The WEBGL_color_buffer_float
extension is part of the WebGL API and adds the ability to render to 32-bit floating-point color buffers.
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 1 contexts only. For WebGL 2, use the EXT_color_buffer_float
extension.
The OES_texture_float
extension implicitly enables this extension.
Constants
ext.RGBA32F_EXT
- RGBA 32-bit floating-point color-renderable format.
ext.RGB32F_EXT
( )- RGB 32-bit floating-point color-renderable format.
ext.FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE_EXT

Extended methods
This extension extends WebGLRenderingContext.renderbufferStorage()
:
- The

parameter now acceptsext.RGBA32F_EXT
andext.RGB32F_EXT
( ).
Examples
var ext = gl.getExtension('WEBGL_color_buffer_float'); gl.renderbufferStorage(gl.RENDERBUFFER, ext.RBGA32F_EXT, 256, 256);
