2D stands for “two-dimensional”. The term 2D animation refers to the process of creating two-dimensional images that are shown in sequences to create the feeling of motion. Methods to create a 2D animations are traditional animation and vector-based computer animation.
2,5D (also known as three-quarter perspective or pseudo-3D) is a term referring to the variety of 2D animation techniques used to create images and scenes that look as if they are appearing in three-dimensional space, although they are really not. One of the most common ways to create 2,5D perspective is by using parallax effect.
3D stands for “three-dimensional”. The term 3D modeling stands for the process of creating three-dimensional objects, that will be moved in virtual three-dimensional space in the process of 3D animation. 3D animation processes and models are, by far, mostly used in gaming and film industry, but they are also quite common in visual presentations, commercials, explainer videos etc.
Unlike digital cinema resolutions, that used and are still using the horizontal dimension to specify the resolution (see 4K and 8K definitions), TV resolutions, until the appearance of terms 4K and 8K, used the vertical dimension for this purpose. That is why full HD resolution is commonly called 1080p, referring to 1080 pixels in height, namely the resolution of 1,920×1,080 pixels.
Short for 4K resolution (also known as 4K UHD), 4K is a term that stands for a horizontal screen display resolution of 4,000 pixels. When speaking about theater projectors, 4K stands for a horizontal resolution of 4,096 pixels; however, it is also very common to refer to Ultra HD (UHD) TV resolution as to 4K resolution as well (although the exact UHD TV resolution is actually 3,840x2160px, not full 4,000 pixels in width).
short for 8K resolution (also known as 8K UHD), is a term referring to the currently highest ultra high definition resolution in digital television (7,680×4,320 pixels).
360-degree videos (also known as immersive videos or spherical videos) are recordings which allow the viewer to observe their content from every viewing angle and direction. 360 videos can be recorded either by using an appropriate, so-called omnidirectional camera, or several cameras strategically placed to film an object or an event from many different angles.360-degree videos (also known as immersive videos and spherical videos) are recordings which allow the viewer to observe their content from every viewing angle and direction. 360 videos can be recorded either by using an appropriate, omnidirectional camera, or several cameras strategically placed to film an object or an event from many different angles.
