What is the most cross-browser/system compatible option for 3d graphics on a web page?

I would like to develop a bit of functionality for a web site that involves a bit of 3D - the user can move around objects, rotate them and texture them. So far I've looked into: WebGL (in particular three.js) and it looks great, but it's not…

Rendering trillions of "atoms" instead of polygons?

I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited…

My algorithm that extracts the largest box that can be made from smaller boxes, is too slow

Imagine a cube based world (such as Minecraft, Trove, or Cube World) where everything is made up of identically sized cubes and all the cubes are of the same kind. The goal is to represent the world with the fewest number of rectangular boxes (by…

Data structure for determining intersection between line and polygon in 3D

I have a collection of non-self-overlapping simple polygons P. In actuality, they are 2D triangles in 3D-space. I'm looking for a data structure which, given a line L, has a relatively fast lookup for all polygons p in P which L intersects with. If…

Detecting surface faces of a huge 3D mesh/grid

I've written a module in my application that creates a mesh from existing coordinate and face data. The number of vertices in the mesh could easily exceed 10 million and the same goes for the faces. The problem with the raw data is that the faces…

Using a “spherical frustum” for 3D projection

I am currently writing a transformation from model space to clip space for use in OpenGL. From what i have seen, programmers typically use a traditional rectangular frustum to define the clipping boundaries in their model space. I personally had in…

What's the HTML5 3D canvas? How is it different with WebGL?

I heard about 3D canvas. It's strange for me. Because I know there's already a industrial standard 3D API WebGL. What's that? How is it different with WebGL?

How to create a T-shirt or book displacement map in practice?

So I learned that the feature I am interested in is called a "displacement map". This makes it so you can take a blank t-shirt (with all it's curves and subtle textures), and apply an image to it so it looks like the t-shirt actually has that image…
