EXT_color_buffer_float

The EXT_color_buffer_float extension is part of WebGL and adds the ability to render a variety of floating point formats.

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 2 contexts only.

For WebGL 1, see the EXT_color_buffer_half_float and WEBGL_color_buffer_float extensions.

Extended methods

The following sized formats become color-renderable:

  • gl.R16F,
  • gl.RG16F,
  • gl.RGBA16F,
  • gl.R32F,
  • gl.RG32F,
  • gl.RGBA32F,
  • gl.R11F_G11F_B10F.

Color-renderable means:

Examples

gl must be a WebGL2RenderingContext. This extension does not work in WebGL 1 contexts.

var ext = gl.getExtension("EXT_color_buffer_float");

gl.renderbufferStorage(gl.RENDERBUFFER, gl.RBGA16F, 256, 256);
