A helper class for accessing data in a slice of a volume.

protected |
NOTE: This is provided for the purpose of taking a snapshot of current status of a VolumeSlice, which will then be used for rendering. The copy constructor shouldn't connect to any signals so its state won't be changed after construction. NOTE: The copy-constructed object will share the same texture object with the old one.
| void Core::VolumeSlice::move_slice_to | ( | double | depth, |
| bool | fail_safe = false |
||
| ) |
Move the slice to the specified depth in world space. Returns true if the slice is moved successfully, otherwise false.
|
pure virtual |
Upload the volume slice to texture. NOTE: This function allocates resources on the GPU, so the caller should acquire a lock on the RenderResources before calling this function.
Implemented in Core::MaskVolumeSlice, Core::DataVolumeSlice, and Core::LargeVolumeSlice.
| void Core::VolumeSlice::world_to_index | ( | double | i_pos, |
| double | j_pos, | ||
| int & | i, | ||
| int & | j | ||
| ) | const |
Get the index of the point that's closest to the given position in world space NOTE: the indices returned can be out of the slice boundary.
