WebGLRenderingContext.renderbufferStorage() 方法在 WebGL API creates and initializes a renderbuffer object's data store.

句法

void gl.renderbufferStorage(target, internalFormat, width, height);
					

参数

target

Glenum specifying the target renderbuffer object. Possible values:

• gl.RENDERBUFFER : Buffer data storage for single images in a renderable internal format.

internalFormat

Glenum specifying the internal format of the renderbuffer. Possible values:

• gl.RGBA4 : 4 red bits, 4 green bits, 4 blue bits 4 alpha bits.
• gl.RGB565 : 5 red bits, 6 green bits, 5 blue bits.
• gl.RGB5_A1 : 5 red bits, 5 green bits, 5 blue bits, 1 alpha bit.
• gl.DEPTH_COMPONENT16 : 16 depth bits.
• gl.STENCIL_INDEX8 : 8 stencil bits.
• gl.DEPTH_STENCIL
• 当使用 WebGL 2 context , the following values are available additionally:
  • gl.R8
  • gl.R8UI
  • gl.R8I
  • gl.R16UI
  • gl.R16I
  • gl.R32UI
  • gl.R32I
  • gl.RG8
  • gl.RG8UI
  • gl.RG8I
  • gl.RG16UI
  • gl.RG16I

• 当使用 WEBGL_color_buffer_float extension:
  • ext.RGBA32F_EXT : RGBA 32-bit floating-point type.
  • ext.RGB32F_EXT : RGB 32-bit floating-point type.
• 当使用 EXT_sRGB extension:
  • ext.SRGB8_ALPHA8_EXT : 8-bit sRGB and alpha.
• 当使用 WebGL 2 context 和 EXT_color_buffer_float extension:
  • gl.R16F
  • gl.RG16F
  • gl.RGBA16F
  • gl.R32F
  • gl.RG32F
  • gl.RGBA32F
  • gl.R11F_G11F_B10F

width

GLsizei specifying the width of the renderbuffer in pixels.

height

GLsizei specifying the height of the renderbuffer in pixels.

返回值

None.

范例
