panda3d.core.TransparencyAttrib¶

from panda3d.core import TransparencyAttrib

class TransparencyAttrib¶

Bases: RenderAttrib

This controls the enabling of transparency. Simply setting an alpha component to non-1 does not in itself make an object transparent; you must also enable transparency mode with a suitable TransparencyAttrib. Similarly, it is wasteful to render an object with a TransparencyAttrib in effect unless you actually want it to be at least partially transparent (and it has alpha components less than 1).

Inheritance diagram

static make(mode: Mode) → RenderAttrib¶

Constructs a new TransparencyAttrib object.

Return type: RenderAttrib

static makeDefault() → RenderAttrib¶

Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.

Return type: RenderAttrib

getMode() → Mode¶

Returns the transparency mode.

Return type: Mode

static getClassSlot() → int¶

static getClassType() → TypeHandle¶

Return type: TypeHandle

property mode¶

Returns the transparency mode.

Return type: Mode

property class_slot¶

Return type: int

enum Mode

enumerator M_none = 0: No transparency.

enumerator M_alpha = 1¶: Normal transparency, panda will sort back-to-front.

enumerator M_premultiplied_alpha = 2¶: Assume textures use premultiplied alpha.

enumerator M_multisample = 3: Uses ms buffer, alpha values modified to 1.0.

enumerator M_multisample_mask = 4¶: Uses ms buffer, alpha values not modified.

enumerator M_binary = 5¶: Only writes pixels with alpha >= 0.5.

enumerator M_dual = 6¶: opaque parts first, then sorted transparent parts.
