panda3d.core.TexGenAttrib¶
-
class
TexGenAttrib¶ Bases:
RenderAttribComputes texture coordinates for geometry automatically based on vertex position and/or normal. This can be used to implement reflection and/or refraction maps, for instance to make shiny surfaces, as well as other special effects such as projective texturing.

-
static
make() → RenderAttrib¶ Constructs a TexGenAttrib that generates no stages at all.
- Return type
-
static
make(stage: TextureStage, mode: Mode) → RenderAttrib Constructs a TexGenAttrib that generates just the indicated stage.
- Return type
-
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
-
addStage(stage: TextureStage, mode: Mode) → RenderAttrib¶ Returns a new TexGenAttrib just like this one, with the indicated generation mode for the given stage. If this stage already exists, its mode is replaced.
- Return type
-
addStage(stage: TextureStage, mode: Mode, constant_value: LTexCoord3) → RenderAttrib Returns a new TexGenAttrib just like this one, with the indicated generation mode for the given stage. If this stage already exists, its mode is replaced.
This variant also accepts constant_value, which is only meaningful if mode is M_constant.
- Return type
-
removeStage(stage: TextureStage) → RenderAttrib¶ Returns a new TexGenAttrib just like this one, with the indicated stage removed.
- Return type
-
isEmpty() → bool¶ Returns true if no stages are defined in the TexGenAttrib, false if at least one is.
-
hasStage(stage: TextureStage) → bool¶ Returns true if there is a mode associated with the indicated stage, or false otherwise (in which case get_transform(stage) will return M_off).
-
getMode(stage: TextureStage) → Mode¶ Returns the generation mode associated with the named texture stage, or M_off if nothing is associated with the indicated stage.
- Return type
Mode
-
hasGenTexcoordStage(stage: TextureStage) → bool¶ Returns true if the indicated TextureStage will have texture coordinates generated for it automatically (and thus there is no need to upload the texture coordinates encoded in the vertices).
-
getConstantValue(stage: TextureStage) → LTexCoord3¶ Returns the constant value associated with the named texture stage. This is only meaningful if the mode is M_constant.
- Return type
LTexCoord3
-
getGeomRendering(geom_rendering: int) → int¶ Returns the union of the Geom::GeomRendering bits that will be required once this TexGenAttrib is applied to a geom which includes the indicated geom_rendering bits.
