Hi!

I'm looking for a way to to take some kind of "screenshots". There are however some differences to actual screenshots:
Imagine to have multiple cameras in a world. What I want to to next is to save exactly what they're seeing at one exact point in time - preferably as image.
I had a look at the Camera and Projector classes, but I failed to find anything similar. Before I start implementing this on my own,
I want to make sure that:

• I haven't missed something
• I get some input on how to approach this first

Thank you in advance!

Hi!

I'm currently trying to bring some colors to my virtual worlds by adding textures. But I'm somewhat stuck.
I created a model & texture according to http://www.code5.ch/meckardt/tutorials/wings_textur.html (German)
and exported it as VRML. The exported stuff seems reasonable, even though I didn't check it manually.

The VRML-Spec says, that the TextureCoordinate-Node contains st-coordinates. As far as I know, that differs from uv-coordinates by already being "height-aware".
But I'm not really an expert to this... Anyway, the triangles load fine, and i tried just to push the st-coords along with the vertices into jPCT. Obviously without much success.

I also had a short look at TextureInfo that seems to have a different purpose.

I should add, that I have to load the models myself into a different world model. jPCT pulls the vertices (and...) from there.
This is like this:
Object3D o = new Object3D(..);
o.addTriangle( t.vertices[0], (float)t.vertices[0].u, (float)t.vertices[0].v,
      t.vertices[1], (float)t.vertices[1].u, (float)t.vertices[1].v,
      t.vertices[2], (float)t.vertices[2].u, (float)t.vertices[2].v);

Any help/hint would be great!

PS: I tried to attach a screenshot, but I failed... hard to use these boards ;-)
