The EXT_color_buffer_half_float extension is part of the WebGL API and adds the ability to render to 16-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_half_float extension implicitly enables this extension.
ext.RGBA16F_EXText.RGB16F_EXText.FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE_EXText.UNSIGNED_NORMALIZED_EXTThis extension extends WebGLRenderingContext.renderbufferStorage():
internalformat parameter now accepts ext.RGBA16F_EXT and ext.RGBA16F_EXT.var ext = gl.getExtension('EXT_color_buffer_half_float');
gl.renderbufferStorage(gl.RENDERBUFFER, ext.RBGA16F_EXT, 256, 256);
