WebGLRenderingContext.texParameter[fi]() - Web APIs 编辑
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
GLenumspecifying 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
gl.texParameterf(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.LINEAR);
gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.LINEAR_MIPMAP_NEAREST);
