How/What to use to make a 3D sitemap

Tag: 3d,three.js,sitemap

.Hello, I am trying to create a more interesting sitemap for a page I am currently updating. The company that owns the site is huge (the page they use has 50+ individual departments, each with sub-departments etc) so I was wanting to make a visual representation of all the pages in the site to help people look around for the right department, sub-department, or sub-sub-etc. department.

Ideally the user would either be able to use a search in the top corner of the page where all matches on the map are highlighted and then be able to click on the link as well as see the path to that page via the map. Additionally each of the very top departments should extend, from the center, on a different z axis to allow the maximum amount of information to be displayed while still being as organized as possible.

I am happy to learn whatever language or libraries would be needed, I'm just at a loss as to where to even begin. I thought about Three JS as I've heard and read about how amazing it is for 3D images but I do not see an obvious example of its use that I could ply to this attempt (if you have any please put it as an answer).

TLDR - I'm trying to build a 3D sitemap but do not know what to learn to make it, please advise.

Thank you for any input!

Find affine transform M that translates this ellipse in axis-oriented one (translation by -p and rotation to align orientation vector r and proper coordinate axis). Then apply this transform to point p and check that p' lies inside axis-oriented ellipsoid, i.e. x^2/a^2+ y^2/b^2+z^2/c^2 <= 1

Three js, block textures are blured

javascript,web,three.js

First of all you are loading the same texture several times. So assign it to a variable and then make the textures resolution-independent and render without blurriness. var border_tex = new THREE.ImageUtils.loadTexture('img/texture/herbe/border.gif'); border_tex.magFilter = THREE.NearestFilter; border_tex.minFilter = THREE.LinearMipMapLinearFilter; var top_tex = new THREE.ImageUtils.loadTexture('img/texture/herbe/top.gif'); top_tex.magFilter = THREE.NearestFilter; top_tex.minFilter = THREE.LinearMipMapLinearFilter; var...

Stripped shadows on collada objects

You are getting self-shadowing because the rays of the directional light are exactly parallel to some of the faces of your geometry. Move the directional light to a slightly different location.

EdgesHelper loses its mesh when scene is rotated

three.js

Yes, this is a consequence of how EdgesHelper(and some of the other helpers) have been implemented. If you want to use EdgesHelper, you have to adhere to two rules: EdgesHelper must be added to the scene, directly. The scene can't have a transform applied (for example, be rotated). Consequently, you...

Pygame 3D: How to and is it possible?

python,performance,dictionary,3d,pygame

Pygame doesn't have the ability to do this natively. If you really want this, you'll need to brush up on your trigonometry to map lines from the 3D space to the 2D screen. At that point, you'll essentially be re-implementing a 3D engine.

Updating a material's texture map with images rapidly (every 50ms or so) causes huge stuttering

I supose, since you store the canvases in an array, you don't...

Understand Vectors use

In three.js, the Vector3 class can be interpreted as representing either a 3D point, or a 3D direction vector emanating from the origin. Be careful, though. Direction vectors, when used as arguments in three.js methods, are assumed to be normalized -- that is, of unit length. three.js has a method...

What does three.js's Matrix4.multiply() method do?

javascript,matrix,three.js,linear-algebra,matrix-multiplication

The problem is in how you're iterating the matrix elements to print them. The .elements property returns the elements in column-major order (despite the constructor and .set() methods parameters being in row-major order!). So you should: function logMatrix(matrix) { var e = matrix.elements; var $output = $('#output'); $output.html(e[0] + '...
