OES_texture_half_float_linear 扩展属于 WebGL API and allows linear filtering with half floating-point pixel types for textures.

WebGL extensions are available using the WebGLRenderingContext.getExtension() method. For more information, see also 使用扩展在 WebGL 教程 .

可用性： This extension is available to both, WebGL1 and WebGL2 上下文。

Linear filtering

OES_texture_half_float extension alone does not allow linear filtering with half floating-point textures. This extension enables this ability.

With the help of this extension, you can now set the magnification or minification filter in the WebGLRenderingContext.texParameter() method to one of gl.LINEAR , gl.LINEAR_MIPMAP_NEAREST , gl.NEAREST_MIPMAP_LINEAR ，或 gl.LINEAR_MIPMAP_LINEAR , and use half floating-point textures.

范例

var halfFloat = gl.getExtension('OES_texture_half_float');
gl.getExtension('OES_texture_half_float_linear');
var texture = gl.createTexture();
gl.bindTexture(gl.TEXTURE_2D, texture);
gl.texParameterf(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.LINEAR);
gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, halfFloat.HALF_FLOAT_OES, image);
