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.
ext.RGBA32F_EXTRGBA 32-bit floating-point color-renderable format.
ext.RGB32F_EXT ( Deprecated )RGB 32-bit floating-point color-renderable format.
ext.FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE_EXT?
ext.UNSIGNED_NORMALIZED_EXT?
This extension extends WebGLRenderingContext.renderbufferStorage():
internalformat parameter now accepts ext.RGBA32F_EXT and ext.RGB32F_EXT ( Deprecated ).js
const ext = gl.getExtension("WEBGL_color_buffer_float"); gl.renderbufferStorage(gl.RENDERBUFFER, ext.RGBA32F_EXT, 256, 256);
