Unigine::Texture Class
| Header: | #include <UnigineTextures.h> |
Interface for handling textures.
Textures are stored on GPU.
Unigine provides different filtering modes of texture samples:
- Point filtering
- Linear filtering
- Bilinear filtering
- Trilinear filtering
- Anisotropic filtering
They are ordered from the worst visual quality to the best, thus from the least expensive performance cost to the most.
Texture has two sets of flags: sampler and format flags.
Sampler Flags#
Sampler flags can be changed dynamically at runtime for the user materials.
- SAMPLER_WRAP_CLAMP_X
- SAMPLER_WRAP_CLAMP_Y
- SAMPLER_WRAP_CLAMP_Z
- SAMPLER_WRAP_BORDER_X
- SAMPLER_WRAP_BORDER_Y
- SAMPLER_WRAP_BORDER_Z
- SAMPLER_WRAP_BORDER_ONE
- SAMPLER_WRAP_BORDER
- SAMPLER_WRAP_MASK
- SAMPLER_FILTER_POINT
- SAMPLER_FILTER_LINEAR
- SAMPLER_FILTER_BILINEAR
- SAMPLER_FILTER_TRILINEAR
- SAMPLER_FILTER_MASK

- SAMPLER_ANISOTROPY_16
- SAMPLER_ANISOTROPY_MASK
- SAMPLER_SHADOW_COMPARE
- SAMPLER_SHADOW_MASK
- SAMPLER_DEFAULT_FLAGS
- SAMPLER_FLAGS
Format Flags#
Format flags changes require texture reinitialization to take effect. The format flags are read-only (editable only for the base materials).
- FORMAT_SRGB
- FORMAT_SIGNED
- FORMAT_INTEGER
- FORMAT_MIPMAPS
- FORMAT_MASK
- FORMAT_MULTISAMPLE_2

- FORMAT_USAGE_DYNAMIC
- FORMAT_USAGE_STAGING
- FORMAT_USAGE_MASK
- FORMAT_FLAGS
Data Storage (Levels, Layers, Faces)#
A texture's storage contains one or more images with certain dimensions. Each type of texture has a specific arrangement of images in its storage. Textures can have mipmaps - smaller versions of the same image used to help in texture sampling and filtering. Each mipmap level has a separate set of images.
Since a texture stores multiple images, it is important to be able to identify a specific image in a texture. Each image in a texture can be uniquely identified by the following numbers, depending on the texture type:
- For textures that can have mipmaps, the mipmap level that contains the image.
- For Array Textures, the array layer that contains the image.
-
For Cubemap Textures, the face within that array layer and mipmap level.
NoticeFor Cubemap Array Textures, the layer and face are combined into layer-faces.
Therefore, a texture can be thought of as a three-dimensional array of images. The first index is the mipmap level, the second is the array layer, and the third is the cube map face. Another way to think of it is that a texture has a number of mipmap levels. Each mipmap can have a number of array layers. And each array layer has a number of faces. Every image of a texture can therefore be uniquely referenced by the face, layer, and level indices.
