XYZ data into AC3D

[Andy]

Got the file. Due to the precision used in Create Mesh function, the best thing for this model is to size the whole model to 1x1x1 (SizeTo) and then do the Vertex->Create-2D-Mesh->Front. (you can try this in sections, otherwise, looking at 40,000 vertices will take a long time to complete)

OK, thanks for having a look. The file is just too big, even doing small sections doesn't work, but when I do a new model, make a mesh remove surface move vertises and then make a new surface, it does. Something wrong with the file format I think.

I did it with the file you sent (see pic above).

I simply clicked on SizeTo (1x1x1) first.

The projection you select is important. In this case, I used Vertex->Create-2d-mesh->front.

Look the field plugin:

The first two numbers in the file are the x, y size of the grid.
this is followed by (x*y) heights in row order.

If you can get your data like this (all you really need ar the point heights and the size of the grid), You'll get a better mesh.

[Mossie]

What field plugin are you refering to ?

Don't understand.

[Andy]

In AC3D, select menu Help->About-Plugins and select the Field Import Plugin from the list - this will tell you more.

Ok, found that pf file format, I assume is:

grid x grid y
pos x pos y height z
pos x pos y height z

Or should it be
grid x grid y
height z
height z

If the first then I've a new error
"myalloc 8 failed
unable to alloc 8 bytes"

I think this is a file error, thoughts please.

[Andy]

It should be:

grid_x grid_y
height_z
height_z...

e.g. I made this up:

3 3
1
2
2
3
1
2
3
4
2

This is a 3x3 grid of points.

Mossie, what cool weirdness are you up to with that terrain chunk...?

Do tell.

[Mossie]

The plan is to be able to build towns and villages with the correct locations and heights for all buildings. Also for bridges and such. Doing this outside the terrain, and testing in game is too long winded. Once the models are built and placed the terrain is discarded.
