Can edit terrain node, but normals won't update!

Hi Everyone,

I've been playing with changing a terrain node dynamically, can now adjust the positions of the individual vertices with the following code (which is just a test) :

Code: Select all

scene::IMesh* pMesh = terrain->getMesh();
     
    s32 b;
    for (b=0; b<pMesh->getMeshBufferCount(); ++b){
        scene::IMeshBuffer* pMeshBuffer = pMesh->getMeshBuffer(b);
        // skip mesh buffers that are not the right type
        if (pMeshBuffer->getVertexType() != video::EVT_2TCOORDS) continue;
     
        video::S3DVertex2TCoords* pVertices = (video::S3DVertex2TCoords*)pMeshBuffer->getVertices();
 
        u32 vertCount = 262144; // (512*512)
 
        // adjust vert position
        for(int i=0; i<65536; i++)
        {
            S3DVertex currentVert = pVertices[i];
            currentVert.Pos.Y = 500;
            currentVert.Normal = vector3df(0,1,0);
            pVertices[i] = currentVert;
 
            int a=1;
        }
 
    }
    
    // force terrain render buffer to reload
    terrain->setPosition(terrain->getPosition());

Problem is, can't find a way to make the normals update as well (setDirty doesn't make any difference) :



Need help pretty badly, have spent a couple of weeks on this and have run out of time to get it going

Sorry, I'm a goose, got the image url wrong... (fixed now)

Use SceneManager->getMeshManipulator()->recalculateNormals
