EXT_texture_filter_anisotropic
扩展属于
WebGL API
和暴露了 2 个常量为
AF (各向异性过滤)
.
AF improves the quality of mipmapped texture access when viewing a textured primitive at an oblique angle. Using just mipmapping, these lookups have a tendency to average to grey.
WebGL extensions are available using the
WebGLRenderingContext.getExtension()
method. For more information, see also

可用性: This extension is available to both, WebGL1 and WebGL2 上下文。
ext.MAX_TEXTURE_MAX_ANISOTROPY_EXT
pname
自变量到
gl.getParameter()
call, and it returns the maximum available anisotropy.
ext.TEXTURE_MAX_ANISOTROPY_EXT
pname
自变量到
gl.getTexParameter()
and
gl.texParameterf()
/
gl.texParameteri()
calls and sets the desired maximum anisotropy for a texture.
var texture = gl.createTexture();
gl.bindTexture(gl.TEXTURE_2D, texture);
var ext = (
gl.getExtension('EXT_texture_filter_anisotropic') ||
gl.getExtension('MOZ_EXT_texture_filter_anisotropic') ||
gl.getExtension('WEBKIT_EXT_texture_filter_anisotropic')
);
if (ext){
var max = gl.getParameter(ext.MAX_TEXTURE_MAX_ANISOTROPY_EXT);
gl.texParameterf(gl.TEXTURE_2D, ext.TEXTURE_MAX_ANISOTROPY_EXT, max);
