using " @gen xfade" to crossfade geometry on 2

    Jul 24 2013 | 12:58 pm
    Hi everyone
    If I put two to @matrix out 1 and send them both to a jit.xfade i can morph between one model to another (same amount of verts,edges,faces). If I try to do it " @gen xfade" nothing happens. What is it I'm missing ??
    Any and all tips welcome.

      It may be related to the number of planes coming out from the only supports 4-plane matrices. You should try using [jit.gen @gen xfade] instead
    • Jul 24 2013 | 7:43 pm is intended to be used with 4 plane texture data (as mentioned above). outputs geometry data, not texture data, and so should be used with jit.gen.
      check out the "Appendix B: The OpenGL Matrix Format" section of the reference docs for more info on the geometry matrix format.

      Thanks Lska ! Missed that one ! Rob, I tried it with jit.gen @gen xfade but still no joy , I've plugged it into and then into a videoplane. I'm still a noob with Gen but should I maybe use jit.unpack on both models and fade the values together with Gen, or will this not give me an advantage with CPU compared to just using the standard jit.xfade ?

      slab and videoplane are related to textures.
      you should send your matrix to a instead
      here's a simple example:
      but the helpfile is much more detailed (have a look at the last tab...)

      Finally nailed it ! Thanks Lska ! just slipped under my radar. I'm going to try and make 5 models which can all be crossfaded together into one model. Time to dig into Gen :)
