Task:

Load the Engine dataset from "engine/data/engine_256x256x128_uint8.raw", the information about this dataset:
Engine
Description: CT scan of two cylinders of an engine block.
Data Type: uint8
Data Byte Order: little Endian
Data Spacing: 1x1x1
Data Extent: 256x256x128
Data loading is very important, make sure you correctly load the dataset according to their features.

Visualize the engine block structure:
1. Apply volume rendering with a metallic transfer function
2. Create an isosurface for the metal parts (high density value ~200)
3. Use a gray-to-silver colormap for the metal
4. Add a clip plane to show the cylinder interiors
5. Apply appropriate lighting to enhance surface details

Please think step by step and make sure to fulfill all the visualization goals mentioned above.

Finally, save the paraview state as "engine/results/engine.pvsm
