LogicOpAttrib

from panda3d.core import LogicOpAttrib

class LogicOpAttrib

Bases:

Bases: RenderAttrib

If enabled, specifies that a custom logical operation be performed instead of any color blending. Setting it to a value other than M_none will cause color blending to be disabled and the given logic operation to be performed.

New in version 1.10.0.

enum Operation

enumerator O_none = 0: LogicOp disabled, regular blending occurs.

enumerator O_clear = 1: Clears framebuffer value.

enumerator O_and = 2

enumerator O_and_reverse = 3

enumerator O_copy = 4: Writes the incoming color to the framebuffer.

enumerator O_and_inverted = 5

enumerator O_noop = 6: Leaves the framebuffer value unaltered.

enumerator O_xor = 7

enumerator O_or = 8

enumerator O_nor = 9

enumerator O_equivalent = 10

enumerator O_invert = 11

enumerator O_or_reverse = 12

enumerator O_copy_inverted = 13

enumerator O_or_inverted = 14

enumerator O_nand = 15

enumerator O_set = 16: Sets all the bits in the framebuffer to 1.

property class_slot → int

static get_class_slot() → int

static get_class_type() → TypeHandle

get_operation() → Operation: Returns the logic operation specified by this attribute.

static make(op: Operation) → RenderAttrib: Constructs a new LogicOpAttrib object with the given logic operation.

static make_default() → RenderAttrib: Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.

static make_off() → RenderAttrib: Constructs a new LogicOpAttrib object that disables special-effect blending, allowing normal transparency to be used instead.

property operation → Operation: Returns the logic operation specified by this attribute.
