Putting graphics on a wall
Another newbie...
I am using AC3D to model a trade show exhibit booth, and so far it is going extremely well. The booth will have large wall graphics (12' x 6') on a smooth wall. I have created samples of these in Photoshop, saved as .jpg. What would be the best way to stick these to the wall in my model? What I have been doing is creating a rectangle, then applying the .jpg as a texture and then putting that rectangle real close to the wall. I get a lot of bleed-through or something (diagonal lines) and have to pull the rectangle away from the wall. Looks a little goofy. Any ideas? Thanks, Robert Robinson |

Putting graphics on a wall
Use tiffs if it on paper.
If on a screen .jpg should work, giffs are better however. |

Yes putting one object next to another will do that.
I will try to describe simply a way of doing it ... using a very simple model ... but it should give you the idea With snap to grid on.... Assuming the wall is a rectangle ... in vertex mode hi-lite the vertices that define it ... and then from top menu: Surface---> Make hole Now hi-lite all the vertices that define the hole : Vertex--->Snap to grid Vertex--->Create Convex Surface If you view the hirarchy a new object has been created ... it will not have a name. Put your poster on this new object (Adjust the vertices of the new object AND the hole as necessary for your poster. If the wall has a texture on it (bricks say) then texture will be messed up, and you will need to use the texture editor to remap it properly Hope that helps griff |

Thanks very much for this. Cutting a hole in the wall and then placing the poster in that hole does eliminate the diagonals.
Any ideas about how to do this on a curved surface? Some of the walls in the exhibit booth are curved and will also have large posters (text and images) on them. Thanks again for your help. Robert |

You can cut square holes in the side of a cylinder using the Knife plugin.

I have not tried using Dennnis's Knife plugin ... but I'm sure it will work fine.
There are several ways I use to do the kind of thing you want. Technique below is one I use to put labels on bottles (for example). I'm making the assumption the curved surface is like a column but technique will work on all types of curved surfaces too. 1. Create an ellipse (16 points works well for a column). 2. Extrude the ellipse 4 times (deleting orginal surface as you go). 3. In vertex mode, hilite the vertices that describe four surfaces in centre of the object (see the pic below wireframe on left) 4. Now Surface--->Cut away Object. (End result is solid object on right coloured to show the two objects you now have). 5. Apply your poster texture to the new object (red one). If curvature of wall is large you may have to tweak the texture in the texture editor, or if really large use UVMapper to map it to a cylinder. Tweak the spacing between each extrusion to get your poster fitting properly . You can repeat the cutouts around the pillar at essentially 90 degree intervals ... so you could have 4 posters on a pillar. Hope that helps, griff |
