  2. Oil sands - Wikipedia

    en.wikipedia.org/wiki/Oil_sands

    The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, a heavy and viscous form of petroleum, in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market. [27]

    The Melville Island oil sands are a large deposit of oil sands (sometimes referred to as tar sands) on Melville Island in the Canadian Arctic Archipelago. [ 1 ] [ 2 ] Exploration for petroleum deposits in the Canadian Arctic Archipelago began, on Melville Island, in 1961. [ 3 ]

  4. Tar pit - Wikipedia

    en.wikipedia.org/wiki/Tar_pit

    This is the only reported instance of human remains found within tar pits. [25] For thousands of years, Native Americans used tar from the La Brea Tar Pits as an adhesive and binding agent. [1] They would use it as waterproof caulking to line their boats and baskets.

    Oil sands, often pejoratively referred to as tar sands, are a phenomenon unique to the tundra environment and are profitable and plentiful in the Athabasca region of the Alberta sands. [16] Oil sands consist of bitumen, which contains petroleum, found in a natural state combined with clays, sands, and water. [ 16 ]

  7. 3D computer graphics - Wikipedia

    en.wikipedia.org/wiki/3D_computer_graphics

    3-D computer graphics rely on many of the same algorithms as 2-D computer vector graphics in the wire-frame model and 2-D computer raster graphics in the final rendered display. In computer graphics software, 2-D applications may use 3-D techniques to achieve effects such as lighting, and similarly, 3-D may use some 2-D rendering techniques.
