LordCrash interpolation is term used in maths and computing for calculating or generating values in between other known values. if you have a sequence of numbers like 0, 2, 4 you can interpolate intermediate values to get smaller/smoother increments (eg 0, 1, 2, 3, 4). in the context of vr porn it means frame interpolation.. which is converting a video with a low frame rate (30 fps) to a higher frame rate (60 fps) by generating intermediate frames.
