This is a model of the Ikea Flimra tumbler drinking glass, including an internal model of liquid, which can be rendered in your choice of materials. Modelled in SolidWorks, including detailed geometry of the internal texture. Rendered in KeyShot, I have included the BIP file in the downloads.
From the Ikea website:
The glass has a simple, low and straight shape which makes it perfect for all types of cold drinks, such as cocktails with ice.sonit
