please i would like help with an issue I have.
I have an imported image and I would like it to be scaled to full size as it is
currently at a scale that is not visible to the eye. below I have posted the
image
and the current code i have
// perspective (default, not required) camera
camera {
perspective
location <5, 5, -15>
look_at <0, 0, 0>
right x*2752/4896 // aspect
//direction<3129.6857,3102.3533,0>
focal_point < 563.2927,1366.9001,0.0>
aperture 3.6171875
// direction z // direction and zoom
// angle 67 // field (overides direction zoom)
}
plane {
z, 1
pigment {
image_map {png "image" once map_type 0 interpolate 2 } }
finish {ambient 1 diffuse 0}
scale 4
}

Here is how I would do it:
ini settings: +W2592 +H1944 // Set the output to the original size of
your image.
#declare image_width = 2592;
#declare image_height = 1944;
///////////////////////////////////////////////////////////////////////////////
// perspective (default, not required) camera
camera {
orthographic
// Less distortion with an orthographic camera
location <image_width/2, image_height/2, -10000
// Move the camera perpendicular to the center of the image
// and back in z
look_at <image_width/2, image_height/2, 0>
// Point at the center of the image
right x*image_width/image_height
// aspect the same as original image.
//direction<3129.6857,3102.3533,0>
focal_point <image_width/2, image_height/2, 0>
// I have never used focal_point before but I guess
// it needs to be the centre of the image
aperture 3.6171875
// direction z // direction and zoom
angle 14 // field (overides direction zoom)
}
box{<0,0,0>,<1,1,0.001>
pigment {image_map {"D:/Files/Photos/Historic boats/027.JPG" once
map_type 0 interpolate 2 } }
finish {ambient 1 diffuse 0}
scale <image_width, image_height, 1>
}
// Make a box from 0 to 1 in z and y, thin in z
// Add image (from 0 to 1)
// then scale to original aspect

well, most code, probably, I need a '#version' and things, too, to make POV-Ray
happy ;-). have included an alternative to m@b's suggestion, fwiw.
regards, jr.
-----<snip>-----
#version 3.8;
global_settings {assumed_gamma 1}
// dims, divided by 1000.
#declare w_ = 2.752;
#declare h_ = 4.896;
// map.
#declare p_ = pigment {
image_map {png "6dig.png" once map_type 0 interpolate 2}
};
// lights, camera, action.
light_source {<-1,1,-1>*1000 color srgb 1 parallel}
camera {
location <w_/2,h_/2,-15>
right x * (w_/h_)
up y
look_at <w_/2,h_/2,0>
}
box {
0, <w_,h_,.1>
texture {
pigment {p_}
scale <w_,h_,1>
}
}

good evening so i created a series of cylinders using the following code
sphere_sweep {
linear_spline
5,
<image_width,image_height, 5>, 0.5
<image_width, image_height, 6>, 0.5
<image_width, image_height, 7>, 0.5
<image_width, image_height, 8>,0.5
<image_width, image_height, 9>,0.5
tolerance 0.1
scale 0.9
//rotate<0.0169,0.5644,3.0455>
}
i want to overlay this image over the image imported to pov ray. i have 2 issues
tho the first been
1. it seems the cylinders are behind the image ? how do i bring them foward in a
way they can seen as an intergral part of the scene. secondly how do i put them
in the x and y plane

#2 - each point is a (3-vector) sphere centre, so just place them at convenient
locations.
#1 - so much depends. you could declare the sweep, then translate it so it
moves nearer the camera, eg
#declare theSweep = sphere_sweep { ... };
...
object {theSweep translate some_pos}

you are aware that the variables you use refer to the rendered image size, ie
your '+wnnn +hnnn' options?

All image map pigments are in the x-y plane, so you would use rotate x
to bring it into the x-z plane.
