A number of mathematically defined surfaces has been easily produced with BlendLink and are on sale at Turbosquid. What could be of general interest (and can be used directly on top of Sverchok and Blendbridge) is the BlendLink addonīlendLink enables user to define quite easily a parametric (and parametrized) surface with user defined per vertex color or You may calculate the length of a vector v using length sqrt (v v) or length Length (v) You can get the coordinates of the starting and terminal point of a vector v. Adjust the range of values for which t is plotted. Use functions sin (), cos (), tan (), exp (), ln (), abs (). Example: You can create the midpoint M of two points A and B by entering M (A + B) / 2 into the Input Bar. Edit the functions of t in the input boxes above for x and y. Here are some figures, read on after them.Ĥ46008 446007 In GeoGebra, you can also do calculations with points and vectors. Surfaces coming out of this are on sale on Turbosquid for fundraising (Google for Turbosquid Twingsister to find them) but actually you can download BlendBridge and addons (helping fundraising with just one offer) and build all of them. On top of it we built a number of couple of plugins, Quadrics and ColorQuadrics to explore the possibility of this approach. You can enter a line in parametric form thus: g: X (1, 6, 3) + (7, -4. Then, you can enter the equation h: y mx + b to get a line h in y-intercept-form. You can enter a line in parametric form thus: g: X (-5, 5) + t (4, -3) Define the parameters m 2 and b -1. You simply need to install this (together with Sverchok, possibly) to enjoy the other addons provided by TWINGSISTER. Drag the points that control the parametric equations x (t), y (t), and z (t) and observe how the 3D curve (x (t), y (t), z (t) changes. Type in g: 3x + 4y 2 to enter line g as a linear equation. Both work best if the Sverchok addon is installed, too.īlendBridge is a library that enables user to build easily Blender addons to add parametric surfaces. Basically you will find a set of Blender addons, notably BlendBridge and BlendLink. Google for TWINGSISTER and Sourceforge and find out. We banged out some bunch of code for this. Demo: Animated GIF / multi-page PDF export with ExportImage() Activity.
