EggRenderMode¶

class
EggRenderMode
¶ This class stores miscellaneous rendering properties that is associated with geometry, and which may be set on the geometry primitive level, on the group above it, or indirectly via a texture. It’s intended to be a base class for egg objects that can have these properties set.
This class cannot inherit from
EggObject
, because it causes problems at theEggPolygon
level with multiple appearances of theEggObject
base class. And makingEggObject
a virtual base class is just no fun.Inheritance diagram

clearDepthOffset
()¶ Removes the depth-offset flag from this particular object. See
setDepthOffset()
.
-
clearDrawOrder
()¶ Removes the draw-order flag from this particular object. See
setDrawOrder()
.
-
getAlphaMode
() → AlphaMode¶ Returns the alpha mode that was set, or AM_unspecified if nothing was set. See
setAlphaMode()
.
-
getBin
() → str¶ Returns the bin name that has been set for this particular object, if any. See
setBin()
.
-
static
getClassType
() → panda3d.core.TypeHandle¶
-
getDepthOffset
() → int¶ Returns the “depth-offset” flag as set for this particular object. See
setDepthOffset()
.
-
getDepthTestMode
() → DepthTestMode¶ Returns the depth_test mode that was set, or DTM_unspecified if nothing was set. See
setDepthTestMode()
.
-
getDepthWriteMode
() → DepthWriteMode¶ Returns the depth_write mode that was set, or DWM_unspecified if nothing was set. See
setDepthWriteMode()
.
-
getDrawOrder
() → int¶ Returns the “draw-order” flag as set for this particular object. See
setDrawOrder()
.
-
getVisibilityMode
() → VisibilityMode¶ Returns the visibility mode that was set, or VM_unspecified if nothing was set. See
setVisibilityMode()
.
-
hasDepthOffset
() → bool¶ Returns true if the depth-offset flag has been set for this particular object. See
setDepthOffset()
.
-
hasDrawOrder
() → bool¶ Returns true if the draw-order flag has been set for this particular object. See
setDrawOrder()
.
-
setAlphaMode
(mode: AlphaMode)¶ Specifies precisely how the transparency for this geometry should be achieved, or if it should be used. The default, AM_unspecified, is to use transparency if the geometry has a color whose alpha value is non-1, or if it has a four-channel texture applied; otherwise, AM_on forces transparency on, and AM_off forces it off. The other flavors of transparency are specific ways to turn on transparency, which may or may not be supported by a particular rendering backend.
-
setBin
(bin: str)¶ Sets the “bin” string for this particular object. This names a particular bin in which the object should be rendered. The exact meaning of a bin is implementation defined, but generally a GeomBin matching each bin name must also be specifically added to the rendering engine (e.g. the
CullTraverser
) in use for this to work. See alsosetDrawOrder()
.
-
setDepthOffset
(bias: int)¶ Sets the “depth-offset” flag associated with this object. This adds or subtracts an offset bias into the depth buffer. See also
DepthOffsetAttrib
andNodePath.setDepthOffset()
.
-
setDepthTestMode
(mode: DepthTestMode)¶ Specifies whether this geometry should be tested against the depth buffer when it is drawn (assuming the rendering backend provides a depth buffer). Note that this is different, and independent from, the depth_write mode.
-
setDepthWriteMode
(mode: DepthWriteMode)¶ Specifies whether writes should be made to the depth buffer (assuming the rendering backend provides a depth buffer) when rendering this geometry.
-
setDrawOrder
(order: int)¶ Sets the “draw-order” flag associated with this object. This specifies a particular order in which objects of this type should be drawn, within the specified bin. If a bin is not explicitly specified, “fixed” is used. See also
setBin()
.
-
setVisibilityMode
(mode: VisibilityMode)¶ Specifies whether this geometry is to be considered normally visible, or hidden. If it is hidden, it is either not loaded into the scene graph at all, or loaded as a “stashed” node, according to the setting of egg- suppress-hidden.

static
stringAlphaMode
(string: str) → AlphaMode¶ Returns the
AlphaMode
value associated with the given string representation, or AM_unspecified if the string does not match any knownAlphaMode
value.
-
static
stringDepthTestMode
(string: str) → DepthTestMode¶ Returns the
DepthTestMode
value associated with the given string representation, or DTM_unspecified if the string does not match any knownDepthTestMode
value.
-
static
stringDepthWriteMode
(string: str) → DepthWriteMode¶ Returns the
DepthWriteMode
value associated with the given string representation, or DWM_unspecified if the string does not match any knownDepthWriteMode
value.
-
static
stringVisibilityMode
(string: str) → VisibilityMode¶ Returns the HiddenMode value associated with the given string representation, or VM_unspecified if the string does not match any known HiddenMode value.
-
write
(out: panda3d.core.ostream, indent_level: int)¶ Writes the attributes to the indicated output stream in Egg format.
