Detailed Description

Defines the properties of a named stage of the multitexture pipeline.

The TextureAttrib will associated a number of these stages with Texture objects, and the GSG will render geometry by sorting all of the currently active TextureStages in order and then issuing the appropriate rendering calls to activate them.

◆ set_saved_result()

void TextureStage::set_saved_result ( bool  saved_result)
inline

Sets the saved_result flag.

When this is true, the output of this stage will 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.

◆ set_sort()

void TextureStage::set_sort ( int  sort)
inline

Changes the order in which the texture associated with this stage is rendered relative to the other texture stages.

When geometry is rendered with multiple textures, the textures are rendered in order from the lowest sort number to the highest sort number.

Also see set_priority(), which is used to select the most important textures for rendering when some must be omitted because of hardware limitations.

◆ set_tex_view_offset()

void TextureStage::set_tex_view_offset ( int  tex_view_offset)
inline

Sets the tex_view_offset value.

This is used only when a special multiview texture is bound to the TextureStage, and it selects the particular view of the texture that is to be used.

This value is added to the similar parameter on DisplayRegion to derive the final texture view index that is selected for rendering.

◆ set_texcoord_name() [1/2]

void TextureStage::set_texcoord_name ( InternalName *  name)
inline

Indicate which set of UV's this texture stage will use.

Geometry may have any number of associated UV sets, each of which must have a unique name.
