In fact, three dimensional rendering often times also uses methods such as vector-based modelling and bitmap file type texture generation, both of which originated in two dimensional rendering methods. However, this is not to say that both three dimensional and two dimensional renderings utilize entirely distinct rendering methods or the characteristics of these rendering methods. While three dimensional computer imaging uses much the same software, algorithms and techniques as two dimensional rendering, certain visual effects can only truly be applied to the aforementioned three dimensional renders, owing to the distinct nature of the three dimensional models used in a 3D scene and the visual implications that come with them. Three dimensional rendering, on the other hand, are renderings produced through computer graphical generation that mimic or replicate that of real life visual effects, with factors like multiple perspectives, animation and even photorealistic lighting all being hallmarks of quality three dimensional rendering work. This is especially so when two dimensional renderings are subjected to post-production effects, such as the use of photo manipulation software to mask any errors missed by the artist or to overcome current technological limitations. While it is entirely possible to produce a two dimensional rendered frame from a three dimensional scene, it is often far less efficient and is most usually done as a proof of work concept or for use in examples provided to a client.Īsides from these factors, two dimensional rendering may also be differentiated from other forms of rendering by which the modelled or rendered assets present in the scene are created, with the relatively restricted point of view used in two dimensional rendering allowing the artist to use hand-drawn images or those taken with a camera in real life with very little noticeable difference. These effects are more often seen in three dimensional rendering products owing to the fact that they “trace” a line of light between three dimensional objects present in the rendering scene, something that is otherwise not possible in two dimensional renderings because of a lack of three dimensional space at which to bounce the light through. This means it cannot otherwise be rotated or viewed from an alternative angle without rendering it once more from this new perspective, essentially locking the audience into a single view of the scene.Īpart from this restriction in the angle at which the rendering is viewed, there is also the case of particular rendering techniques that are utilized, especially in concern to light subsurface scattering, reflective surfaces and light ray penetration or diffusion. Two dimensional rendering, otherwise abbreviated to 2D rendering, is an end-product form of computer graphical generation wherein the point of view of which the image is seen from is static or otherwise stationary.
