Why 3D-animation ? Key feature of 3D-animation is flexibility.
To make a 3D-animation, the virtual objects in a 3D-scene are given a life of their own and the camera records this in a picture-sequence; a movie.
No gravity exists in a 3D-scene, so objects can move without limits. Since a virtual camera does not have the physical limitations of a real-world camera, its motion is completely unrestricted.
After evaluating an initial preview of the animation, it is possible to make any required changes. The motion of individual objects can be fine-tuned or even completely changed. Lighting setup and material properties can be adapted. Just imagine the hassle and cost of reshooting real camera footage.... Please view the animation below explaining the advantages of 3D-animation.
Why 3D-visualization ? Key feature of 3D-visualization is flexibility.
A 3D-scene consists of virtual objects, light sources and a camera. Material properties like color, texture, glossiness, reflection and transparency are assigned to each 3D-object. Virtual light sources illuminate them. Then the virtual camera is ready to take a digital picture. The required image dimension is set along with other parameters. This is called 3D-rendering.
After evaluating an initial preview the objects can easily be moved, rotated and scaled. Material properties can be adapted, the camera placed in any position and zoomed in or out, until the picture is perfect for the visual you have in mind. Just imagine the hassle and cost of reshooting real pictures in a photo studio....... Please view the animation below explaining the 3D-visualization process.
