TexGenAttrib

from panda3d.core import TexGenAttrib
class TexGenAttrib

Bases: RenderAttrib

Computes 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.

Inheritance diagram

Inheritance diagram of TexGenAttrib

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.

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.

property class_slotint
static getClassSlot()int
static getClassType()TypeHandle
getConstantValue(stage: TextureStage)LTexCoord3

Returns the constant value associated with the named texture stage. This is only meaningful if the mode is M_constant.

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.

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.

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).

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).

isEmpty()bool

Returns true if no stages are defined in the TexGenAttrib, false if at least one is.

static make()RenderAttrib

Constructs a TexGenAttrib that generates no stages at all.

static make(stage: TextureStage, mode: Mode)RenderAttrib

Constructs a TexGenAttrib that generates just the indicated stage.

static makeDefault()RenderAttrib

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

removeStage(stage: TextureStage)RenderAttrib

Returns a new TexGenAttrib just like this one, with the indicated stage removed.
