Greetings,
I do believe I've stumbled across a bit of a problem with
cutaway_textures in v3.7beta36. I've had two other users confirm the
behavior before posting here for wider confirmation. In a nutshell v3.6
cutaway_textures works as advertised, and with the current beta the
difference part traces black. Here's the simple scene:
---
#include "colors.inc"
#include "woods.inc"
camera {
perspective
location <-1.5, 1.5, 2.5>
look_at <0, 0, 0>
right x*image_width/image_height
}
light_source {
<-10, 10, 10>
color rgb 1.0
}
background {rgb <0.5,0.175,0>}
plane {y,0 pigment {rgb <0.5,0.175,0>}}
difference {
box {<0,0,0>, <0.5,0.25,1>
texture {
T_Wood1
scale <0.5,0.25,1>
translate <0.25,0.125,0>
finish {ambient 0 diffuse 1 }
normal {agate 0.1 scale 0.1}
}
}
cylinder {<0,0.25,-0.2> <0,0.25,1.2>, 0.05}
cutaway_textures
}
---
also found something of lesser importance ... woodmaps.inc depends on
colors.inc, more specifically the definition of the color "Clear"
perhaps a #ifndef colors.inc belongs in woodmaps.inc or probably more
correctly changing the call of "Clear" to rgbf 1
