Video and 3D animation

Video is the technology that allows the creation of movement by viewing a succession of computer-generated still images. Photorealistic digital animation is used to render a video of an unbuilt work, as well as to simulate images that cannot be generated by other procedures. Within the world of digital animation and its applications, the production of digital animation and video games, architecture, graphic design and 3D animation, engineering or industry stands out. Other applications of computer-generated animated infographics are the creation of digital animation and visual effects in movies or the simulation of scientific data. 2D and 3D digital animation is created from computer programs that generate a series of frames that are then modified and played back in a video. Advances have now been made in real-time simulation producing great results in terms of image quality and richness of detail.

The video rendering process begins with the choice of the keyframes within the architectural spaces that you want to include in the video or animated infographic, the location of the camera within the scene and how this camera is going to move. You can also make the sound track and post the video. The process of creating the intermediate frames to create the movement between the keyframes is called interpolation. There are numerous techniques that allow software to generate intermediate frames from calculating the camera position between key frames. The computer creates the camera movement between two keyframes by interpolating the distance between them and dividing the path into the required number of frames. Animated 3D models can also be inserted into a scene, such as moving people or vehicles or tree branches moving when the wind blows. When a sufficient number of images have been generated, smooth and continuous movement is achieved. In real-time online animated infographics, the frames are generated by the software and immediately reproduced on the computer screen. With this it is possible to eliminate the digitization phase of the images.

Once all the frames have been generated, a video can be made by playing them in order. The video infographic digitizes each scene frame by frame and finally the video of the final animated infographic is produced. Generally, it is the software that generates the 3D video render as a final result without the need to obtain the frames as an intermediate process, although it is also possible to obtain them if necessary, such as if the video is to be post-produced later. Advances in photorealistic digital animation technology have made the digital animation and interactive design production process more realistic, detailed, and faster than it was in the beginning.

In order to reproduce the video we need a computer device and a software or application capable of reproducing it. Currently we can play videos on a multitude of devices such as televisions, computers, tablets or mobiles. The emergence of virtual reality has brought many advantages, such as watching 360-degree VR videos or 360-degree VR images on specific devices for augmented reality such as virtual reality helmets or glasses. But at the same time, the evolution in virtual reality applications and 360 degree videos has also made it no longer essential to have a virtual reality device to play one of these videos, since VR videos can be played on PC or VR videos for mobile phones have software installed to play these videos.
