OVR_multiview2: framebufferTextureMultiviewOVR() method
The OVR_multiview2.framebufferTextureMultiviewOVR()
method of the WebGL API attaches a multiview
texture to a WebGLFramebuffer
.
Syntax
framebufferTextureMultiviewOVR(target, attachment, texture, level, baseViewIndex, numViews)
Parameters
target
-
A
GLenum
specifying the binding point (target). Possible values:gl.FRAMEBUFFER
-
Collection buffer data storage of color, alpha, depth and stencil buffers used to render an image.
gl.DRAW_FRAMEBUFFER
-
Equivalent to
gl.FRAMEBUFFER
. Used as a destination for drawing, rendering, clearing, and writing operations. gl.READ_FRAMEBUFFER
-
Used as a source for reading operations.
attachment
-
A
GLenum
specifying the attachment point for thetexture
. Possible values:-
gl.COLOR_ATTACHMENT0
: Attaches the texture to the framebuffer's color buffer. -
gl.DEPTH_ATTACHMENT
: Attaches the texture to the framebuffer's depth buffer. -
gl.STENCIL_ATTACHMENT
: Attaches the texture to the framebuffer's stencil buffer. gl.DEPTH_STENCIL_ATTACHMENT
: depth and stencil buffer.-
gl.COLOR_ATTACHMENT1 gl.COLOR_ATTACHMENT2 gl.COLOR_ATTACHMENT3 gl.COLOR_ATTACHMENT4 gl.COLOR_ATTACHMENT5 gl.COLOR_ATTACHMENT6 gl.COLOR_ATTACHMENT7 gl.COLOR_ATTACHMENT8 gl.COLOR_ATTACHMENT9 gl.COLOR_ATTACHMENT10 gl.COLOR_ATTACHMENT11 gl.COLOR_ATTACHMENT12 gl.COLOR_ATTACHMENT13 gl.COLOR_ATTACHMENT14 gl.COLOR_ATTACHMENT15

-
When using the
WEBGL_depth_texture
extension:-
ext.DEPTH_STENCIL_ATTACHMENT
: Depth and stencil buffer data storage.
-
texture
-
A
WebGLTexture
object whose image to attach. level
-
A
GLint
specifying the mipmap level of the texture image to be attached. Must be 0. baseViewIndex
-
A
GLint
specifying the base view index of the framebuffer object attachment. numViews
-
A
GLsizei
specifying the number of views of the framebuffer object attachment.
Return value
None (undefined
).
Exceptions
- A
gl.INVALID_ENUM
error is thrown iftarget
is notgl.FRAMEBUFFER
.attachment
is not one of the accepted attachment points.
- A
gl.INVALID_VALUE
error is thrown iflevel
is not 0.-
if
numViews
is less than one or more thanMAX_VIEWS_OVR
.
-
A
gl.INVALID_OPERATION
error is thrown iftexture
isn't 0 or the name of an existing texture object.
Examples
