在此页

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

句法 

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

参数

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.
  • 当使用 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.

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 描述 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 值。
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 .

返回值

None.

范例 

gl.texParameterf(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.LINEAR);
gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.LINEAR_MIPMAP_NEAREST);
