llSetTextureAnim() on the Wiki

I redid the page, 'cause to be honest, it was incomprehensible and in a lot of spots, wrong.

Anyone feel like taking a look to see if I made any glaring errors?

I'd modify the page to implement my suggestions, but I lost my password and haven't been able to get it reset.

"The SMOOTH flag will cause the animation to scroll between the frames instead of jumping frame-by-frame. The frames will still be played in the normal sequence, however."

It might be useful to note that this is pretty ineffective with a y_frames of greater than 1.

The part on ROTATE is useful... the old page was a mess, and I had no idea how to use this until I experimented with it.

looks good to me.

I like the 'only one animation can be run per prim' on the first line
handy that.

but I mean who'd be so daft as to try and run multiple animations on a single prim anyway

Really? I was basically going through testing all the different options for the function, and SMOOTH appeared to work fine for a 6x6 texture animation. Oh... unless you mean there aren't many uses for a texture animation script that smooth-scrolls across every row of a y_frames > 1 animation... which I suppose is true.

I have found one use for SMOOTH animation with y_frames >1: smooth animation on a twisted torus or tube with planar mapping. For some reason planar mapping results in high texture repeat. Setting x_frames and y_frames to about 10 causes the smooth animated texture to have a reasonable scale.

i can think of many reasons, altho its all special efects and fluff hehe

Well, what I meant was that when it gets to the end of row 1, the start of row 1 repeats off the right side, and then it flips down to row two, so you get a sudden break... I mean, it might have its uses, but it's not as useful as it could be It makes sense why this happens, though, given how texture anims are done with repeats and offsets.

Oh! Good point, Lex. Heh, I actually never noticed it did that until you pointed it out.

Another reason that one might want to use y_frames > 1 with SMOOTH animation is if you want to combine several animation loops into one texture. Just as builders often like to have an object use different subsets of a common texture on different prim faces. Each prim would use the same texture with a different start and all would use a length of 1. Of course, this also works with y_frames = 1 and x_frames > 1.

To elaborate on my previous post: I rezzed a 10mx10mx10m tube with 90deg start and end twist and set the texture mapping to planar (and set the hole size to <1.0, 0.05>. Then I animated the texture and counted the tiling. Planar prims faces have a tiling of about 40x40, instead of the 1x1 tiling seen with default texture mapping. Using x_frames > 1 and y_frames > 1 is the only way that I can see to demultiply the tiling under planar mapping. The end result is a 19.5m diameter circular pool.

Thanks for the wiki update. The lSetTextureAnim() page is now much more clear.
