Hello,
I'm trying to convert to POVray 3.5 an Ant model made Micha Riser for
MegaPOV 0.5 (found http://objects.povworld.org/).
When I trace the example file, I got the following error
Parsing.....................File: ant.inc Line: 122
sphere_sweep{
catmull_rom_spline_sphere_sweep
<----ERROR
Parse Error: Invalid type of interpolation.
and the corresponding source file is :
union{
sphere_sweep{
catmull_rom_spline_sphere_sweep
#declare rscale=0.4;
6
0,0.275*rscale
0,0.25*rscale
<-.2,0,1>,.22*rscale
<-.3,0.15,2.8>,.3*rscale
<0,0.3,4.8>,.35*rscale
<0,0.3,4.8>,.35*rscale
rotate y*90
rotate z*90
...
There is another 'sphere_sweep' later :
sphere_sweep{
linear_sphere_sweep
21
0,0.25
#while(ss_anz<10)
...
and pov complain about linear_sphere_sweep.
So my question is obvious : how can I convert these bit of code to
something understandable by POVRay ?
Thanks & regards,
Laurent

Use "cubic_spline" and "linear_spline" instead of
"catmull_rom_spline_sphere_sweep" and "linear_spline_sphere_sweep".

Unfortunately, I got many errors :
.File: ant.inc Line: 171
Warning: Should have at least 2 objects in csg.
File: ant_example_scene.pov Line: 68
Warning: Unnecessary bounding object removed.
I will install MegaPov, anyway, thanks for your reply.

Probably an union with only one component, you may change "union" for "object"

The file contains some manual bounding "object" that are not needed. Remove any
"bounded_by..." you
can find.

I believe you'll get those same warnings with MegaPOV. Warning messages
don't stop the image rendering, they just notify you of things that the
program suspects might be badly written.

Yes, you're right : so I remove offending lines and now the test scene
compute succesfully w/o warning using POV 3.5 on my SUN workstation.
The result is very pretty and ants are very realistics.
A big "thank you" for Alain & you for your help, and obviously for Micha
for he original code.
Bye
Laurent
PS: I'll make some cleaning and I will upload this new version to
http://objects.povworld.org/
