Skip,
With these new changes it is possible to make images using hdri and
radiosity. For a false-color (color that you add) implementation, use an
image_map mapped to a sky_sphere, and give the new colors ridiculously
high values.
An example might look something like this:
sky_sphere{
pigment{
pigment_pattern{
image_map{
tga"my_image.tga" interpolate 2 map_type 1
}
}
color_map{
[0 rgb 0]
[.5 rgb<1 2 10>]
[1 rgb 10]
}
}
}
You can make your own color_map for an image by placing the image_map
statement inside a 'pigment_pattern' block.
Standard pitfalls and benefits usually associated with hdri imaging
probably apply to doing this.... you might want to use a low-res image
for the hdri, and a hi-res image to be viewed in the background. Might
have to make one of the sky_spheres a real sphere with no_image added...
