WebGLRenderingContext.texParameter

The WebGLRenderingContext.texParameter[fi]() methods of the WebGL API set texture parameters.

Syntax

void gl.texParameterf(GLenum target, GLenum pname, GLfloat param);
void gl.texParameteri(GLenum target, GLenum pname, GLint 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.

The pname parameter is a Glenum specifying the texture parameter to set. The param parameter is a GLfloat or GLint specifying the value for the specified parameter pname.

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.NOT_EQUAL, 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.

Examples
