Folks,

Say I have a logo of a company that is in 2d i.e. in .jpg or .tga.
And they want to make the logo 3d, so that it can spin have shadows cast onto to it etc.

What would be the best way to do that ? Would I have to edit a box so that it got into the shape that I wanted and then to import the .jpg image ?

Or could I simply type out the text in Houdini and then be able to extrude the text so that it was in a 3d image ?

Thanks in advance for your help.

Cheers

hey starkhorn

a quick solution could be The Trace sop, with the jpg or tiff, to convert ur 2d image into something that houdini sops can work with.

Then a poly extrude,
then a primitive sop to with the face/hull vertex set to reverse.
poly cap for the open end
finally a facet sop to fix the normals, tick cusp poly's and post compute normals.

it all depends how intricate ur logo is,
if its just text (then u could use the font sop) or if its a shape that u'd have to model - i'd start with a a plane that has a UVquickshade of ur image applied, to give u a reference in houdini to model from,
then normally a box using alot of poly split's to add detail and an edit sop to shape the logo. (when poly splitting, try keep ur faces 4 sided which is better for subdividing the geom right at the end.)


hope this helps

all the best

couple other things to add on to that:

first check out www.brandsoftheworld.com and see if your company happens to be there. they have an extensive collection of worldwide company logos in beautiful vector format. be a lot better than jps and could probably import it as a spline into Houdini..

or if that fails.. put your jpg in the back of one of the 2d viewports (right, top, left, etc).. and draw a spline(s) around it to recreate the logo. Use that spline(s) as a base to extrude from and woalla, you have your 3d logo..

thanks guys. Both good ideas. Not too sure of arcaids stuff to be honest….a little beyond me at present

but the spline idea looks something that I can manage……ok now I'm off to read the docs to learn what a spline does….

hey starkhorn

just to help u out, the trace sop bascially “traces an image for contrast”, so it would outline detail in an image.
its really easy to use and actaully quiet impressive.
so even if u dont use it, check it out, its a nice sop to know about.


anyways

hope u come right
