1. A computer-implemented method for blending at least two three-dimensional volumetric structures, the computer-implemented method comprising: associating, via a processor, a first primary color and a first translucency to a first dataset sourced from a medical scanner, and a second primary color and a second translucency to a second dataset sourced from the medical scanner, each of the first dataset and the second dataset having a respective three-dimensional surface representation of a mammalian anatomical structure, the first primary color is visually distinct from the second primary color, the medical scanner captured the first dataset and the second dataset at different times; assigning, via the processor, a color coding scheme to a set of distance differential values, the color coding scheme having a continuous color range, the set of distance differential values is associated with the first dataset and the second dataset; shading, via the processor, a surface of a three-dimensional surface representation associated with at least one of the first dataset or the second dataset on a display based on the color coding scheme that corresponds to the set of distance differential values; and blending, via the processor, the first and second datasets by visualizing, via the processor, the translucent surfaces of the first and second datasets on the display to produce, via the processor, a blended, volumetric, and interactive representation of the first and second translucent surface datasets simultaneously on the display as the mammalian anatomical structure, the blended representation is depicted in a secondary color as blended from the first primary color based on the first translucency and the second primary color based on the second translucency such that an improvement or deterioration difference of the mammalian anatomical structure between the different times is visually noticeable and such that the set of distance differential values is set to the color coding scheme and is modified based on at least one of rotating or panning the blended representation while the opacity of the blended representation is changing, the processor is in communication with the display.
