WEBGL_color_buffer_float

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 WebGL tutorial .

Availability: This extension is available to WebGL 1 contexts only. For WebGL 2 , use the EXT_color_buffer_float extension.

OES_texture_float extension implicitly enables this extension.

常量

ext.RGBA32F_EXT
RGBA 32-bit floating-point color-renderable format.
ext.RGB32F_EXT ( )
RGB 32-bit floating-point color-renderable format.
ext.FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE_EXT
?
ext.UNSIGNED_NORMALIZED_EXT
?

Extended methods

This extension extends WebGLRenderingContext.renderbufferStorage() :

  • internalformat parameter now accepts ext.RGBA32F_EXT and ext.RGB32F_EXT ( ).

范例

var ext = gl.getExtension('WEBGL_color_buffer_float');
gl.renderbufferStorage(gl.RENDERBUFFER, ext.RBGA32F_EXT, 256, 256);
