## ◆ setCpuData()

void nkGraphics::Texture::setCpuData | ( | const ResourceCpuDataDescriptor & | data | ) |

Sets the CPU data from which the texture should load when the load() method is called. Data needs to be formatted for the format specified for the texture.

If multiple sub-resources are needed but left unspecified (_subresources member left empty), their location and size will be automatically determined. In such case, it is expected that they fit the DirectX ordering :

- Each 2D texture entry is directly followed by their respective mip chain
- For an array of textures, each entry fits the first rule and follows the last one
- No padding is applied, data is considered tightly fitting

To give an idea of what is expected, the data for a 2D 2x2x6 texture array would be in this order :

Tex0 Mip0, Tex0 Mip1, Tex1 Mip0, Tex1 Mip1...

In case the sub resources are specified within the provided descriptor, the data description is entirely left to the user. This means that if there are holes in the description, they won't be filled automatically.

Parameters

  data | The texture data to feed from the cpu to the texture.

Remarks
  Data needs to remain available while the data loads. For cleaning the memory, see the freeCpuData() function that will ensure data is available as long as required.

## ◆ addCpuDataSlice()

void nkGraphics::Texture::addCpuDataSlice | ( | const nkMemory::BufferView<> & | data,
|  | unsigned int | byteOffset = `0u`,
|  | unsigned int | rowByteSize = `0u`,
|  | unsigned int | sliceByteSize = `0u`
| ) |  |

Adds a CPU data slice from which the texture should load when the load() method is called. This method will only create a view over provided data.

A slice can be a mip, a texture array entry, or a 3D texture slice. Pixel data needs to be formatted for the format specified for the texture, each channel at their given position. For instance, R8G8B8 would need a char buffer with bytes interpreted as RGBRGBRGB...

Multiple slices (mips, entries...) can be provided with consecutive calls to any variant of the function. They should be made in the right order for the texture to interpret data correctly. The expected input order depends on the texture nature, but should fit the DirectX ordering :

- Each 2D texture entry is directly followed by their respective mip chain
- For an array of textures, each texture entry fits the first rule and follows the last given slice given

To give an idea of what is expected, data for a 2x2 texture would be in this order :

Mip0, Mip1

Data for a 2D 2x2x3 texture array would be in this order :

Tex0 Mip0, Tex0 Mip1, Tex1 Mip0, Tex1 Mip1, Tex2 Mip0, Tex2 Mip1

In the case a texture expects multiple slices, but only one is given through these functions, missing slices will be reconstructed within given buffer if its size allows it. Else, they will be set to black.
However, this behaviour is only true for 2D textures. Currently, texture arrays and 3D texture need to have all their slices declared upfront if data is provided.

Parameters

  data | The texture data to feed from the cpu to the texture.
  byteOffset | The offset, in bytes, at which slice data starts in buffer.
  rowByteSize | The size of a row, in bytes. Leave it to 0 to have it derived from the texture's width and its pixel format byte size.
  sliceByteSize | The size of the slice, in bytes. Leave it to 0 to have it derived from the row size and the texture's height.

Remarks
  Source data needs to remain available until the texture is fully loaded (getLoadState() returning RESOURCE_LOAD_STATE::LOADED).

## ◆ addCpuDataSliceCopy()

void nkGraphics::Texture::addCpuDataSliceCopy | ( | const nkMemory::BufferView<> & | data,
|  | unsigned int | byteOffset = `0u`,
|  | unsigned int | rowByteSize = `0u`,
|  | unsigned int | sliceByteSize = `0u`
| ) |  |

Adds a slice declaration, with data that will be copied to an internally managed buffer. See addCpuDataSlice() for more details.

Parameters

  data | Data to provide to populate the slice.
  byteOffset | The offset, in bytes, at which slice data starts in buffer.
  rowByteSize | The size of a row, in bytes. Leave it to 0 to have it derived from the texture's width and its pixel format byte size.
  sliceByteSize | The size of the slice, in bytes. Leave it to 0 to have it derived from the row size and the texture's height.

Remarks
  This variant will copy data into an internally managed buffer, making the memory footprint higher. As such, source data can be erased right after. Once unnecessary, it will be required to call freeCpuData() to free newly created internal data.

## ◆ addCpuDataSliceForward()

void nkGraphics::Texture::addCpuDataSliceForward | ( | nkMemory::Buffer && | data,
|  | unsigned int | byteOffset = `0u`,
|  | unsigned int | rowByteSize = `0u`,
|  | unsigned int | sliceByteSize = `0u`
| ) |  |

Adds a slice declaration, with data that will be forwarded to an internally managed buffer. See addCpuDataSlice() for more details.

Parameters

  data | Data to provide to populate the slice.
  byteOffset | The offset, in bytes, at which slice data starts in buffer.
  rowByteSize | The size of a row, in bytes. Leave it to 0 to have it derived from the texture's width and its pixel format byte size.
  sliceByteSize | The size of the slice, in bytes. Leave it to 0 to have it derived from the row size and the texture's height.

Remarks
  This variant will invalidate input data as it is moved around into the internally managed buffer. Once unnecessary, it will be required to call freeCpuData() to free it.

## ◆ addCpuDataSliceRelativeToLast()

void nkGraphics::Texture::addCpuDataSliceRelativeToLast | ( | unsigned int | byteOffset = `0u`,
|  | unsigned int | rowByteSize = `0u`,
|  | unsigned int | sliceByteSize = `0u`
| ) |  |

Adds a slice declaration, relative to last slice provided. This variant will reuse the last valid memory buffer provided and finds its spot inside depending on given parameters.

Parameters

  byteOffset | The offset, in bytes, at which slice data starts in buffer. Leave it to 0 to have it directly starting after last slice's byte size.
  rowByteSize | The size of a row, in bytes. Leave it to 0 to have it derived from the texture's width and its pixel format byte size.
  sliceByteSize | The size of the slice, in bytes. Leave it to 0 to have it derived from the row size and the texture's height.

Remarks
  This function requires another slice to have been set before, with a valid buffer, so that it can be expressed relatively to it. It is perfectly valid to define many slices in a row using it, as all parameters will be derived, if required, relative to the last.

## ◆ setBackBufferTex()

void nkGraphics::Texture::setBackBufferTex | ( | bool | value | ) |

Parameters

  value | If the texture is the back buffer, aka the final texture, of a RenderContext.

Remarks
  In theory, should not be called by external code. Used by the parent RenderContext.

## ◆ setFromImage()

void nkGraphics::Texture::setFromImage | ( | const nkImages::ImageView & | image | ) |

Sets the texture to load from a given pre-decoded image. This will translate all required metadata and data to be interpreted by the texture during loading. For best performances, it is advised to provide images fulfilling these conditions :

- RGB format that can be interpreted directly : R8G8B8A8, B8G8R8A8, R16G16B16A16, R32G32B32, R32G32B32A32
- Or compressed format that can be interpreted directly : BC1, BC2, BC3, BC4, BC5
- If image has a 1 byte per channel format (R8G8B8, B8G8R8, Y8U8V8_444) then one pixel needs to have a size of 4 bytes. This can be achieved at parsing time by either asking a pixel alignment of 4, or adding an alpha channel.

Failure in doing so will trigger an internal conversion, resulting in a copy and more processing, to make the image compatible.
Note that YUV formats will be re-interpreted as RGB formats, directly using the Y as R, the U as G, and the V as B. If you need it properly converted, it needs to be done upfront.

Parameters

  image | The image to use as input.

Remarks
  The image data is not copied for the texture to use it, unless internal conversions or realignments have to happen. For safety, cpu data created internally will be pointing to the memory from the image view provided. Be sure to keep this data available until the texture is fully loaded (getLoadState() returning RESOURCE_LOAD_STATE::LOADED).

## ◆ setFromImageCopy()

void nkGraphics::Texture::setFromImageCopy | ( | const nkImages::ImageView & | image | ) |

Sets the texture to load from a given pre-decoded image, by copying provided data. For more details, please refer to setFromImage().

Parameters

  image | The image to use as input.

Remarks
  This variant copies the image provided into an internally managed image. As such, it is not necessary to keep source image around during texture loading. However, the memory footprint is higher. It might be beneficial to call freeCpuData() as soon as possible after the call to load(), if data won't be needed anymore.

## ◆ setFromImageForward()

void nkGraphics::Texture::setFromImageForward | ( | nkImages::Image && | image | ) |

Sets the texture to load from a given pre-decoded image, by forwarding provided data. For more details, please refer to setFromImage().

Parameters

  image | The image to use as input.

Remarks
  This variant forwards provided image to an internally managed image. As such, input data will be emptied as memory is moved around. If necessary, to free internal data, a call to freeCpuData() will be needed after the call to load().

## ◆ freeCpuData()

virtual void nkGraphics::Texture::freeCpuData | ( |  | ) |
| virtual

Frees the cpu data attached to the texture, possibly with the internal buffers if the texture owns them. This function has to be called after the load method has been called, for the process to know when the data can be fred.

## ◆ setGammaCorrected()

virtual void nkGraphics::Texture::setGammaCorrected | ( | bool | value | ) |
| virtual

Parameters

  value | If the texture should be gamma corrected (true) or not (false).

Remarks
  Gamma correction acts on the format of the texture to leverage the GPU's automatic correction when available. To be sure this functionality will work when enabling the flag, a compatible format should be used. Compatible formats can be found within the nkGraphics::FORMAT enumeration, as compatible formats have an SRGB alternative. Other formats won't be able to be gamma corrected and will trigger a warning if it is requested or left to the default true value. In such case, you can turn off the flag to avoid the warning, and manually correct the colour within the nkGraphics::Program code. Another alternative would be to convert the texture to a supported format.

## ◆ setPath()

virtual void nkGraphics::Texture::setPath | ( | nkMemory::StringView | value | ) |
| override virtual

Sets the resource's path, relative to the working directory. See nkResources::ResourceManager for path naming conventions.

## ◆ setMipLevels()

virtual void nkGraphics::Texture::setMipLevels | ( | unsigned int | value | ) |
| pure virtual

Parameters

  value | The number of mips wanted for the texture. Can be 0 to mean that all mips should be used.

Remarks

| pure virtual

Parameters

  format | The format to assign to the texture.

## ◆ setCpuAccessRights()

virtual void nkGraphics::Texture::setCpuAccessRights | ( | BUFFER_CPU_ACCESS_FLAG | rights | ) |
| pure virtual

Parameters

| pure virtual

Parameters

  usage | The texture usage.

## ◆ setTextureBinding()

Parameters

  other | The texture to copy the information from.

## ◆ setTextureFormatFromString()

void nkGraphics::Texture::setTextureFormatFromString | ( | nkMemory::StringView | str | ) |

Parameters

  str | The string defining the format to use. StructToString will be used for translation.

## ◆ setMightManuallyGenerateMip()

void nkGraphics::Texture::setMightManuallyGenerateMip | ( | bool | value | ) |

Sets whether the texture should expect to get requests to generate its mip chain during its lifetime, or not.

Parameters

  value | Whether the mip generation calls are to be expected (true) or not (false.

Remarks
  This flag is off by default For more details, see generateMipChain(). It is advised to turn this flag on only when necessary, as it forces the loading process to declare broader usages to the graphics API.

## ◆ prepareAsTexture2d()

virtual void nkGraphics::Texture::prepareAsTexture2d | ( |  | ) |
| virtual

Prepares the texture as a 2d texture. Should be used to change the internal texture type, impacting the way the texture will be loaded.

## ◆ prepareAsCubemap()

| virtual

Prepares the texture as a cubemap. Should be used to change the internal texture type, impacting the way the texture will be loaded.

## ◆ prepareAsTexture3d()

| virtual

Prepares the texture as a 3d texture. Should be used to change the internal texture type, impacting the way the texture will be loaded.

## ◆ setRenderFlag()

## ◆ generateMipChain()

virtual void nkGraphics::Texture::generateMipChain | ( | unsigned int | fromMip = `0` | ) |
| pure virtual

Request to generate the texture's mip chain, for available mip levels. This requires the texture to already be loaded.

Parameters

  fromMip | The mip level from which the mip chain generation should start.

Remarks
  Calling this method requires the correspondig flag to be enabled before the texture is loaded (see setMightManuallyGenerateMip()).

## ◆ convertToImage()

nkImages::Image nkGraphics::Texture::convertToImage | ( | int | mip,
|  | int | sliceOrArrayIndex
| ) |  |

Allows to access the data of a texture in a practical way, through an image.

Parameters

  mip | The mip level from which the data should be accessed.
  sliceOrArrayIndex | The slice, or index in the array, to take the memory from.

Returns
  The data found in the texture for queried parameters, abstracted behind an image class.

Remarks
  This will trigger a map of the image before copying the data into the user-friendly structure. If you need more performances or limit memory usage, it will probably be best to use the standard map() method, albeit more cumbersome to use.

## ◆ map()

virtual MapResult nkGraphics::Texture::map | ( | const MapRequestDescriptor & | requestDesc | ) |
| pure virtual

Maps the texture memory for CPU interaction. Be sure to select the smallest map type needed, as a map operation can cause a flush in the rendering pipeline.

Parameters

## ◆ unmap()

virtual void nkGraphics::Texture::unmap | ( | const UnmapRequestDescriptor & | requestDesc | ) |
| pure virtual

Unmap the texture memory. This needs to be called the earliest possible after a map operation. This operation will potentially commit the changes made in mapped data, to the GPU.

  descriptor | The description of the data to copy.

Remarks
  This function copies GPU memory to GPU memory.

## ◆ exportClassToTree()

virtual void nkGraphics::Texture::exportClassToTree | ( | nkExport::Node * | rootNode | ) |
| override virtual

Exports an item into a tree describing its structure and its data.

Parameters

  rootNode | The node into which the object has to write its related information.
