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

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 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.

'Sporky'

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, Muggs

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 m>> That looks better than mine does, I believe. Yeh -- 96 pixels x 96

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

Argh. That's going to be difficult. The only idea coming to mind is to get a digital picture of grass from the right angle, and see what it looks like after using edge detection on it. I don't really expect that to convey the appearance of grass though.

Perhaps make a block of a single tuft of grass, then insert several dozen of them at varying scale factors to create a foreshortening effect.

That's all the ideas I have.

This might go faster with overlapping hatch areas with different scales.

I mean that it's not the same width and height. It is a rectangle.

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 host>

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

Here is what your logo pic file name is on my browser...

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

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

Mike

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

Mike Wilson

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.
