Descripción

Class for handling Sparse Textures.

Sparse Textures son texturas dónde no toda la información de texturas puede ser presentada en la memoria de una. Ellas también son comúnmente llamadas "tiled textures" o "mega textures".

Imagínese una textura 16384x16384 en 32 bits por píxel - tomaría 1GB de memoria. La textura es rota en "tiles" rectangulares, y cada baldosa(tile) puede estar presente en la memoria o no. Usted puede cargar y descargar estas baldosas(tiles) como sea necesario basado en la distancia desde la cámara, sectores del mundo que el jugador tiene que ver, etc.

De otra manera, las sparse texturas se comportan como cualquier otra textura en sombreadores - ellas pueden tener mimaps, pueden utilizar todos los modos de filtración de textura, etc. Si a usted le toca leer de una baldosa que no está presente, usted puede obtener un resultado indefinido (en la mayoría de GPUs el resultado es un color negro, pero eso no es garantizado).

Not all hardware and platforms support sparse textures, so you should check SystemInfo.supportsSparseTextures before using them. For example, on DirectX systems they require DX11.2 (Windows 8.1) and a fairly recent GPU; and on OpenGL they require ARB_sparse_texture extension support. Sparse textures only support non-compressed texture formats.

After creating the sparse texture, query the tile size with tileWidth & tileHeight. Tile sizes are platform and GPU dependent.

Use UpdateTile or UpdateTileRaw to make a tile resident in memory and update its color data. Use UnloadTile to unload a tile.

Variables Estáticas

allowThreadedTextureCreationAllow texture creation to occur on any thread (rather than the dedicated render thread).
currentTextureMemoryThe amount of memory currently being used by textures.
desiredTextureMemoryThis amount of texture memory would be used before the texture streaming budget is applied.
GenerateAllMipsCan be used with texture constructors that take a mip count to indicate that all mips should be generated. The value of this field is -1.
nonStreamingTextureCountNumber of non-streaming textures.
nonStreamingTextureMemoryTotal amount of memory being used by non-streaming textures.
streamingMipmapUploadCountHow many times has a texture been uploaded due to texture mipmap streaming.
streamingRendererCountNumber of renderers registered with the texture streaming system.
streamingTextureCountNumber of streaming textures.
streamingTextureDiscardUnusedMipsForce the streaming texture system to discard all unused mipmaps immediately, rather than caching them until the texture memory budget is exceeded.
streamingTextureForceLoadAllForce streaming textures to load all mipmap levels.
streamingTextureLoadingCountNumber of streaming textures with mipmaps currently loading.
streamingTexturePendingLoadCountNumber of streaming textures with outstanding mipmaps to be loaded.
targetTextureMemoryThe amount of memory used by textures after the mipmap streaming and budget are applied and loading is complete.
totalTextureMemoryThe total amount of memory that would be used by all textures at mipmap level 0.

Variables

hideFlagsShould the object be hidden, saved with the Scene or modifiable by the user?
nameEl nombre del objeto.
anisoLevelNivel de filtrado anisotrópico de la textura.
dimensionDimensionalidad (tipo) de la textura (lectura solamente).
filterModeModo de filtrado de la textura.
graphicsFormatReturns the GraphicsFormat format or color format of a texture object.
heightAltura de la textura en pixels. (Read Only)
imageContentsHashThe hash value of the Texture.
isReadableReturns true if the Read/Write Enabled checkbox was checked when the texture was imported; otherwise returns false. For a dynamic Texture created from script, always returns true. For additional information, see TextureImporter.isReadable.
