  Balls on a grid (Message 1 to 8 of 8)

Hello Everybody!

I trying to arrange labelled balls on a grid (see subsequent code). The
problem is that the balls look like pool balls. To become more reliable I
would like use uni-colored balls labelled with black text.


error.

In the web I just found examples with text in a glass ball or text growing
out from a ball. Unfortunately all my attempts to modify failed.



Thanks in advance!

Ralf

Just a quicky but substituting this  macro:
//start code
#macro MakeBall(Text, SpotSize, SpotClearance, ColorTex, WhiteTex)
     #local Mn = min_extent(Text);
     #local Mx = max_extent(Text);



#declare TextTexture=texture{
         pigment{object{Text colour Clear colour Black}
             translate -Mn - 0.5*(Mx-Mn)
             scale  x + y + z*1/(Mx.z - Mn.z)
             scale (x+y)*(SpotSize-SpotClearance)/vlength(<Mx.x, Mx.y, 0> -  
<Mn.x, Mn.y, 0>) + z
             translate -z*1
        }}

sphere  {< 0, 0, 0>, 1
texture{pigment {cylindrical color_map{[0 Black][0.2 Black][0.2 White][1  
White]}rotate x*90}}
texture{TextTexture}
}


#end
//end code

Just one side of text though, I'll let you play with the other side  and  
Substitute the colours :)

Okay, Phil posted a reply since I started messing with this, but here 
goes anyway....

I've typically added text to simple shapes a different way - I make a 
union of the base object and an intersection of the "text" with a 
similar shape that is very slightly larger.  That way the text is above 
the sphere/cylinder, but imperceptibly so.  Sort of what would happen if 
the text was a layer of paint on the object surface.

In your case, the face color can be applied the same way, too.  I 
modified your macro, adding a "text" texture at the end (and the scaling 
and translation is unnecessarily different, since I was tweaking it to 
see what you were doing).   In any event, here's an example of what I mean:

-------- SNIP --------
#macro MakeTextBall(Text, SpotSize, SpotClearance, SphereTex, FaceTex, 
TextPig)
     #local TextObj = text {ttf "crystal.ttf", Text, 1, 0 };
     #local Mn = min_extent(TextObj);
     #local Mx = max_extent(TextObj);
     union {
	// First, the sphere:
	sphere  {< 0, 0, 0>, 1 texture {SphereTex}}
	// Next, the color behind the text:
	intersection {
	    cylinder {-z*2, z*2, SpotSize/2}
	    sphere { <0,0,0>, 1.0001 }
	    texture{FaceTex}
	}
	// Last, the text:
	intersection {
	    union {
		#local ii=0; #while (ii<2)
		object {TextObj
		    translate -Mn - 0.5*(Mx-Mn)
		    scale 
<-1,1,0>*(SpotSize-SpotClearance)/vlength(<Mx.x,Mx.y,0>-<Mn.x,Mn.y,0>)+z/(Mx.z-Mn.z)
		    translate -z*1
		    #if (ii) rotate 180*x #end
		}
		#local ii=ii+1; #end
	    }
	    sphere { <0,0,0>, 1.0002 }
	    texture{TextPig}
	}
     }
#end
-------- SNIP --------

In this case the sphere is 1.0000 in radius, the "face" color is 1.0001 
and the text is 1.0002 -- giving the layered effect I was trying to 
describe.

Note that this method doesn't "wrap" the text, so if the text covers 
much of an arc on the object, it may be distorted too much.

This way will be slower and consume more memory than simply using the 
object pattern. It is also more likely to cause artifacts from precision 
problems, and is very difficult with more complex shapes, though it is 
easy with spheres.

Out of curiosity is there an easily explainable :) reason why you can't 
layer multiple object patterns? The obvious answer to this otherwise would 
have been to create the differenced cylinders texture and layer the text 
texture on top.

You can nest them, which lets you accomplish the same things. The object 
pattern is about as simple as a pattern can get, supporting multiple 
objects would be a lot more complex. I have been thinking about such a 
patch, though...or rather, two similar patterns, one which "layers" each 
object over the previous ones, and another which averages overlapping 
objects together.

Of course! silly me that would allow you to remove the MakeBall macro and  
just have:

//code
#macro MakeTextBall(Text, SpotSize, SpotClearance, OuterColor, SpotColor,  
TextColor)

   #local TextObj =
     text {ttf "crystal.ttf", Text, 1, 0 }

     #local Mn = min_extent(TextObj);
     #local Mx = max_extent(TextObj);



#declare Texttexture=
         pigment{object{TextObj colour Clear colour TextColor}
             translate -Mn - 0.5*(Mx-Mn)
             scale  x + y + z*1/(Mx.z - Mn.z)
             scale (x+y)*(SpotSize-SpotClearance)/vlength(<Mx.x, Mx.y, 0> -  
<Mn.x, Mn.y, 0>) + z
             translate -z*1
        }

#declare Spottexture=
         pigment{object{difference {
             cylinder {-z*2, z*2, 5}
             cylinder {-z*2, z*2, SpotSize/2}
         }
        colour SpotColor colour OuterColor}}

#declare Spheretexture=texture{pigment{Spottexture}}  
texture{pigment{Texttexture}}

sphere  {< 0, 0, 0>, 1
texture{Spheretexture}
}


#end
//end code

Remove all those ...Tex #declare's and put the colours directly in the  
call, adding in the colour of the text directly as part of the macro:
//code
object {MakeTextBall("NM_8", 1.5, 0, Green, White, Black)
     rotate x*100
     rotate z*350
     translate z*0
     translate y*0
     translate x*0
}
//end code

Have fun :)

Dear Phil

Thank you for your advice. Your first solution already works pretty well.

An other very good solution was mailed directly by Friedrich. Because this
might be of interest for any Newbies working on similar problems, I list
the code below.

Thanks to all of you for your help :-)
