I have a question/problem that I was hoping someone else could help me with…
I’m working on rendering some terrain/landscape. Currently I’m setting vertex colors based on height, (shades of green at low elevations going to brown and then white at the highest elevations.) I then apply a tiled texture and modulate it with the vertex colors.
While it looks okay, it doesn’t thrill me much. I was thinking about a couple of options, using multiple textures for the grid. Basically I would use different texures for mts (more rock looking) and more grassy looking textures for the plains but I’m not sure how to do this without having obvious seams when I switch to a different texture. And for that matter I’m not sure how to switch textures in the middle of a tri-strip. (is there a performance hit?)
The other thought I had is using the original height field to generate one texture (pre rendering), since I know the elevation I can then have this created texture reflect the topoloty, but the problem here is I’m not sure if using one texture for a large terrain (80x80) grid will look good up close. Or how big I should make it.
Maybe I just need some better textures to use.
Any help, suggestions, resources etc would be appreciated.
