    3d Objects

    I have heard you can load your own 3d objects into catalyst and map images or movies onto them like the cubs and the wonderful Tea Pot. However I am unsure what type of 3d object file Cat Requires and how to do this since I can't find any info on this subject. Can anyone be of help?

    Cheers

    Catalyst 4.02 + does support 3d obj models.

    Create a folder called 'Models' in the same folder as the application.
    Name your model files using 3 digit numbers like movie files.

    000Model1XXX.obj
    001Model2YYY.obj

    etc...

    Restart the application

    Richard,

    As promised, I can create a whole bunch of useful OBJ 3d models for you. I think I would include about 200 of them all consisting of slightly incrementing and different degrees of curved planes both in NTSC and PAL, horizontally and vertically. I would also create a bunch of other awekward surface types such as corners and collumns so that video could be played on very skewed surfaces.

    This would aid tremendously in projecting on curved screens. Previously you could only bend a screen on a very slight angle but with these curved planes, one would be able to project on a much more curved screen. This would open up a lot of possibilities for projection.

    Just let me know if OBJ is the format you need them in. Otherwise let me know what format would serve you best. Any additional requests for 3d projection models come through Richard please.

    Thanks,

    Christian

    The release version of catalyst 4 is advertised with:

    Ability to import 3-D images (.obj)

    But I can find no mention in the preliminary manual as to how to do this beyond:

    Catalyst V4 can accept files created in Quartz Composer and 3-D .obj files.

    after you install or put the software in a folder you just open the package and navigate to models then drop yous in there.

    The models have to be huge so I would open one up to get an idea,

    I think I see why this is undocumented!! I don't think hacking at the package resource level was what the High End sales literature had in mind!

    Anyway, I've got a good looking half a meg of humanoid, who looks quite funky with some suitable lurid color fx applied whirling about.



    Thanks

    I think it's a brilliant implementation being able to use models to straighten out non planar geometry that you want to be able to project on. There have been many instances when production designers have come to me wanting to be able to project on non planar or curved projection screens and it's always been a bain because I couldn't before. This option really adds to the funtionality of Catalyst.

    A really easy to use and great piece of software that is MAC compatible and creates .OBJ models is Modo 202. It's very very intuitive and you can create anything from very simple models to extremely complex ones in a fraction of the time it takes to model in Maya. It costs around $695 or $895.

    XSI foundation for PC or linux only is also a great modeler, animator, shader, and widely used overal 3d package for only $495.

    Most studios are migrating to XSI 6 foundation for most of their front end work and then importing the models via XSI crosstalk technology into Houdini or Maya to light and shade via Renderman plugs.

    If you ust want to be able to easily create models without animating them and need an easy to learn package that works within Mac, I would purchase Modo. If you want a more full featured package that allows you to do everything from dynamics, modeling, shading, Rigging, and rendering I would purchase XSI foundation, that is if you don't mind working with it in a PC environment.

    Cheers.

    It is worth checking out Hexagon 2 at Daz 3d. Only $149 and a good intuitive modeler.

    Works hand in hand with Carrara 5 which does animation also.

    Back to importing an .obj file, I have done all the steps and can't get it to appear in the visual effects control. Does anyone have a sample .obj file they can post so I can try? I have been trying with files found on the net, and that may be the problem. Any help would be appreciated
