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.
Availability: This extension is available to WebGL 2 contexts only.
For WebGL 1, see the EXT_color_buffer_half_float
and WEBGL_color_buffer_float
extensions.
Extended methods
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:
- The
WebGLRenderingContext.renderbufferStorage()
method now accepts these formats. - Framebuffers with attached textures of these formats may now be FRAMEBUFFER_COMPLETE.
Examples
gl
must be a WebGL2RenderingContext
. This extension does not work in WebGL 1 contexts.
var ext = gl.getExtension('EXT_color_buffer_float'); gl.renderbufferStorage(gl.RENDERBUFFER, gl.RGBA16F, 256, 256);
