A strange bug with rounding coordinates Created 19 years ago2005-01-18 18:24:25 UTC by ant222

With Revolver Beta 1 I made a torus. The "Round Float Coordinates to Integers" option was unchecked (it seems not to work). As a result, the torus was good but had many vertexes with non-integer coordinates.

After saving it in the .map format (from Hammer) the torus got unstuck. The sections forming it separated from each other. Now all the vertexes were in grid nodes (i. e. had integer coordinates).

The question is why the rounding of coordinates is made in such a weird way. Why mathcing (i. e. having equal coordinates) vertexes of different (adjacent in the initial torus) sections are snapped to differetnt grid nodes, so that the resulting figure collapses?

I think the coordinates of all the vertexes might be rounded in the same way so that the resulting body wouldn't fall to pieces but just be slightly deformed (due to rounding).

The map format isn't really made for complex solids like that - you could try making it manually with Vertex manipulation or making Revolver do less segments.

The rounding thing is strange, but the numbers actually define "planes", and not individual vertexes. This is why you get strange numbers for even the simple geometry if you look at the .map

The errors get worse with the programs interpreting Floating point Integers (evil buggers).

On an unrelated note - this is the smartest post i've ever seen on TWHL.

Oh, and by smart i ment:

"Wow! OMG! a question with some background knowledge!"

Yes, welcome. Your name is similar to my other net name (Ant292).

Floating point Integers

Eh?

oops... "integers" should not be in there at all

my mistake.
