OpenGL ES Extension XX
|
|
|
|
Dependencies
|
|
|
|
OpenGL ES 3.0 and the extensions ANGLE_texture_multisample, OVR_multiview2
|
|
and OES_texture_storage_multisample_2d_array are required.
|
|
|
|
With OpenGL ES 3.1, only the extensions ANGLE_multiview and
|
|
OES_texture_storage_multisample_2d_array are required.
|
|
|
|
Overview
|
|
|
|
This extension enhances the functionality introduced in ANGLE_multiview by
|
|
enabling rendering into multisample texture arrays in addition to regular
|
|
non-multisampled texture arrays.

Additions to Chapter 4 of the OpenGL ES 3.0 Specification
|
|
(Per-Fragment Operations and the Framebuffer)
|
|
|
|
Modify section 4.4.2 (Attaching Images to Framebuffer Objects), p. 202
|
|
|
|
Add the following bullet point:
|
|
|
|
"* Layers of a two-dimensional multisample array texture which can be used
|
|
for multi-view rendering."
|
|
|
|
Modify the error list of FramebufferTextureMultiviewOVR:
|
|
|
|
Change
|
|
|
|
"An INVALID_OPERATION error is generated if texture is not zero,
|
|
and does not name an existing texture object of type TEXTURE_2D_ARRAY."
|
|
|
|
to
|
|
|
|
"An INVALID_OPERATION error is generated if texture is not zero,
|
|
and does not name an existing texture object of type TEXTURE_2D_ARRAY or
|
|
TEXTURE_2D_MULTISAMPLE_ARRAY_OES."
|
|
|
|
|
|
Modify section 4.4.4.1 (Framebuffer Attachment Completeness), p. 213
|
|
|
|
Change the bullet point about num_views and base_view_index:
|
|
|
|
"If the value of FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is TEXTURE and
|
|
the value of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME names a two-dimensional
|
|
array texture or a two-dimensional multisample array texture, then the sum
|
|
of FRAMEBUFFER_ATTACHMENT_TEXTURE_NUM_VIEWS_ANGLE and
|
|
FRAMEBUFFER_ATTACHMENT_TEXTURE_BASE_VIEW_INDEX_ANGLE must be less than the
|
|
number of layers in the texture."
