The EXT_color_buffer_float
extension is part of WebGL and adds the ability to render a variety of floating point formats.
WebGL extensions are available using the WebGLRenderingContext.getExtension()
method. For more information, see also Using Extensions in the WebGL tutorial.
The following sized formats become color-renderable:
gl.R16F
,gl.RG16F
,gl.RGBA16F
,gl.R32F
,gl.RG32F
,gl.RGBA32F
,gl.R11F_G11F_B10F
.Color-renderable means:
WebGLRenderingContext.renderbufferStorage()
method now accepts these formats.gl
must be a WebGL2RenderingContext
. This extension does not work in WebGL 1 contexts.
const ext = gl.getExtension("EXT_color_buffer_float");
gl.renderbufferStorage(gl.RENDERBUFFER, gl.RGBA16F, 256, 256);
