and: just a few examples.)  But did yous know yous tin practice 3-dimensional animations equally well? 

As Thomas Lins Pedersen explains in a recent weblog post, the fob is inward using the persp function to interpret points inward 3-D infinite into a 2-D projection. This role is ordinarily used to homecoming a 3-D scatterplot or wireframe plot, but if yous instead capture its output value, it returns a transformation matrix. You tin together with thus usage the trans3d function to amongst this matrix to transform points inward 3-D space. Thomas demonstrates how yous tin give-up the ghost the transformed 2-D coordinates to plot a 3-D cube, together with fifty-fifty animate it from 2 slightly unlike perspectives to practice a 3-D stereo pair:

Rendering 3-D images isn't but for fun: there's enough of 3-D information to analyze together with visualize, too. Giora Simchoni used R to visualize information from the Carnegie-Mellon Graphics Lab Motion Capture Database. This information repository provides the output of human figures inward motion-capture suits performing actions similar walking, jumping, together with fifty-fifty dancing. Since the motion-capture suits include multiple sensors measured over a time-period, the information structures are quite complex. To brand things simpler, Giora created the mocap package (available on Github) to read these motion information files together with generate 3-D animations to visualize them. For example, here's the output from 2 people performing the Charleston together:
