Here is an interesting test shot showing a terrain rendered by displacement mapping.

Using a grid of flat meshes and a large (4096*4096) heightmap, I have done a vertex texture read to displace the vertices in the vertex shader.

This method is interesting in that it can use mesh LOD for the individual patches, allowing for extreme detail up close.

unfortunately there is no trivial way to make sure that the edges of the patch meshes line up seamlessly.. currently I am working a solution for that however. Also there is the issue with wierd frustum culling. Perhaps this can be solved by increasing the bounding box size.

This is part of my research into new technology for my Sphere Engine...

Test shot? What is that?

EDIT: Can anyone on this planet see a picture here? I guess only Matt himself....

Can't see the screenie Matt

Yes there is supposed to be a screenshot.. I guess you cant access my server..

Well, firefox is loading, but the picture doesn't show for me either. Perhaps you can use something like imageshack or if you'd like I could host it,

Cheers

it worked for me :/ i like it

site source text says, http://matt.brightwatch.com/disp.jpg, but i can't see it either.

too bad. cant you upload it to imageshack?

how do you do it? i tried using vs3_0 but i got errors if i try to use the result of the texture read

I can see the picture on my mobile phone, a greyscale terrain file with orange skybox[edit: lol, okey yellow? ]. The greyscale terrain has the displacement mapping. Looks pretty cool, reminds me a little bit of voxel engines because it has this rough look. I can't download the picture and re-upload though,

Cheers
