  • Need to do a Soccer Ball from the Inside Out!!! Serge?

    Posted by Joseph M. morgan on October 3, 2006 at 2:09 pm

    I need to create a soccer ball such that the camera is inside of it, and light is streaming through the stitching (forget the internal bladder). I can handle the lighting effects with Lux, so no problem there.

    The camera will start from inside the ball and move to the outside, where it will be replaced by a real ball and the reas is easy.

    So I need 2 things.

    1) How do I create the ball as if the camera is inside of it ( from there I can handle moving it to outside the ball, but I do need small gaps in the creases and stitching across the seams, in 3D ).

    2) What’s the best approach. Do I film the real ball and then work “backwards” or simply make the transition from the 3D ball to the real ball as the “camera” passes through the skin?

    First thing’s first, since your referred to Serge in your post, should we propose that you have Zaxwerks Invigorator Pro?

    If you do, you can download a free 3D ball from here (click on the one you prefer).

    So in Zaxwerks you could easily do that “inside out” camera move.

    You could search in the COW’s archives too, we recently talked about how to create a 3D ball without the use of any 3D plug-ins inside of AE.

    Good luck.

    Well, you could use CCSphere with this texture created by Martti Ekstrand https://kashi.hamabe.org/images/football.jpg
    then, set the render for Inside only. Not real 3D, but you can fake it by rotating the Sohere (easier than working with the camera, if you need, duplicate the layer and set the render for outside.

    I hope it helps.

    Hi Joseph,

    Using Invigorator Pro or Classic you should move your object towards the camera until you get inside of your ball.
    If you have the pro version, import a 3D ball as Justin mentioned. Just try to find better ones then in his link unless you have a 3D program to add some polys.
    Also, make sure, in case you are using the object for commercial purposes that you notify the owner.

    [Joseph M. Morgan] “but I do need small gaps in the creases and stitching across the seams, in 3D”

    You could create those gaps using a transparency map in case you are using a completely closed 3D ball or you import the object in a 3D program and make some cuts.
    Let me know what Invigorator version you have and I will help you with that.

    Justin referred to creating a 3D ball with CC-Sphere. Sorry this won’t work for you though as you need to get inside of the sphere. CC sphere can’t do that.
    You could try the render “Inside”/”outside” feature but I don’t think this could work in your case.

    Salut.

    Yes, I have Zax 4 Pro.

    I think my newbie ness will show now…Are those soccer balls zax balls in aep files? If not, how do I use them?

    Serge, thanks for the reply. I have Zax 4 Pro. I don’t have Lux yet, but will have to get it for this project to create the volumetric lighting coming from “outside” the ball. (Read that to mean this gives me a good excuse to get Lux :-))

    The “sunlight” that is seeping in through the seams of the ball will actually be illuminating objects within the ball.

    Then the camera moves out through the skin of the ball… at this point, the camera will blur it where I can replace with an actual ball I’ll have on film.

    The transparency map, I would think, would need to be the polygons of a soccer ball. I think I have the idea there, so that I will try.

    The stitching has me stumped.

    The texture with CC-Sphere looks OK, but, I don’t see how to get inside of the ball. Even redering just the inside still makes it appear as if I’m standing outside the ball. I increased the radius, but still no luck.
    What am I missing?

    Try applying effect>distortion>optics compensation to the same layer (after CC sphere), set to a high FOV with reverse distortion checked.

    Hi,

    [Joseph M. Morgan] “The stitching has me stumped.”

    I could better help if knew how you created your ball. Did you use a map or a 3D object?

    If you are using a texture map, make sure you change the black soccer parts to white then use this new map as a transparency map.

    If you get stuck let me know.

    [Joseph M. Morgan] “Are those soccer balls zax balls in aep files? If not, how do I use them?”

    Do you mean the InvigoMany balls? If so then, Yes. All you would need to do is open the aep and animate your soccerball. It is made out of single faces so moving the elements apart will open the stiches easily.

    Salut.

    OK… This is where I am (still playing with ideas). I created a 3D primitive sphere in Zax. I downloaded the soccer ball texture for the suggestion in CC Sphere, and applied that as a transparency map. That creates the breaks in the polygons just fine, but it also hollows out the pentagons of the ball. So, I suspect I’ll just change the texture for the transparency to turn the black spots white, leaving just the seams black. The should work just fine.

    How to I put on a texture map? I don’t see that option? I think that is my answer, because the ball looks fine with the transparency map, but, of course, I don’t have white/black areas from the inside.

    I can make a nice bump map to make the ball look more natural, and I’ll tweak it from there.

    I got it. Thanks for all your quick help. Now to figure out the camera… but I can handle that.
