TexGenAttrib

from panda3d.core import TexGenAttrib

class TexGenAttrib

Bases:

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

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_slot → int

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.
