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.

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 internalformat parameter now accepts ext.RGBA32F_EXT and ext.RGB32F_EXT ().

Examples

var ext = gl.getExtension('WEBGL_color_buffer_float');

gl.renderbufferStorage(gl.RENDERBUFFER, ext.RBGA32F_EXT, 256, 256);
