WEBGL_color_buffer_float extension
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.
TheWEBGL_color_buffer_float extension is part of theWebGL API and adds the ability to render to 32-bit floating-point color buffers.
WebGL extensions are available using theWebGLRenderingContext.getExtension() method. For more information, see alsoUsing Extensions in theWebGL tutorial.
Note:This extension is available toWebGL 1 contexts only. ForWebGL 2, use theEXT_color_buffer_float extension.
TheOES_texture_float extension implicitly enables this extension.
