{{APIRef("WebGL")}}
The OES_texture_half_float
extension is part of the WebGL API and adds texture formats with 16- (aka half float) and 32-bit floating-point components.
WebGL extensions are available using the {{domxref("WebGLRenderingContext.getExtension()")}} method. For more information, see also Using Extensions in the WebGL tutorial.
Constants
ext.HALF_FLOAT_OES
- Half floating-point type (16-bit).
Extended methods
This extension extends {{domxref("WebGLRenderingContext.texImage2D()")}} and {{domxref("WebGLRenderingContext.texSubImage2D()")}}:
- The
type
parameter now acceptsext.HALF_FLOAT_OES
.
Examples
var ext = gl.getExtension("OES_texture_half_float"); var texture = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, texture); gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, ext.HALF_FLOAT_OES, image);
