WEBGL_color_buffer_float 扩展属于 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 使用扩展在 WebGL 教程 .

可用性： This extension is available to WebGL 1 contexts only. For WebGL 2 ，使用 EXT_color_buffer_float extension.

OES_texture_float extension implicitly enables this extension.

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

var ext = gl.getExtension('WEBGL_color_buffer_float');
gl.renderbufferStorage(gl.RENDERBUFFER, ext.RBGA32F_EXT, 256, 256);
