class | Binding |
A texture has one or more bindings which describe how the different aspects of the texture should be bound in order to allow shader access. More... | |

Represents a texture object in Glf.
A texture is typically defined by reading texture image data from an image file but a texture might also represent an attachment of a draw target.
|
pure virtual |
Returns the bindings to use this texture for the shader resource named identifier.
If samplerId is specified, the bindings returned will use this samplerId for resources which can be sampled.
GLF_API size_t GetContentsID | ( | ) | const |
Returns an identifier that can be used to determine when the contents of this texture (i.e.
its image data) has changed.
The contents of most textures will be immutable for the lifetime of the texture. However, the contents of the texture attachments of a draw target change when the draw target is updated.
|
pure virtual |
Returns the OpenGl texture name for the texture.
GLF_API size_t GetMemoryRequested | ( | ) | const |
Amount of memory the user wishes to allocate to the texture.
GLF_API size_t GetMemoryUsed | ( | ) | const |
Amount of memory used to store the texture.
