=============================================================================
                                  HINTS
=============================================================================

A little explanation about LEN and TEXLEN. With those you can specify the
size of the texture on the polygon. For example, let's say that you have
a rectangular polygon which is 4 units wide and 6 units high. A texture with
LEN set to 2 will be tiled 2 times horizontally and 3 times vertically.
If this texture is 128x128 (for example) then the final texture on the polygon
will be 256x384.


Using a TEXTURE statement inside a POLYGON or with a PLANE statement you can
get even more control on how the texture should be scaled accross the polygon.
I will explain it with an example. Say that you have a polygon like this:
	VERTEX (0,2,3) VERTEX (2,2,3) VERTEX (2,0,3) VERTEX (0,0,3)
	POLYGON 'xxx' (VERTICES (0,1,2,3))
Let's say that you want to align the texture so that it's origin is at (2,2,3).
You can do this as follows:
	POLYGON 'xxx' (VERTICES (0,1,2,3) TEXTURE (ORIG (2,2,3) FIRST (0,2,3)
			SECOND (2,0,3) FIRST_LEN (1) SECOND_LEN (1)))
With ORIG, FIRST, and SECOND you specify how the u/v coordinate system is
located. The origin of u/v is at ORIG, the u-axis is at FIRST-ORIG, and
the v-axis is at SECOND-ORIG. FIRST_LEN and SECOND_LEN are simlar to LEN
and TEXLEN except that you can control the u and v scaling seperately here.
Note that ORIG, FIRST, and SECOND need not coincide with vertices of the
polygon. They should just be on the same plane as the polygon. That way
you can also create slanted textures.


TEXLEN in a THING or SECTOR is the default LEN for all polygons following
the TEXLEN declaration.
TEXNR in a THING or SECTOR is the default TEXNR for all following polygons.


PLANE's are good and recommended. A PLANE is just a way to give a name to
a texture orientation. All polygons sharing the same PLANE will have
textures that fit perfectly at the borders. CS will also be able to do
some optimizations on polygons that share the same plane (like backface
culling a whole set of polygons in one go). Note that even if a PLANE is
only used by one polygon it does not hurt. If you did not specify the PLANE,
Crystal Space would have created one anyway.


Currently Crystal Space assumes that there is a sector called 'room'. It
will use that as a starting place. It will also always start at location
(0,0,0).


Note that SECTOR's must be convex (unless you add a BSP tree).


Note that THING's need not be convex.


Vertices in a THING are specified in local object space. You can translate
this object space to world space with the MOVE statement.


When a THING or SPRITE is defined in the WORLD statement and not in a
SECTOR or ROOM then you define a template. This template can then be
used inside a SECTOR or ROOM by giving another THING or SPRITE statement
and using the TEMPLATE statement there. It is also possible to define
the THING or SPRITE inside the SECTOR or ROOM but using templates is
preferable.


With WARP you give a matrix which will mirror space. For example, when you
want to make a mirroring floor the warping matrix should invert Y and leave
the others intact. So the WARP matrix is:
    / 1  0 0 \
    | 0 -1 0 |
    \ 0  0 1 /
The vector should be a vector on the plane of the mirror. It is used to
determine where exactly mirroring should start. If the floor is at height
-1 (for example) so <0,-1,0> is a good spot.


Note that PORTAL's are one-direction only. If you need a PORTAL that works
in two directions (so that you can go back) then you'll also have to specify
a PORTAL in the other sector pointing back.


Note that even though a PORTAL does not require a texture (unless it has
alpha transparency) you still need to specify one. The current CS code
assumes that every polygon has a texture.


The ROOM and SIXFACE interface is good for human editors but it is not suited
for computer generated output. Ignore ROOM and SIXFACE if you want to write
an editor or convertor and concentrate on SECTOR and THING instead.


MATRIX (.5) is a shorthand for:
    / .5 0 0 \
    | 0 .5 0 |
    \ 0 0 .5 /
