TexGenAttrib¶

from acron.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.

add_stage()¶

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 get_class_slot()¶

static get_class_type()¶

get_constant_value()¶: Returns the constant value associated with the named texture stage. This is only meaningful if the mode is M_constant.

get_geom_rendering()¶: 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.

get_mode()¶: Returns the generation mode associated with the named texture stage, or M_off if nothing is associated with the indicated stage.

has_gen_texcoord_stage()¶: 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).

has_stage()¶: 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).

is_empty()¶: Returns true if no stages are defined in the TexGenAttrib, false if at least one is.

static make()¶

Constructs a TexGenAttrib that generates no stages at all.

Constructs a TexGenAttrib that generates just the indicated stage.

static make_default()¶: Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.

remove_stage()¶: Returns a new TexGenAttrib just like this one, with the indicated stage removed.
