|
Overview
|
|
|
|
For internal use of ANGLE for GLES1 emulation, through this extension the
|
|
backend lets the frontend know that the equivalent of glLogicOp is natively
|
|
supported and can be used.
|
|
|
|
New Procedures and Functions
|
|
|
|
The following commands are added:
|
|
|
|
void LogicOpANGLE(enum op);
|
|
|
|
New Tokens
|
|
|
|
The following tokens are added:
|
|
|
|
Accepted by the <cap> parameter of Enable, Disable, and IsEnabled:
|
|
|
|
COLOR_LOGIC_OP_ANGLE 0x0BF2
|
|
|
|
Accepted by the <op> parameter of LogicOpANGLE:
|
|
|
|
LOGIC_OP_CLEAR_ANGLE 0x1500
|
|
LOGIC_OP_AND_ANGLE 0x1501
|
|
LOGIC_OP_AND_REVERSE_ANGLE 0x1502
|
|
LOGIC_OP_COPY_ANGLE 0x1503
|
|
LOGIC_OP_AND_INVERTED_ANGLE 0x1504
|
|
LOGIC_OP_NOOP_ANGLE 0x1505
|
|
LOGIC_OP_XOR_ANGLE 0x1506
|
|
LOGIC_OP_OR_ANGLE 0x1507
|
|
LOGIC_OP_NOR_ANGLE 0x1508
|
|
LOGIC_OP_EQUIV_ANGLE 0x1509
|
|
LOGIC_OP_INVERT_ANGLE 0x150A
|
|
LOGIC_OP_OR_REVERSE_ANGLE 0x150B
|
|
LOGIC_OP_COPY_INVERTED_ANGLE 0x150C
|
|
LOGIC_OP_OR_INVERTED_ANGLE 0x150D
|
|
LOGIC_OP_NAND_ANGLE 0x150E
|
|
LOGIC_OP_SET_ANGLE 0x150F
|
|
|
|
The semantics of LogicOpANGLE and COLOR_LOGIC_OP_ANGLE are identical to LogicOp
|
|
and COLOR_LOGIC_OP in the OpenGL ES 1.0 specification.
