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.
Availability: 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.
ext.RGBA32F_EXT
ext.RGB32F_EXT
()ext.FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE_EXT
ext.UNSIGNED_NORMALIZED_EXT
This extension extends WebGLRenderingContext.renderbufferStorage()
:
internalformat
parameter now accepts ext.RGBA32F_EXT
and ext.RGB32F_EXT
().var ext = gl.getExtension('WEBGL_color_buffer_float'); gl.renderbufferStorage(gl.RENDERBUFFER, ext.RBGA32F_EXT, 256, 256);
