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 the EggPolygon level with multiple appearances of the EggObject base class. And making EggObject a virtual base class is just no fun.
Inheritance diagram
-
__init__() → None¶
-
__init__(copy: EggRenderMode) → None
-
assign(copy: EggRenderMode) → EggRenderMode¶ - Return type
-
write(out: ostream, indent_level: int) → None¶ Writes the attributes to the indicated output stream in Egg format.
-
setAlphaMode(mode: AlphaMode) → None¶ 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.
-
getAlphaMode() → AlphaMode¶ Returns the alpha mode that was set, or AM_unspecified if nothing was set. See
setAlphaMode().- Return type
AlphaMode
-
setDepthWriteMode(mode: DepthWriteMode) → None¶ Specifies whether writes should be made to the depth buffer (assuming the rendering backend provides a depth buffer) when rendering this geometry.
-
getDepthWriteMode() → DepthWriteMode¶ Returns the depth_write mode that was set, or DWM_unspecified if nothing was set. See
setDepthWriteMode().- Return type
DepthWriteMode
-
setDepthTestMode(mode: DepthTestMode) → None¶ 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.
-
getDepthTestMode() → DepthTestMode¶ Returns the depth_test mode that was set, or DTM_unspecified if nothing was set. See
setDepthTestMode().- Return type
DepthTestMode
-
setVisibilityMode(mode: VisibilityMode) → None¶ 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.
-
getVisibilityMode() → VisibilityMode¶ Returns the visibility mode that was set, or VM_unspecified if nothing was set. See
setVisibilityMode().- Return type
VisibilityMode
-
setDepthOffset(bias: int) → None¶ Sets the “depth-offset” flag associated with this object. This adds or subtracts an offset bias into the depth buffer. See also DepthOffsetAttrib and NodePath::set_depth_offset().
-
getDepthOffset() → int¶ Returns the “depth-offset” flag as set for this particular object. See
setDepthOffset().
-
hasDepthOffset() → bool¶ Returns true if the depth-offset flag has been set for this particular object. See
setDepthOffset().
-
clearDepthOffset() → None¶ Removes the depth-offset flag from this particular object. See
setDepthOffset().
-
setDrawOrder(order: int) → None¶ 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().
-
getDrawOrder() → int¶ Returns the “draw-order” flag as set for this particular object. See
setDrawOrder().
-
hasDrawOrder() → bool¶ Returns true if the draw-order flag has been set for this particular object. See
setDrawOrder().
-
clearDrawOrder() → None¶ Removes the draw-order flag from this particular object. See
setDrawOrder().
-
setBin(bin: str) → None¶ 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 also
setDrawOrder().
-
getBin() → str¶ Returns the bin name that has been set for this particular object, if any. See
setBin().
-
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 known AlphaMode value.
- Return type
AlphaMode

stringDepthWriteMode(string: str) → DepthWriteMode¶ Returns the DepthWriteMode value associated with the given string representation, or DWM_unspecified if the string does not match any known DepthWriteMode value.
- Return type
DepthWriteMode

stringDepthTestMode(string: str) → DepthTestMode¶ Returns the DepthTestMode value associated with the given string representation, or DTM_unspecified if the string does not match any known DepthTestMode value.
- Return type

-
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.
