Resets the multitexture flags set by multitexture_over().

After this call, get_multitexture() will return false, and get_multitexture_sort() will return 0.

Definition at line 597 of file eggTexture.cxx.

◆ determine_wrap_u()

EggTexture::WrapMode EggTexture::determine_wrap_u ( ) const

inline

References get_wrap_w.

◆ has_alpha_channel()

bool EggTexture::has_alpha_channel ( int num_components ) const

Given the number of color components (channels) in the image file as actually read from the disk, return true if this texture seems to have an alpha channel or not.

This depends on the EggTexture's format as well as the number of channels.

Referenced by TextureReference::update_egg().

◆ is_equivalent_to()

bool EggTexture::is_equivalent_to	(	const EggTexture &	other,
		int	eq
	)		const

Returns true if the two textures are equivalent in all relevant properties (according to eq), false otherwise.

The Equivalence parameter, eq, should be set to the bitwise OR of the following properties, according to what you consider relevant:

EggTexture::E_basename: The basename part of the texture filename, without the directory prefix *or* the filename extension.

EggTexture::E_extension: The extension part of the texture filename.

EggTexture::E_dirname: The directory prefix of the texture filename.

EggTexture::E_complete_filename: The union of the above three; that is, the complete filename, with directory, basename, and extension.

EggTexture::E_transform: The texture matrix.

This will guarantee that this->get_multitexture_sort() > other->get_multitexture_sort(), at least until clear_multitexture() is called on either one.

The return value is true if successful, or false if there is a failure because the other texture was already layered on top of this one (or there is a three- or more-way cycle).

Definition at line 634 of file eggTexture.cxx.

References get_multitexture_sort.

◆ sorts_less_than()

bool EggTexture::sorts_less_than	(	const EggTexture &	other,

◆ set_alpha_file_channel

void EggTexture::set_alpha_file_channel

inline

If a separate alpha-file is specified, this indicates which channel number should be extracted from this file to derive the alpha channel for the final image.

The default is 0, which means the grayscale combination of r, g, b. Otherwise, this should be the 1-based channel number, for instance 1, 2, or 3 for r, g, or b, respectively, or 4 for the alpha channel of a four-component image.

Definition at line 346 of file eggTexture.h.

◆ set_alpha_filename

void EggTexture::set_alpha_filename

inline

Specifies a separate file that will be loaded in with the 1- or 3-component texture and applied as the alpha channel.

This is useful when loading textures from file formats that do not support alpha, for instance jpg.

Definition at line 343 of file eggTexture.h.

◆ set_alpha_fullpath

void EggTexture::set_alpha_fullpath

inline

Records the full pathname to the file, for the benefit of get_alpha_fullpath().

Definition at line 344 of file eggTexture.h.

◆ set_alpha_scale

void EggTexture::set_alpha_scale

inline

Sets an additional factor that will scale the alpha component after the texture has been applied.

This is used only when a combine mode is in effect.

The only legal values are 1, 2, or 4.

Definition at line 341 of file eggTexture.h.

◆ set_anisotropic_degree

void EggTexture::set_anisotropic_degree

inline

Sets the degree of anisotropic filtering for this texture.

1 is off; higher levels indicate filtering in effect.

◆ set_lod_bias

void EggTexture::set_lod_bias

inline

Sets the mipmap level bias that is added to the mipmap level to be sampled.

Definition at line 356 of file eggTexture.h.

◆ set_max_lod

void EggTexture::set_max_lod

inline

Sets the maximum mipmap level that may be sampled.

Definition at line 354 of file eggTexture.h.

◆ set_min_lod

void EggTexture::set_min_lod

inline

Sets the minimum mipmap level that may be sampled.

Definition at line 352 of file eggTexture.h.

◆ set_multiview

void EggTexture::set_multiview

inline

Sets the multiview flag.

If multiview is true, the filename should contain a hash mark ('#'), which will be filled in with the view number; and a multiview texture will be defined with a series of images, one for each view.

A multiview texture is most often used for stereo textures, but other uses are also possible, such as for texture animation.

Definition at line 347 of file eggTexture.h.

◆ set_num_views

void EggTexture::set_num_views

inline

When loading a 3-D multiview texture, this parameter is necessary to specify how many views will be expected.

The z size is determined implicitly from the number of images loaded.

Definition at line 349 of file eggTexture.h.

◆ set_priority

void EggTexture::set_priority

inline

Sets the importance of this texture with respect to other textures also applied on the same geometry.

This is only meaningful in the presence of multitexturing.

Definition at line 331 of file eggTexture.h.

◆ set_read_mipmaps

void EggTexture::set_read_mipmaps

inline

Sets the read_mipmaps flag.

If read_mipmaps is true, the filename should contain a hash mark ('#'), which will be filled in with the mipmap level number; and the texture will be defined with a series of images, one for each mipmap level.

If the filename is of a type that already requires a hash mark, such as a cube map or a 3-d texture, then the filename should now require two hash marks, and the first one indicates the mipmap level number, while the second indicates the face number or 3-d level number.

Definition at line 350 of file eggTexture.h.

◆ set_rgb_scale

void EggTexture::set_rgb_scale

inline

Sets an additional factor that will scale all three r, g, b components after the texture has been applied.

This is used only when a combine mode is in effect.

The only legal values are 1, 2, or 4.

Definition at line 339 of file eggTexture.h.

◆ set_saved_result

void EggTexture::set_saved_result

inline

Sets the saved_result flag.

When this is true, the output of this stage is not part of the normal pipeline–that is, it will not be supplied as the "previous" source for the next texture stage–but it will instead be supplied as the "last_saved_result" source for any future stages, until the next TextureStage with a saved_result set true is encountered.

This can be used to reuse the results of this texture stage as input to more than one stage later in the pipeline.

The last texture in the pipeline (the one with the highest sort value) should not have this flag set.

Definition at line 325 of file eggTexture.h.

◆ set_stage_name

void EggTexture::set_stage_name

inline

Specifies the particular TextureStage this texture will be rendered on by name.

If this is omitted, the texture will be rendered on the default TextureStage, unless some other stage-specific property is specificied, in which case the texture will be rendered on a TextureStage with the same name as the tref. This is in support of multitexturing.

Each different TextureStage in the world must be uniquely named.

Definition at line 329 of file eggTexture.h.

◆ set_uv_name

void EggTexture::set_uv_name

inline

Specifies the named set of texture coordinates that this texture will use when it is applied to geometry.

Geometry may have multiple sets of texture coordinates defined, by name.

If this is not specified for a particular texture, the default set of texture coordinates will be used.
