[Bf-docboard] Errata 40 (and a little text)

[Cesarano, Baldassarre]

Note 1: append a dot to all titles of figures.
Note 2: "<para> + CarriageReturn + some text" produce an initial space !!!


-- section_mesh_modeling_hooks.xml --
	append a dot all titles of figures.
	Line 13: <para></para> ????
	Lines 6-8, 16,36,52: Remove first space
	Line 25: "empty object" --> "Empty object"
		"at the center" --> "and placed at the center" (?)
	Add after line 30: some like "Grabbing, rotating, resizing a hook will be equivalent to grab,rotate, resize underlying points." 

-- section_mesh_modeling_creases.xml --
	append a dot all titles of figures.
	Lines 6-8, 13-14, 20-21, 41,42, 67-68, 90-91: Remove first space


--- may be old ----
	Replace tag sequence
		<figure>...</figure>...</para>
	with 
		</para>...<figure>...</figure>
	in chapter_character_animation.xml



-- section_curves_taper.xml--
	Lines 6-8, 10-11, 32-33: Remove first space

	Line 12: "you have a" --> "you have the" (?)

	Line 18,58,72,98: append a dot all titles of figures.
	Line 25: Please change phrase: "selection...selection"

	-- I'm not shure, and the text is not clear --
	Line 14: "of the curve object" --> "of the previously beveled curve object"
		  (a simple curve not have a 'width'!)
	Line 33-34: ??? Only 1 curve is possible to write in!!
	Line 39: ...no sense:

-- With permission of Kenneth Styrberg (and the supervision of Eric) I suggest to add this (some image is required): ------------------------------
Start with a clear screen, in Top View (NUM-7), X horizontal and Y vertical,  move the cursor in -3,0 add a curve.
Name it "Taper"  (F9, then enter "Taper" in OB:).
You can show the name in the 3D Viewport pressing the "Name" button in the Draw panel of Object Context (F7).
Move the cursor in 3,0 (LMB about 3,0 then SHIFT-S and Cursor->Grid) add a curve Path (for example) and name it "Test". 
Move the cursor 3D elsewhere and add a Curve-Bezier-Circle and name it "Bevel".
Select the Test curve and enter in the BevOb: field "Bevel".
Now the "Test" curve became a tube(?cylinder?pipe?) whith a diameter of two Blender units and 4 units long (same diameter of the "Bevel" Circle).
With "Test" curve selected enter "Taper" in the TaperOb: field.
Now the diameter of the tube(?pipe?) vary and the shape resemble the "Taper" curve!
Select the "Taper" curve and enter in Edit Mode; play with handles.
The start point (left) of the "Taper" curve correspond to starting point (left) of the "Test" curve the ending point (right) of the "Taper" correspond to the right end point of the "Test" curve. All intermediate points are in proportional position (only X coordinate), indipendently from "Taper" or "Test" curve extention (along X axis).

Where the curve have Y coordinate = 1.0 the "Test" curve have the same diameter of the "Bevel" Curve.
Y < 1.0 the "Test" curve have a reduced diameter, > 1.0 is widened proportionally.

If the diameter of the "Bevel" is 2 units (radius=1) and the distance of the first and the last point of the "Taper" curve is the same of the horizontal len of "Test" Curve you can superimpose the two curves and the "Test" shape will follow the "Taper" shaper (but only for points of the "Taper" curve horizontally internals to his ends (?=extremity=first and last point?).
The "Taper" curve cannot have two values Y with same X (a shape like a C for example). In this case only the points with the maximum Y value are considered (you cannot construct a concave structure as a cave cup!).

It doesn't matter the distance of "Taper" and "Test" curve only proportions!

The vertical subdivision of the extruded object derived from "test" curve is the same of the vertical subdivision of the "Taper" curve and you can change with "Resol U:" value in the Curve Tools panel of Editing (in Edit Mode for "Taper").
The horizontal is the "Resol U:" for the "Test" curve in Edit Mode.

The "Taper" curve cannot be beveled in turn and then not even tapered otherwise the "Test" curve remain only beveled but not tapered.
In these chains only the first curve is tapered

You can transform the "Taper" curve in a 3D (F7 and 3D button) and try to move the handles in 3D but only the Y (in this example) value is considered.
