Hey all; got a small problem with some spline code. Here it is.
//begin file
#include "colors.inc"
camera{location <5,30,-60>
look_at<0,0,0>
}
light_source{<1000,1000,-1000> White}
background{Gray50}
prism {
conic_sweep
linear_spline
.5, // sweep the following shape from here ...
1, // ... up through here
9, // the number of points making up the shape ...
<0,1.5>,<1.5,0>,<31,0>,<32.5,1.5>,<32.5,15>,<31,16.5>,<1.5,16.5>,<0,15>,<0,1
.5>
translate<-16.25,0,-8.25>
rotate <180, 0, 0>
translate <0, 1, 0>
scale <1,6,1>
pigment{Green}}
//end file
Now I tried this without the first translate statement, and it was not
symmetrical, it seemed to extrude the spline strangely; so I thought my
points needed to center around the origin, which is what the first translate
should do; but I noticed no change. Also; is there a way that I can specify
the angle the spline extrudes at? And this question is mainly for Ken:
1)how do you export something from AutoCad to a format POV can use, and when
you do it is mesh based correct? 2)can you still do CSG and transparent
textures and all that with such objects?
Thanks guys.
