{{APIRef("WebGL")}}

The OES_texture_float_linear extension is part of the WebGL API and allows linear filtering with floating-point pixel types for textures.

WebGL extensions are available using the {{domxref("WebGLRenderingContext.getExtension()")}} method. For more information, see also Using Extensions in the WebGL tutorial.

Note: This extension is available to both, {{domxref("WebGLRenderingContext", "WebGL1", "", 1)}} and {{domxref("WebGL2RenderingContext", "WebGL2", "", 1)}} contexts.

Linear filtering

The {{domxref("OES_texture_float")}} extension alone does not allow linear filtering with 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 {{domxref("WebGLRenderingContext.texParameter()")}} method to one of gl.LINEAR, gl.LINEAR_MIPMAP_NEAREST, gl.NEAREST_MIPMAP_LINEAR, or gl.LINEAR_MIPMAP_LINEAR, and use floating-point textures.

Examples

gl.getExtension("OES_texture_float");
gl.getExtension("OES_texture_float_linear");

const 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, gl.FLOAT, image);
