The triangular tiling visible (through IE/ASV and Opera9.2.3) at http://srufaculty.sru.edu/david.dailey/svg/triangles4.svg is created with script: a pair of tightly nestled equilateral triangles has been put in a group that is then cloned across the visible region.
Odd and even numbered triangles are filled with different gradients (mainly since if the fy attribute of the gradient is not tweaked then the center of the gradient defaults to the center of the bounding rectangle which is rather different than the perceptual center of the triangle).* I sought to try simplifying things by building the tiling it with <pattern> rather script. I think any periodic tiling of the plance can be simulated with a rectangular pattern. To simulate the two adjacent equilateral triangles, I split one of them into two halves -- both right triangles -- and appended these halves on either side of the whole one. The pseudo-triangles tile just fine, as can be seen at http://srufaculty.sru.edu/david.dailey/svg/triangles5.svg ** The problem is that I can find no way to fill the adjacent half-triangles with what would appear to be a shared radial gradient -- even by adjusting the horizontal offset "fx" of the gradients of each. If they share the same radial gradient, then that gradient appears centered relative to the bounding box of each half-triangle individually. What I want to do is to create something identical to http://srufaculty.sru.edu/david.dailey/svg/triangles4.svg but with <pattern> instead of DOM. My thought is that it oughta be faster -- but who knows? maybe it won't be. Any insights on the relative speeds of such things? Any ideas? TIA, David *The gradient is (of course) animated with SMIL (shouldn't gradients always be animated?) and has its stop-color rotated through JavaScript with synchrony between the SMIL and JavaScript being handled by "begin='indefinite' onend='animate()' " in the SMIL and animatedObject.beginElement() in the script (without the synchrony, the two animations tend to diverge in ways that, while not unpleasant, are a bit chaotic. ** Incidentally, I think the fact that IE/ASV changes the size of the pattern space, making little edges appear at times during the SMIL, is probably a bug in ASV. Opera doesn't do it.
