 ## Object and Scenes
 
 The dataset includes 50 objects categorised into four groups based on their complexity, material composition, and shape:
-- `single-material_convex/`(18 scenes): Objects with convex geometries, each composed of a single refractive material, such as transparent cubes, balls, and pyramids.
-- `single-material_non-convex/`(40 scenes): Objects with non-convex geometries, each composed of a single refractive material, such as animal sculptures, glass jars, light bulbs, candle holders, and magnifiers.
-- `multiple-materials_non-convex/`(42 scenes): Objects with non-convex geometries, each composed of multiple refractive materials or a combination of refractive and opaque materials, such as reed diffusers, a glass of wine, and flasks filled with chemical liquid.
+- `single-convex/`(18 scenes): Objects with convex geometries, each composed of a single refractive material, such as transparent cubes, balls, and pyramids.
+- `single-non-convex/`(40 scenes): Objects with non-convex geometries, each composed of a single refractive material, such as animal sculptures, glass jars, light bulbs, candle holders, and magnifiers.
+- `multiple-non-convex/`(42 scenes): Objects with non-convex geometries, each composed of multiple refractive materials or a combination of refractive and opaque materials, such as reed diffusers, a glass of wine, and flasks filled with chemical liquid.
 
 Each object is placed in two distinct scenes:
 - `textured_cube_scene/`: Objects placed within a bounded textured cube environment.
