Hi Mike
You can try this:
// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7
#version 3.7;
#include "colors.inc"
global_settings { assumed_gamma 1.0 }
// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7
#declare Box =
box {
-<1, 1, 1>, +<1, 1, 1>
translate <-1, -1, +1>
pigment { color (White + Blue)/2 }
}
#declare Text =
text {
ttf "timrom.ttf" "POV-Ray..." 1, 0
pigment { color (White + Red)/2 }
}
// For aligning to an isometric perspective grid
// often used in computer generated graphics
#declare Skew =
transform {
matrix <
+1.0, -0.5, 0.0,
+2.0, +1.0, 0.0,
0.0, 0.0, +1.0,
0.0, 0.0, 0.0

}
object {
Box
transform { Skew }
}
object {
Text
transform { Skew }
}
// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7
light_source {
-100*z
color White
}
camera {
orthographic
location -z
right image_width/image_height*x
up y
direction z
scale 10*<1, 1, 1>
}
// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7
