WebGLRenderingContext: texParameter[fi]() method - Web APIs

Syntax

js

texParameterf(target, pname, param)
texParameteri(target, pname, param)

Parameters

target

A GLenum specifying the binding point (target). Possible values:

gl.TEXTURE_2D: A two-dimensional texture.
gl.TEXTURE_CUBE_MAP: A cube-mapped texture.

When using a WebGL 2 context, the following values are available additionally:

gl.TEXTURE_3D: A three-dimensional texture.
gl.TEXTURE_2D_ARRAY: A two-dimensional array texture.

param

The param parameter is a GLfloat or GLint specifying the value for the specified parameter

pname

The pname parameter is a GLenum specifying the texture parameter to set.

`pname`	Description	`param`
Available in WebGL 1
`gl.TEXTURE_MAG_FILTER`	Texture magnification filter	`gl.LINEAR` (default value), `gl.NEAREST`.
`gl.TEXTURE_MIN_FILTER`	Texture minification filter	`gl.LINEAR`, `gl.NEAREST`, `gl.NEAREST_MIPMAP_NEAREST`, `gl.LINEAR_MIPMAP_NEAREST`, `gl.NEAREST_MIPMAP_LINEAR` (default value), `gl.LINEAR_MIPMAP_LINEAR`.
`gl.TEXTURE_WRAP_S`	Wrapping function for texture coordinate `s`	`gl.REPEAT` (default value), `gl.CLAMP_TO_EDGE`, `gl.MIRRORED_REPEAT`.
`gl.TEXTURE_WRAP_T`	Wrapping function for texture coordinate `t`	`gl.REPEAT` (default value), `gl.CLAMP_TO_EDGE`, `gl.MIRRORED_REPEAT`.
Additionally available when using the `EXT_texture_filter_anisotropic` extension
`ext.TEXTURE_MAX_ANISOTROPY_EXT`	Maximum anisotropy for a texture	A `GLfloat` value.
Additionally available when using a WebGL 2 context
`gl.TEXTURE_BASE_LEVEL`	Texture mipmap level	Any int values.
`gl.TEXTURE_COMPARE_FUNC`	Texture Comparison function	`gl.LEQUAL` (default value), `gl.GEQUAL`, `gl.LESS`, `gl.GREATER`, `gl.EQUAL`, `gl.NOTEQUAL`, `gl.ALWAYS`, `gl.NEVER`.
`gl.TEXTURE_COMPARE_MODE`	Texture comparison mode	`gl.NONE` (default value), `gl.COMPARE_REF_TO_TEXTURE`.
`gl.TEXTURE_MAX_LEVEL`	Maximum texture mipmap array level	Any int values.
`gl.TEXTURE_MAX_LOD`	Texture maximum level-of-detail value	Any float values.
`gl.TEXTURE_MIN_LOD`	Texture minimum level-of-detail value	Any float values.
`gl.TEXTURE_WRAP_R`	Wrapping function for texture coordinate `r`	`gl.REPEAT` (default value), `gl.CLAMP_TO_EDGE`, `gl.MIRRORED_REPEAT`.

Return value

None (undefined).
