Unigine::Texture Class
| Header: | #include <UnigineTextures.h> |
Interface for texture manipulation.
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 worst visual quality to the best thus from least expensive performance cost to the most.
