    Blender interstitial volume : a novel virtual measurement of structural complexity applicable to marine benthic habitats
    (Elsevier, 2019) Sadchatheeswara, Saachi; Moloney, Coleen L.; Branch, George M.; Robinson, Tamara B.
    Blender interstitial volume is a novel method that utilizes 3D modeling techniques to accurately and efficiently quantify the volume of interstitial gaps in marine benthic habitats, as well as the space provided by substrate rugosity. This method builds upon the analog methods routinely used on rocky shores and intertidal habitats, including those that measure rugosity, topography, fractals and volume. The method provides a direct Euclidean measurement and uniquely allows retrospective analysis if historical data on species composition are available. Blender interstitial volume allows users to quickly build and measure a large number of samples at no extra cost. The program for Blender is free and opensource, and requires no extra equipment Once 3D models of species are made, the entire method takes less than ten minutes to complete Blender interstitial volume is as accurate as Fractal analysis in determining structural complexity on rocky shores, but is more consistent and precise, and better at discerning differences
