
|
</code>
|
||
|
|
<p>
|
||
|
|
For use with a texture's [page:Texture.format format] property, these define
|
||
|
|
how elements of a 2d texture, or `texels`, are read by shaders.<br /><br />
|
||
|
|
|
||
|
|
[page:constant AlphaFormat] discards the red, green and blue components and reads just the alpha component.<br /><br />
|
||
|
|
|
||
|
|
[page:constant RedFormat] discards the green and blue components and reads just the red component.
|
||
|
|
(can only be used with a WebGL 2 rendering context).
|
||
|
|
<br /><br />
|
||
|
|
|
||
|
|
[page:constant RedIntegerFormat] discards the green and blue components and reads just the red component.
|
||
|
|
The texels are read as integers instead of floating point.
|
||
|
|
(can only be used with a WebGL 2 rendering context).
|
||
|
|
<br /><br />
|
||
|
|
|
||
|
|
[page:constant RGFormat] discards the alpha, and blue components and reads the red, and green components.
|
||
|
|
(can only be used with a WebGL 2 rendering context).
|
||
|
|
<br /><br />
|
||
|
|
|
||
|
|
[page:constant RGIntegerFormat] discards the alpha, and blue components and reads the red, and green components.
|
||
|
|
The texels are read as integers instead of floating point.
|
||
|
|
(can only be used with a WebGL 2 rendering context).
|
||
|
|
<br /><br />
|
||
|
|
|
||
|
|
[page:constant RGBAFormat] is the default and reads the red, green, blue and alpha components.<br /><br />
|
||
|
|
|
||
|
|
[page:constant RGBAIntegerFormat] is the default and reads the red, green, blue and alpha components.
|
||
|
|
The texels are read as integers instead of floating point.
|
||
|
|
(can only be used with a WebGL 2 rendering context).
|
||
|
|
<br /><br />
|
||
|
|
|
||
|
|
[page:constant LuminanceFormat] reads each element as a single luminance component.
|
||
|
|
This is then converted to a floating point, clamped to the range [0,1], and then assembled
|
||
|
|
into an RGBA element by placing the luminance value in the red, green and blue channels,
|
||
|
|
and attaching 1.0 to the alpha channel.<br /><br />
|
||
|
|
|
||
|
|
[page:constant LuminanceAlphaFormat] reads each element as a luminance/alpha double.
|
||
|
|
The same process occurs as for the [page:constant LuminanceFormat], except that the
|
||
|
|
alpha channel may have values other than `1.0`.<br /><br />
|
||
|
|
|
||
|
|
[page:constant DepthFormat] reads each element as a single depth value, converts it to floating point, and clamps to the range [0,1].
|
||
|
|
This is the default for [page:DepthTexture DepthTexture].<br /><br />
|
||
|
|
|
||
|
|
[page:constant DepthStencilFormat] reads each element is a pair of depth and stencil values.
|
||
|
|
The depth component of the pair is interpreted as in [page:constant DepthFormat].
|
||
|
|
The stencil component is interpreted based on the depth + stencil internal format.
|
||
|
|
<br /><br />
|
||
|
|
|
||
|
|
Note that the texture must have the correct [page:Texture.type type] set, as described above.

Heads up: changing the internal format of a texture will only affect the
|
||
|
|
texture when using a WebGL 2 rendering context.<br /><br />
|
||
|
|
|
||
|
|
For use with a texture's [page:Texture.internalFormat internalFormat] property,
|
||
|
|
these define how elements of a texture, or `texels`, are stored on the GPU.<br /><br />

For use with a Texture's [page:Texture.encoding encoding] property.<br /><br />
|
||
|
|
|
||
|
|
If the encoding type is changed after the texture has already been used by a material,
|

|
|
you will need to set [page:Material.needsUpdate Material.needsUpdate] to `true` to make the material recompile.<br /><br />
|

|
[page:constant LinearEncoding] is the default.
