Is this the wrong place to post this question? I figured since I was
attaching images to illustrate my problem it'd be best to start here.
Based on my previous understanding of image_maps, and the documentations
description, my image isn't coming out as expected...
I have a PNG of my company's logo. I made the background transparent
leaving the white and gray parts. I created a box object, applied an
image_map of the logo. I expected to see the white and gray portions of the
logo extruded along the Z axis from the front of the box to the back.
Instead, the image is appearing flat against the front of the box (-z, for
the purposes of this scene., flat against the back of the box (+z), with
emptyness in the middle... Is it because I'm using alpha channel
transparency? Am I doing something dumb? Or do I just STILL (after 10
years since my rsocp) still not have a grasp on the basics??? I've tried
things like scaling the texture along the z axis, making the box hollow,
then not hollow, then using interior_texutre... none of these I expected to
work, but...
I'm attaching 2 renders, jpg, cropped to make smaller files, and the full
.png image I'm using as my image map.
The code:
// An area light (creates soft shadows)
// WARNING: This special light can significantly slow down rendering times!
light_source {
0*x // light's position (translated below)
color rgb 1.0 // light's color
area_light
<20, 0, 0> <0, 0, 20> // lights spread out across this distance (x * z)
4, 4 // total number of lights in grid (4x*4z = 16 lights)
adaptive 0 // 0,1,2,3...
jitter // adds random softening of light
//circular // make the shape of the light circular
//orient // orient light
translate <40, 40, -40> // <x y z> position of light
}
plane {
y,
0.0
hollow on
material {
texture {
pigment {
color rgb <1.00, 0.95, 0.90>
}
}
}
finish {
specular 1
reflection 0.3
crand 0.02
diffuse 0.5
}
}
box {
< 0.00, 0.00001, 0.05> // one corner position <X1 Y1 Z1>
< 5.76, 4.08, -0.05> // other corner position <X2 Y2 Z2>
material {
texture {
pigment {
image_map {
png "dg.png"
once
}
scale <5.76, 4.08, 1>
}
}
}
}
Any thoughts???
Thanks!
