Fantastic Banners (aka simple flag sim.)


Sticking with the theme of physics sims, here's a very simple flag.

This version is with a higher definition for the flag. So it looks a bit smother.

Hi Dom

I tried this not long ago and it works really well!! So I'd assume this is kind of a "voxel" style setup, with sprite voxels? I've had DIV crash before when trying to set up sprite bars to simulate railings etc, so Im surprised this works :D Is this set up with some kind of 3D grid arrangement, then?

And how high res do you think you could run a 3D "object" like this before DIV starts to have serious problems? Have been considering using something like this to make basic 3D objects like alarms, security cameras, tables, etc.

Hi BC,
Sorry for not replying until now, I've been off the computer for a while.

Unfortunately this thing is pretty limited for the purpose of making 3D objects. Each voxel is a process (this allows the mode 7 engine to handle the position in 3d space) . The problem is that using a process for a voxel is highly wasteful. More than a handful will overwhelm the computer (mine anyway).
The system could be used to do a cool version of something like "Robotron" though.

hmm, well surely if making any 3d objects where two voxels have to be on top of eachotha then itd be okay to just render that as a one "voxel"/process vertical bar? that could reduce the load on the system. I managed to make some things like caution tape, criss cross wire fences etc using sprite bars so maybe it'd be possible to do something similar with voxels.

Does your system involve a struct/three arrays for X, Y and Z coordinates, by the way? like say, having a central process to call voxel(voxelgraphic, voxel_x[vnum], voxel_y[vnum], voxel_z[vnum]); or similar?
