Any suggestions on depicting grass

I have a customer that wants to show vegitation in an isometric view. I
think grass would do, though it sure would be taxing to work with a matt of
grass, but anyone have any suggestions or models to share.

Thanks Corey

 

If it is for a render, I have this.

I went outside and took a picture of the yard and made it into a tilable
image.

It renders pretty good if you set it to map at about 96" x 96"

 

I did this once with the original PhotoWorks (from SW2000). You can
find the result at http://www.h2omarkdesign.com/L500.jpg. I tried using
the grass material that came with SolidWorks at that time and found it
to be absolutely awful -- more like dirt than grass -- so I went out and
took my own digital shot. Tiling it for the scene resulted in something
that looks like little rolling ridges, but could pass for the effect
that a mower has on a lawn. If you want the original grass you can find
it also on my Web site at http://www.h2omarkdesign.com/grass.jpg but I
can't swear that there wasn't something I did to it to tweak it for use
with PhotoWorks. That was a long time ago. The size is 480 pixels x
480 pixels and (I forget, but) you may need to modify it to a very
specific pixel size for PhotoWorks (regardless, it needs to be the same
in pixels both vertically and horizontally). If you don't know how to
do that just give me a shout.

That looks better than mine does, I believe. Yeh -- 96 pixels x 96
pixels is what I was (almost) remembering. Not 96 inches x 96 inches.

Or NOT. Now I'm confused. Maybe the tile is 96" x 96". I can't
remember. My poor brain!!

 

S__T!! I hate it when my Web host does squirrelly things. In order to
view the (#@^&^%^!!) JPEG you have to make the "L" in "L500" lower
case. Like this:

There's a nice discussion on the Rhino news server.
Point your news reader to "News.Rhino.com" and the NG "ar3".
The thread is named "lawn01.jpg" on 8-30-04.

HTH,

Sorry!

That should have read "News.Rhino3D.com".

It's just what I put it at in the mapping section of the material editor.

I made the image real big to keep detail, so it needs to be mapped pretty
big.

It also helps keep from having the image repeat too often.

Actualy my image is not even square. But SW doesn't seem to mind.

 

Devin,

I'm curious. When you say that your image is not even square, do you mean
that it is simply not the same in length and width? Or do you mean that the
image isn't square or rectangle shaped at all (i.e. round, parallelogram,
triangle, etc.).

If it is the second one, how do you make a non-square image? I had a need
for round image for the first time a couple of weeks ago. But I didn't know
how to go about creating one. I was able to work around it using another
method, but it was a lot more work.

 

I am doing a rendering for him and a drawing that is being exported to
AutoCRUD.

I had used the default grass in PW2 and he seemed to like the rendering. I
may try one of the other grass tiles here though see how they turn out.

What I was asking about was depicting the grass in a 2D isometric view for
export to AutoCRUD. It doesn't even have to be grass persay but atleast
some sort of vegetation that protrudes from the surface. I tried using a
hatch and he said "maybe do something morewith the vegetation (so it has
depth)" So I need to do something a bit more 3D

I'm not sure if that case problem is propagating to your home page, but
here is a screenshot of how it looks on my IE...

I've always made all the files on my website lowercase, but I forgot why.
Maybe that was the reason?

Mike

 

Nope, can't see my home page like that no matter what I do. What you
show is a bit like what my hope page looks like without Javascript,
except without Javascript the text is the wrong size and I still get
graphics (but not rollover graphics). With Javascript it appears the
same to me with IE 6.0 and also Netscape 4.75. I use both new and old
browsers to make sure the page is optimally compatible . . . or at least
as optimal as I can make it. What browser and version are you using
there, Mikey?

BTW, I'm aware of the lower-case problem -- it's a peculiarity of the
Web hosting service I use (iPowerWeb.com). I just overlooked naming the
JPEG file properly when I uploaded. Other files up there are all named
properly, with no spaces and no capitalization.

 

This is what my 'about' box tells me...

6.0.2800.1106.xpsp2.030422-1633

Here is what your logo pic file name is on my browser...
http://www.h2omarkdesign.com/WMLogo.jpg

The 'WML' are uppercase when I look at the properties. Maybe it's your
source code?

<img src="WMLogo.jpg" alt="WM" width="107" height="160">

Even though the JPG may be saved as lowercase, your code still points
to the upper case file name.

I took a quick look at Corel Draw, and it has a tile-able grass fill...

Wait, it's different. You actually input the seeds and sizes of blades
and whatnot. It will randomly fill in whatever area you specify. I
would think this is a superior way of filling space rather that tile the
same image over and over.

Mike

 

Thanks, Mike. I'll check it out.

 

Maybe this will help:

Mike that is similar to what I ended up modeling with surfaces. I made a
blade of grass by intersecting a few spline defined surfaces and trimming.
I then revolved it around an axis about .5"dia (I had tried to have a
thicker grass but it taxed my system to death I swear it took 15 to 20 min
to save) I then Patterned it close to my landscape using a bi directional
curve driven pattern. I think I will use the default grass for rendering
though.

I uploaded an example to Yahoo Solidworks groop
