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.

`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.
