OpenGL ES 2.0 is required.

|
Overview
|
||
|
|
|
||
|
|
Adds a query for a serialized string representation of a context.
|
||
|
|
Useful for testing to easily compare two states.

New Tokens
|
||
|
|
|
||
|
|
Accepted by the <name> parameter of glGetString:
|
||
|
|
|
||
|
|
SERIALIZED_CONTEXT_STRING_ANGLE 0x96B0
|
||
|
|
|
||
|
|
Additions to Chapter 6 of the OpenGL ES 2.0 Specification (Querying GL State)
|
||
|
|
|
||
|
|
Update Section 6.1.5 "String Queries" to accept the new enum specified
|
||
|
|
above. The SERIALIZED_CONTEXT_STRING_ANGLE string is an implementation-
|
||
|
|
dependent representation of the current context state. Two contexts
|
||
|
|
with the same internal state are guaranteed to have the same value. Note
|
||
|
|
that the reverse is not true - two contexts with different states are
|
||
|
|
may also have the same serialized string.
|
||
|
|
|
||
|
|
New State
|
||
|
|
|
||
|
|
None.

|
Issues
|
||
|
|
|
||
|
|
1) Should two contexts with different states return different strings?
|
||
|
|
|
||
|
|
RESOLVED: We don't provide a guarantee that every state is serialized
|
||
|
|
into the string. This loose wording lets the extension provide
|
||
|
|
some additional extra validation without being overly strict and
|
||
|
|
making the implementation difficult. It also allow a no-op
|
||
|
|
implementation to satisfy the extension requirements.
