Perspective view

 

 

Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life. Several different, and often specialized, rendering methods have been developed. These range from the distinctly non-realistic wireframe rendering through polygon-based rendering, to more advanced techniques such as: scanline rendering, ray tracing, or radiosity. Rendering may take from fractions of a second to days for a single image/frame. In general, different methods are better suited for either photo-realistic rendering, or real-time rendering.

Anaglyph images

 


Anaglyph 3D is the name given to the stereoscopic 3D effect achieved by means of encoding each eye‘s image using filters of different (usually chromatically opposite) colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the „color-coded“ „anaglyph glasses“, each of the two images reaches the eye it‘s intended for, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into perception of a three-dimensional scene or composition.

Stereoscopic images

 


Stereoscopic images present two views of the same scenery with a different perspective for each eye next to each other. These images and videos can be watched using 3D capable screens, virtual reality glasses, and – ingeniously simple – with a self-assembled Google Cardboard and a smart phone.
