Heightmap problem

kulesz · 05-29-2011 01:00 PM

Hi,

I'm using the new "Edit::heightMap" feature to generate some heightmap meshes from perlin noise (I use libnoise library to generate the noise arrays).
Everything is fine until I try to render few heightmaps side by side - I'm trying to make huge map from few smaller ones. The border vertexes' values of two neighbor heightmaps are exactly the same, but the shadows look somewhat broken. Some screens are attached.
Is there some way to fix it?

Try using smooth function with speed and size at minimum and soft at max. Not guaranteed to work but that was what I did with a mosaic.

You have to run down the seam.

The problem is, that theoretically they are seamless. Vertexes on left side of one heightmap are exactly the same are the ones on the right side of second heightmap - there are no gaps etc. Just this shadow/seam effect on the texture is causing a problem.

in the build method you need to pass heightmap neighbors pointers

Hmm, ok, and how to enable colisions with the generated terrain?

create phys/actor from mesh

Well, I've tried to combine my app with the dynamic object creation tutorial.
After doing:

Code:

Mesh *m_temp;

PhysBody   phys ;

Actor      actor; 

m_temp = new Mesh;

m_temp = create_mesh_from_heightmap();

phys .parts.New().createMesh(*m_temp); // create physical body from 'mesh'

actor.create(phys);

After hitting space, a new barrel appears, but it comes through my terrain :/
