Projecting a fill?????

Red — Sat, 08 Nov 2003 23:21:21 GMT

I have an object that the 2d view is projected. This maybe a stupid question. What I want to do is place a fill in 2d view, so can I fill read off the projection to make it an easy fix? I don't believe it’s possible but I wanted to here it from some gurus.

It is possible, using the PROJECT2 codes in the 2D script.

Have to check exactly what they are, and will come back before someone else beats me to it Don't have the docs handy ...

However, expect long regen times.

THE 2D SCRIPT SHOULD READ:

PROJECT2 3,270,2

EXCLAIM OUT THE REST OF THE CODE, IF ANY.

FROM PAGE 125 OF THE GDL REFERENCE

Normal Fill

if rf then
add2 0,-b/2
set fill JF
poly2_b 5, 2, JP, 91,
0-O,0,1,
a-T/2,0,1,
a-T/2,b,1,
0-O,b,1,
0-O,0,1
endif

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Projected FIll

I'm guessing a projected fill would be scripted like this??

if rf then
add2 0,-b/2
set fill JF
poly2_b 5, 2, JP, 91,
PROJECT2 3, 270, 2
endif

No,

Just put in

PROJECT2 3, 270,2

no poly2 is needed.

I don't think it's possible while we don't know the 2D shape.

PROJECT2 does the 2D projection of the shape(s) defined in the 3D script.

Just use:
PROJECT2{2} projection_code, angle, method
[, backgroundColor, fillOrigoX,
fillOrigoY, filldirection]
