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 使用扩展 在 WebGL 教程 .

可用性： This extension is available to WebGL 2 contexts only.

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:

• WebGLRenderingContext.renderbufferStorage() method now accepts these formats.
• Framebuffers with attached textures of these formats may now be FRAMEBUFFER_COMPLETE .

范例

gl 必须为 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);
