In terms of another way to do DEM using <replicate> that is a lot faster, when the associated contour can be easily described by curves, take a look at
http://srufaculty.sru.edu/david.dailey/svg/text/replicatePath4.svg It uses only 10 lines of markup, including one <ellipse> one <animate> tag and a <replicate> with a couple of <replicatePath> to simultaneous vary three attributes of one curve based on the two-dimensional input. The animation runs fairly fast in Opera, IE/ASV and FF4, though webKit doesn’t seem to handle it. Few DEM’s would be reducible to such simple curves though, as this terrain is “extruded” from the dark red curve shown in the drawing. cheers David From: svg-developers@yahoogroups.com [mailto:svg-developers@yahoogroups.com] On Behalf Of mikh2161 Sent: Wednesday, June 15, 2011 9:51 PM To: svg-developers@yahoogroups.com Subject: Re: ïÔ×ÅÔ: [svg-developers] Bitmap gradient What is the speed like? I want to use it for an animation, so I need it to be able to cycle through the colors quickly. That's why I think bitmap DEMs would be faster. Here's an example using using a bitmap and minus the color cycling: http://isometricland.com/svg/kaleidoscope_flame.svg Mike --- In svg-developers@yahoogroups.com <mailto:svg-developers%40yahoogroups.com> , Andrew Matseevsky <a_matseevsky@...> wrote: > > > > š > > > > I have some DEMs I've embedded in an SVG file.
