##### Thickening surfaces ... too complicated?
« on: March 09, 2011, 01:04:43 am »
Hello all:
Someone with some experience in getting a surface or solid  at a given distance from a surface/ 3dfaces ?

Greetings.

Are you using MESHEXTRUDE?

The following prompts are displayed.

Mesh face(s) to extrude
Specifies the mesh faces to extrude. Click one or more faces to select them.

Height of extrusion
Direction
Path
Taper angle

Hello
It's a good idea, but sometimes I have the 3DFACE so that I can not easily make a mesh that contains them faithfully.

Hello to the people of the swamp:
I think I have one solution ...¿!?
Generating points on the faces normal to the desired distance and then generating a triangulation mesh based in

with all the new points. I think it will work as long as the surface does not have many cavities. I hope.

Hello to the people of the swamp:
It is necessary to follow the path opened by the great masters.
Paul Bourke's routine is perfect for areas without convexity. And very fast.
She generates some small triangles on the edges of the contour.

But looking for a blatantly tilted normal can locate and eliminate these ghost triangles.
Another thing is to do a very professional program to do it automatically so perfect.

Hello:
It opens up many possibilities ... such entities on a project various irregular field.
A photo? A logo on the grass of a sports field?

One could calculate the perspective from the point of view of a television camera to give the feeling flat image, being on an uneven surface?

Hello Cab
Thanks but is only a little work and much Euclidean geometry.
The previous dwg has a small problem of coordinates Z ( steps ).
I think in the new is resolved.
Please , put the view "OK" and active / desactive the layer "FOTO"....It is surprising ?
Do you find interesting? Why would it serve?
Greetings.

I'm one of those nerds that finds that stuff fun.    I like it when people post this problems to The Third Dimension section   Gives me an excuse to play.
Hello everyone
You just play and also you make toys?
