Hi, I try to run Libmini on Linux and I am using the data that I prepared using VTP running on Windows, however it crashes in miniOGL.cpp at line 678; ...
Hi Murat,    I ran into the same problem. It appears that GL_COMPRESSED_RGB_S3TC_DXT1_EXT isn't supported in Mesa (the OpenGL library that comes with...
... As an alternative you might be able to get it work, if you are ready to install packages / set environment variables which might have problems with...
Hi Murat and Kirsten, some thoughts about Mesa and S3TC: "S3TC support is available for Mesa, but not fully or cleanly. Pre- compressed S3TC textures can be...
It's been a few years since I've built VTP, so I'm looking for recommendations on my build environment. I'm following the "Building VTP on Windows" page and...
Hi, I have problems with animations: + Speed in m/s is much bigger than real (perhaps 30X). + Saving animation as image sequence, setting time 1 s for each...
Alberto, Which version of Enviro and operation system are you using? I'm using v1.11 (retrieved from SVN on Oct 17th) on Windows XP. I've confirmed the frames...
Hi Brent, Thanks for reply. VTP version is the 1.1 110804 of August on Windows XP pro in a desktop with3GB ram and NVidia Quadro FX 3500 (256MBram): I have had...
When I follow the tutorial (http://vterrain.org/Doc/Tut4/) VTBuilder crashes when doing the "Merge and Resample Imagery". I t crashes in vtImage::SetRGB,...
... I wouldn't care too much about the potentially out-dated comment. The problem is that compressed textures can't be merged into a compressed texture....
Stefan, Many thanks for the reply. I've set aside the texture image problem for now and I'm looking at the elevation data. It seems VTBuilder loads the...
Stefan, I tried using 32-bit VTBuilder on 64-bit Windows 7 with the same result: it stopped loading after about 20 GDEM files (I thought the 2gb address space...
Stefan, See my comments below. Thanks! Best Regards, Brent Fraser ... No. VTBuilder attempts to load all the DEM data into memory and fails. I haven't tried...
Stefan, I was able to get libGrid's gridder to output a paged tileset, but VTP couldn't deal with a db type of extformat=3 (DATABUF_EXTFMT_Z?). I think that's...
Hi Brent, ... Fixed that. Please try again with the latest libGrid source from svn. You can specify the option "compress"; which enables s3tc compression ...
Stefan, Many thanks for the update. With the new changes I was able to create a Paged Tileset with gridder that loaded in Enviro using the Sample data...
... Thanks for the hint, I am going to fix that soon. libMini just ignores that line and takes care of the gcs by itself. ... Same with that. @Ben: On the...
Hi, I have two terrain data of same area with different textures, when I start terrain rendering at a location I can switch from one terrain to another at the...
Stefan, One issue that may cause problems in the future is too many files in a single folder. Dunno about Linux, but with Windows is can be a real performance...
Hi everyone, I am building my first model in vtp. It includes about 150 buildings plus some roads and trees. It runs quite smoothly in Enviro, but all the...

Hello Mario, I think the problem you describe could depend to Enviro "Camera-View" settings. Please, test to change "Near Clipping Plane" and "Far Clipping...

Hi Mario Two other possibilities: 1. If the building is too far from the origin it can cause flickering (even with a transform) . This is a common...
Hi guys The changes in the clipping plane values didn't take any effect on the flickering issue. By the way, the buildings are not imported from other...
Hello again, In my previous posts I didn't express myself correctly. The problem I'm having with the textures is not flickering but aliasing (I think...). From...

Mario, could you insert a small full resolution video on YouTube about this problem (and send the link to vtp-list)? BobMaX ... [Non-text portions of this...
... Did you check if mipmaps are enabled, both in Enviro settings and in your graphic card settings? You can try increasing the level of antialiasing in your...
Hi, mipmaps are enabled in the graphics card. The enviro global settings are: texture compression: checked disable model mipmaps: unchecked The antialiasing in...
... It should be ok... anyway the description of your problem indicates a not proper use of mipmaps from Enviro. I don't know if it's a problem of your graphic...
