jlongster / dom3d Goto Github PK

Hello James,

I am new to your dom3d API.
I have seen the examples, the teapot and the pole.
I am wondering if it is possible to zoom in/out with dom3d and if it is possible to identify a unique 3d triangle when pointing to it with the mouse pointer ?

Hi,

I'd like to suggest you use DocumentFragment in the CSS renderer to add all the elements in bulk, not one at a time. This will greatly improve performance.

See John Resig's article:
http://ejohn.org/blog/dom-documentfragments/

I think you can get rid of seams using borders.

Obviously, not by setting all four of them but by always only any two out of four adjacent borders, and eventually none (see example below).

Your algorhithm might figure out...

1. what color to give
   • calculated from mean of the colors resulting from the gradients of adjacent triangles
2. which borders to draw
   • based on an adjacent triangle's existing borders
   • based on the visibility of a triangle
     • if the other side is invisible, obviously the color is the same as that of the face

...and gone are the seams.

Example

Consider a basic four faced pyramid: the last face won't need any borders as they are already produced by the other three since there are 4 triangles, 3 edges each, thus 12 edges, however only 6 edges needing a border.

No -o- love?
