For WebGL 1 ,见 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:

范例

gl 必须是 WebGL2RenderingContext . This extension does not work in WebGL 1 contexts.

var ext = gl.getExtension('EXT_color_buffer_float');
gl.renderbufferStorage(gl.RENDERBUFFER, gl.RGBA16F, 256, 256);
