To open this window, select the 'Operations->Heightfield->Clip heightfield' menu option.

This option can also be used to re-calculate the heightfield after, say, a modification to the design map. This will, however, invalidate the normals, attributes map, water map, light map and texture. This option will only be greyed-out if you have closed the design map in a design-level project. text/html 2017-08-31T07:00:18+00:00 http://www.bundysoft.com/docs/doku.php?id=l3dt:userguide:ops:hf:h_scale&rev=1504162818&do=diff To change the horizontal scale of the heightfield you should select the 'Operations->Heightfield->Change horizontal scale' option in the menu, which will open up the enter heightfield horizontal scale window shown below. text/html 2015-06-25T11:33:09+00:00 http://www.bundysoft.com/docs/doku.php?id=l3dt:userguide:ops:hf:preview&rev=1435231989&do=diff L3DT allows you to generate a preview of the heightfield. The preview can be at lower, equal or higher resolution than the full heightmap, and can be of either the whole heightfield or a sub-region thereof. To generate a preview of a sub-region, first use the select area tool on the design map to select the area to be previewed, as shown below. If you are generating a preview of the whole heightfield, please skip this step. text/html 2011-01-13T04:00:26+00:00 http://www.bundysoft.com/docs/doku.php?id=l3dt:userguide:ops:hf:resize&rev=1294891226&do=diff To change the width and/or height of the heightfield, select the 'Operations->Heightfield->Resize heightfield...' option in the menu. This will open the 'resize map' window, shown below: L3DT might get upset if you resize the heightfield in a project with a design map, as each design map pixel will no longer correspond to a square tile of heightfield pixels (e.g. 64×64, which is default). Consequentially, several calculations will complain. Thus, you should not resize a heightfield in a proje… text/html 2017-08-31T05:47:47+00:00 http://www.bundysoft.com/docs/doku.php?id=l3dt:userguide:ops:hf:smooth&rev=1504158467&do=diff If you find your terrain to be too rough or noisy, you may use the smoothing filters remove high-frequency (i.e. small-scale) noise without changing the overall shape of the terrain, such as demonstrated below: [:l3dt:userguide:ops:hf:smooth:smooth_before.jpg] [:l3dt:userguide:ops:hf:smooth:smooth_after.jpg] Before smoothing After smoothing text/html 2017-08-31T04:36:23+00:00 http://www.bundysoft.com/docs/doku.php?id=l3dt:userguide:ops:hf:v_scale&rev=1504154183&do=diff You may find that after generating your heightfield that it's too steep or flat, should be moved up or down, or perhaps the sea coverage should be changed. The change heightfield vertical range window (below) allows you to do all this, and is accessed from the 'Operations->Heightfield->Change vertical range' option in the menu.
