WebGLRenderingContext.texParameter[fi]()

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.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.

Examples
