So... many many many years ago I used to use POVRay and the thing I liked about it is the scenes were scripted in their own files.
You could not only describe the scene but also use variables to start doing animations with batch files. I wrote an DOS based animation tool in Turbo Pascal that did all sorts of weird and wonderful things. Things like moving objects (the camera and lights are counted as an object) along bezier curves, catmull-rom spline curves etc.
So anyway to get to the point it would really make this far more accessible if a text file could be used to describe a scene. So things like objects, textures, camera, lights etc could be defined in a far simpler file that is called by the Python code.
I'd be happy to help with how it should look and do testing. Perhaps a simplified version of the POVRay scene files could be a guide.
Another thing that can be done of course is (as you will see in the example below) separating out textures into their own files for modification. :)
For example a basic scene would look like this:
//EXAMPLE OF SPHERE
//Files with predefined colors and textures
#include "colors.inc"
#include "glass.inc"
#include "golds.inc"
#include "metals.inc"
#include "stones.inc"
#include "woods.inc"
//Place the camera
camera {
sky <0,0,1> //Don't change this
direction <-1,0,0> //Don't change this
right <-4/3,0,0> //Don't change this
location <30,10,1.5> //Camera location
look_at <0,0,0> //Where camera is pointing
angle 15 //Angle of the view--increase to see more, decrease to see less
}
//Ambient light to "brighten up" darker pictures
global_settings { ambient_light White }
//Place a light--you can have more than one!
light_source {
<10,-10,20> //Change this if you want to put the light at a different point
color White*2 //Multiplying by 2 doubles the brightness
}
//Set a background color
background { color White }
//Create a "floor"
plane {
<0,0,1>, 0 //This represents the plane 0x+0y+z=0
texture { T_Silver_3A } //The texture comes from the file "metals.inc"
}
//Sphere with specified center point and radius
//The texture comes from the file "stones.inc"
sphere { <0,0,1.5>, 1 texture {T_Stone1} }
