| |
| 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. |
