Topic: CGI-Brick-Landscape

Hi,

I try to create a CGI-Lanscape made entirely out of bricks. Sort of a voxel Landscape with Legostuds on top of each voxel. The problem is, it takes way too many polygons to create a decent landscape (open landscape with mountains in the background, where unfortunatly not much is obscured by foreground objects).

Some solutions, tricks i tried:

1) replace the Legostuds with low-poly studs, or even use bumb-maps. The use of bumb maps sometimes looks good, but not from all angles (from a birds point of view it is best). But still there are too many polygons even without studs.

2) Seperate the landscape into different layers that can be rendered seperatly. This is ok, as long as the landscape can be seperated that way. But even then, mountains in the background require to many polygons.

3) dont use voxels for the background. But this looks fake, because it should nevertheless look blocky, even if the individual voxels cannot be clearly seen anymore. I tried to play with "blocky-looking" textures, but it didnt satisfy me yet. But I think the solution should be in this direction eventually.

Has anyone experimented in that direction ? Any ideas how to cheat with the background (or even midground) ?
Any reasonable solution is probably generic, so it does not matter which 3D-software I use.

Thanks

I have tried using blender for any cgi purpose but I sadly cannot figure it out

Re: CGI-Brick-Landscape

I've done a couple of tests like that and have run into similar problems. Lightwave has a "LEGOizer" plugin that allows a user to generate a brick-built landscape from a mesh. Almost like a 3d mosaic filter. I haven't figured out any brilliant solutions yet, though.

I hope Smeagol sees this thread. I think he's done some landscape stuff before.

Re: CGI-Brick-Landscape

Well I use displacement maps to get the blocky look (run my terrain elevation map through photoshop's Mosaic filter to make it into blocks) and then I layer a bump map of the studs on top of that.  In some cases I layer the studs onto the actual displacement/elevation map as well, if they need to actually pop out for a closer shot.

Re: CGI-Brick-Landscape

Could we see an example of the bump map?

Re: CGI-Brick-Landscape

Yeah, it's like this:

Only much larger, with a few hundred studs each way.  Basically I calculated it so that the studs match up with the blocks of the terrain.

Re: CGI-Brick-Landscape

I do essentially the same thing. It can end up looking kind of strange if you don't make sure to match up the two maps. mini/XD

Oww, Smeag's pic goves me a headache.

01:19:15 <Smeagol> anyway
01:19:18 <Smeagol> I need to finish all these projects
Yes, that President.
