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.
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.
