Hi,

    I encountered few problem would appreciate if someone could answer.

1). Is there a way to retrieve information about the adjacent vertex in
vertex shader?

2). The water waves are created by translating heightmaps in waterdemo2,
upon closing looking, you could see the waves aren't translating smoothly
because color values are discrete. This is the shader code
" ...
vec2 Texcord = texCoord + waveInput.time*10.0 ;
position_object.y += texture2D(texHeight, Texcord/128).r * 2.0;
..."
Is there are way to like interpolate the values between two consecutive
colors to make waves go smoother?

2). How do we add texture to the inner side of a box generated like this
"...
  CS::Geometry::DensityTextureMapper mapper (0.3f);
  CS::Geometry::TesselatedBox box (csVector3 (0, 0, 0), csVector3 (10, 10,
10));
  box.SetLevel (3);
  box.SetMapper (&mapper);
  box.SetFlags (CS::Geometry::Primitives::CS_PRIMBOX_INSIDE);

  // Now we make a factory and a mesh at once.
  csRef<iMeshWrapper> walls =
CS::Geometry::GeneralMeshBuilder::CreateFactoryAndMesh (
  engine, room, "walls", "walls_factory", &box);
..."

I'm trying to make a skybox.


Also, Could someone get the search functionality working on the
documentation given in the link "
http://www.crystalspace3d.org/docs/online/manual/"?
