Hello
everybody:
I
know that this is not really a Java3D API question, but
anyways...
I´m looking for one or some ways of providing to a 3D surface with a map
texture.
Nowadays I read from a DTED format map, map coordinates and their relative
height. With this information I'm creating a 3D surface that represents the zone
of the map with this surface (mountains, etc.). I´m using TriangleStripArray for
making the map in line sections.
The map is composed of n map line sections and each line has m
vertex.

Then
I read a jpeg image with the same resolution of the grid I have created and
I add it as a Texture to the main object root I
have.
The result is that I have the
map as a texture over the surface, but I have some
problems:
The
resolution is not to high, the map it's only seen when you put far away the
camera. If the camera is near to the surface you can see how image pixels are
related to the cells of the grid I have created. If I increase the resolution of
the image I loose the 1 to 1 relation between pixels and cells so cells become
enlarged and the image
becomes worst.
I see anywere smoother
textures applied to a surface but I don´t know which kind of mechanisms or
algorithms they use to do that, if anyone has any idea of how to do it or knows
where can I read about that it will be
appreciated.
Thanks for
advance.
Regards.
