Oct 8, 2018 · For 3D Geometry: I have developed a free 3d drawing program that runs in modern browsers (html5). The English version is called Geoservant 3D, the original German version is called Geoknecht 3D. There you can specify 3d shapes (solid geometry) and animate them by changing their values.

Mar 22, 2011 · After you specified some 3d shapes you can also animate their properties by changing the number values. See description on page how to change values: holding down ALT key and using cursor keys. Also have a look at the gallery on the page to see what things you can achieve with this program. It also calculates basic values of the 3d objects.

Mar 25, 2021 · I have tried reading on it however got conflicting information. There are some sources that say that 3D objects don't have a perimeter. It's only applicable to 2D objects. However in other sources I have seen people trying to calculate perimeter of a cube(3D) by measuring the length of each connecting line and adding them up.

Jan 27, 2022 · One common way to represent 3D shapes is by using implicit equations. ... and then the 3D object is the ...

Feb 16, 2023 · How can I optimally get the list of vertices for the 3d shape (a convex hull) formed by a set of intersecting planes in 3d space that contains all feasible solutions. Assuming that a 3d shape is formed by the intersection of the planes? Is there a name for the problem space/algorithm I'm seeking for? My background in this area is not very strong.

Sep 18, 2019 · The general idea is to pick your favourite 3D rotation, represented as a $3\times3$ linear transformation matrix, then cut out the top $2\times2$ submatrix and use that as a 2D linear transformation. Example: Rotation around the Z axis by angle $\alpha$. The $3\times3$ matrix corresponding to this rotation looks like this:

Apr 5, 2015 · $\begingroup$ Aha, never thought about doing the same-side-check with the triangle vertices and the planes. I am somewhat unfamiliar with some of these concepts though - can you expand on what you mean with "Now, compute the intersection (a two dimensional problem, the intersection is a segment determined by the intersection of the intersection of the …
