Macro Definition Documentation

#define VEX_OPTIMIZE_0   0

Perform no optimization on the VEX function

Warning

this may impact performance severely.

Examples:

VEX/VEX_Example.C, and VEX/VEX_Ops.C.

Definition at line 126 of file VEX_VexOp.h.

#define VEX_OPTIMIZE_1   1

If the result of the function is unused, the function can be eliminated.

Examples:

VEX/VEX_Example.C, and VEX/VEX_Ops.C.

Definition at line 127 of file VEX_VexOp.h.

#define VEX_OPTIMIZE_2   2

Definition at line 128 of file VEX_VexOp.h.

Typedef Documentation

typedef void(* VEX_VexOpCallback)(int argc, void *argv[], void *data)

VEX operator evaluation callback. When called, the data returned by the VEX_VexOpInit function will be passed as the "data" argument.

Definition at line 89 of file VEX_VexOp.h.

typedef void(* VEX_VexOpCleanup)(void *data)

VEX operator cleanup callback. When called, it should deallocate the data.

Definition at line 97 of file VEX_VexOp.h.

typedef void(* VEX_VexOpCompleted)(void *data)

VEX operator completed callback. Called when a shader that evaluated a custom operator completes.

Definition at line 100 of file VEX_VexOp.h.

typedef void*(* VEX_VexOpInit)()

VEX operator initialization callback. When called, it should allocated and initialize custom state data.

Definition at line 86 of file VEX_VexOp.h.

typedef void(* VEX_VexOpTypedCallback)(int argc, VEX_VexOpArg argv[], void *data)

VEX operator evaluation callback with argument type information. This version of the operator callback must be used for variadic functions. When called, the data returned by the VEX_VexOpInit function will be passed as the "data" argument.

Definition at line 94 of file VEX_VexOp.h.
