animated texture

[gedimaster]

i've been looking into the forum posts but couldn't find much info on animated textures. i'm trying to put together an explosion effect using a series of animated textures but there doesn't seem to be an example available.

can anyone point me to somewhere? thanks.

Render-to-texture is what you are looking for. A search on "RTT" or "render to texture" should turn up quite a few topics. The Wiki should also have RTT info as well.

not really. i'm thinking of animated texture from a series of texture rather than procedurally generating them like in rtt.

say i have a series of 30 textures of a fire animation and i want to run through them like a repeated video on a billboard, how i can do that in ogre? via the material settings?

Look at the DynTex demo.

or alternatively, you can look at ogreaddons/videplugin/TheoraVideo which plays Theora Movies to a texture. A little overkill for this, but, it should also give you ideas.

See texture_anim in the manual. It does exactly that.

Why not just use an animated texture? Check out the manual: http://www.ogre3d.org/docs/manual/manual_18.html#SEC58.

An Example:

Code: Select all

material MyAnimatedTexture
{
  technique
  {
    pass
    {
      texture_unit
      {
        anim_texture frame.png 30 1
      }
    }
  }
}

this will cycle through frame_0.png, frame_1.png, frame_2.png... upto frame_29.png in 1 second. So its animating 30 frames per second.

In Azathoth there is a limit of 32 frames for an animated texture. In Dagon there is no imposed limit.
