... Yes, that's right; Actually what I want to get is the region of the terrain which is in the view frustum. I use : vtHeightFieldGrid3d *pHeight =...
Has anyone created and viewed a Terrain with a 4x4 tiled dimension of 16381 (base tile size of 4096) or larger? I've created one but it crashes wxEnviro on a...
Hi Brent Yes, I have tried that with the same results using a similiar computer configuration. It seems that the current limit is 8189 (2048 base tile). ...
Fredrik, Is this due to a limitation in the graphic card or to a limitation/bug in Envro? FYI, I just tried it with a 256 mb ATI card with the same result ...
Brent, I have tried many configurations also with the same results and I think it's a limitation in Enviro. Ben should know, I'll guess he will comment on this...
Ben and all, I'm a freshman of vtp, and I dont know too much about its opensource software, but I have a lot of inerests in it. I have read some articles about...
Hello everyone, I heard there have been updates to the Project and would like to download the updates. Unfortunately I misplaced the site address to download...
Hi Alex The realtime quality of the VTP tools can be excellent, and very bad. It's the same as asking an artist if a pen and paper are good tools. It all...
Fedrik-- Not to go off topic but I took a look at your site - excellent grabs! In particular, nice tree models. Out of curiosity, are yours open source,...

Thanks Ben Most of the trees is our own proprietary trees photographed in Sweden, but we also use some tree images that comes with 3D Natures Visual Nature...
Dear Fredrik-- How unfortunate (still - gratz on the renderings, they look great). If anyone can recommend a good source for open source tree models, that ...

Hi Ben W. have you checked out procedural generators such as: http://www.onyxtree.com/broadleaf.html whilst not opensource they might sponsor Ph.D. research by...

Hello VTP Users Sorry, I dont remember exactly the tools names (I searched some years ago for a mapper tools to do plants and trees, was quake3-mapper), so I...

Hi Yaming, ... Well, you're talking about the intersection of the frustum (a truncated pyramid) with the heightfield (where elevation can vary freely). The...
Yaming, I wrote one response on the VTP mailing list, but i want to be sure that you ... The intersection is only approximately a trapezoid in very specific ...
... Ben, the only known open source tree models are those in the VTP Plant Library, which you are already familiar with. The response from Peter Morse and...
Dear Ben D. and the other members of the VTP Community-- Just a suggestion but the VTP library remains scarce in its range of species. There is, for example,...

... What might be even easier is to shoot a ray from the camera and see where it intersects the terrain (there is a function for this). You could also work out...
... Since I've used all the software listed here at some point or another (and in the case of some, still do...), I thought I'd add a few points. ... I own a...
... Adam, thanks for the software reviews, it's useful to have a more detailed impression than the links and brief summaries on the VTP site. Naturally, all...
Adam-- Thanks, this is really good. In past discusions Ben D. has briefed me on many of these products. But it is always good to get additional input. I...

You are right about that link, Ben... I do not know when it was taken offline (or rather bought for use by another company) I have done some searching, and...
Brent, There is no hard-coded limit to texture size in Enviro/vtlib. The limits are the RAM and driver of your graphics card. Consider that a 16k*16k texture...
I think this is appropriate, given the recent questions about such things. This is the same library that is included with 3D Nature's WCS/VNS products. 13195...
Ben, Well, I thought I would try. My calculations were: 1. 24-bit texture size = 768 mb Convert to: 2. 16-bit = 512 mb Use texture compression: 3. 512 / 4 =...
... Yeah, that's a familiar story. I remember back in the mid-90s in the VR industry, a constant comment from the public was, "why isn't your software as fast...
