WebGLRenderingContext: texParameter[fi]() method
The WebGLRenderingContext.texParameter[fi]()
methods of
the WebGL API set texture parameters.
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 aGLfloat
orGLint
specifying the value for the specified parameter pname
-
The
pname
parameter is aGLenum
specifying the texture parameter to set.
