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
.
