WEBGL_color_buffer_float
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.
Note: 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-
?
ext.UNSIGNED_NORMALIZED_EXT-
?
Extended methods
This extension extends WebGLRenderingContext.renderbufferStorage():
- The
internalformatparameter now acceptsext.RGBA32F_EXTandext.RGB32F_EXT().
Examples
var ext = gl.getExtension('WEBGL_color_buffer_float'); gl.renderbufferStorage(gl.RENDERBUFFER, ext.RGBA32F_EXT, 256, 256);
