View Full Version : Wireframe transition to fully textured

Can anyone help me with this?

I want to put a shot together of a camera sweeping along a ship at sea with everything textured except the ship which is wireframe, but as the camera sweeps along the hull, the ship becomes textured just ahead of the camera.

The way I hav considered doing this - but before I render it all I would like some idea if it is going to work :) - is to rende the full sequence with everything textured, and then render the same sequence with everything textured except the ship, then composite the sequences together in RedGL.

Is this the most efficient way of doing it?

If this works, I might detail the sequence more, with shots of the sails being textured after the hull etc etc.

Thanks,

Martin

Hi Martin!,

I think the way you describe (rendering twice & fading later) would be the most usefull, especially because then you can have 'realtime control'. If the rendertimes really matter, you could try to plan your transition very good, so that you only render the wire-ship for instance on frame 1 to frame 150, and the textured one from frame 130 to 250 (so that you can get a translation of max 20 frames ;) )

Otherwise you could think of building an animated material (in Max for instance just with a 'mix' on top of 2 mats?! :) ), and animate the transition in your 3D app itselfs. I myself wouldn't like to do that: I always like it better to to such things in post, as control of the final result is very important...! :)

Is it meant for a demoreel or for a sort of a documentary? Or something different? ;)
Let me know if it was usefull & please show us the result when finished... :buttrock:

Greetz,

Yeah I think I'll render various sequences and mix them together in post.

It's actually for the opening sequence of a CG film - but the point of the film is that it's obviously CG (although photorealistic - if that paradox makes sense!), so we want to hit the audience with that from the word go.

I think I'm going to do the hull in the first sweep, then cut to a shot of the ship from above ("seagull view" :) ) and texture the decks and buildings, then cut to another shot sweeping back down the ship and do the masts. That's 6 renders then (3 shots) which I will then post-mix down.

The ship is in rough seas with lightning and storm clouds too, so this could take a couple of weeks! :) Will post WIP as and when.
