H3DU.TextureInfo

H3DU.TextureInfo([params])

Specifies information about a texture, which can serve as image data applied to the surface of a shape, or even a 2-dimensional array of pixels used for some other purpose, such as a depth map, a height map, a bump map, a specular map, and so on.

By default, texture coordinates go from (0,0) at the lower-left corner to (1,1) at the upper-right corner (because the "topDown" property is false by default).

For best results, any textures to be used in WebGL should have width and height each equal to a power of 2, such as 2, 4, 8, 16, and 32.

Parameters

params (Type: Object) (optional)
An object as described in H3DU.TextureInfo.setParams.

Methods

copyFrom
Copies the parameters from another texture information object to this object.
setParams
Sets parameters for this texture information object.

H3DU.TextureInfo#copyFrom([other])

Copies the parameters from another texture information object to this object.

Parameters

other (Type: H3DU.TextureInfo) (optional)
Texture information object to copy.

Return Value

This object. (Type: H3DU.TextureInfo)

H3DU.TextureInfo#setParams(params)

Sets parameters for this texture information object.

Parameters

params (Type: Object)
An object whose keys have the possibilities given later, and whose values are those allowed for each key.
- uri - URI (Internet address) of the texture's data.
- format - Specifies the kind of data stored in each pixel of the texture. Can be 6406, 6407, 6408 (RGBA), 6409, 6410.
- internalFormat - Specifies the format of the texture. Can be one of the values for "format".
- target - Specifies the texture target. Can be 3553 (TEXTURE_2D).
- type - Specifies the data type used to encode each pixel component in the texture. Can be 5121, 33635, 32819, 32820.
- magFilter - Specifies the filter to use when enlarging the texture. Can be 9728 (NEAREST) or 9729 (LINEAR).
- minFilter - Specifies the filter to use when shrinking the texture. Can be one of the values for "magFilter" or 9984, 9985, 9986 (NEAREST_MIPMAP_LINEAR), 9987.
- wrapS - Specifies the wrapping mode in the S (horizontal) axis. Can be 10497 (REPEAT), 33071, 33648.
- wrapT -Specifies the wrapping mode in the T (horizontal) axis. Can be one of the values for "wrapS".
- topDown - If true, the image's data will be stored starting from the top row and proceeding downwards.
Any or all of these keys can exist in the parameters object. If a value is null or undefined, it is ignored unless otherwise noted.

Return Value

This object. (Type: H3DU.TextureInfo)
