3.9 The Commands Panel

The Commands panel lets you type in a GCL command. When you hit <Enter>, Geomview interprets the command and prints any resulting output or error messages on standard output. You can edit the text and hit <Enter> as many times as you like, in general, whenever you hit <Enter> with the cursor in the Commands panel, Geomview tries to interpret whatever text you have typed in the text field as a command.

[Move this.] Normalization is a kind of scaling; Geomview can scale an objeto so that it fits within a certain region. The main point of normalization is to allow you to easily view all of an objeto without having to worry about how big it is. We are gradually replacing Geomview's normalization feature with more robust câmera positioning features. In general, the best way to make sure you are seeing all of an objeto is to use the Look At botão on the Tools panel. Normalization may be completely replaced by this and other features in a future version of Geomview.

Normalization is a property that applies to each geom separately. The NORMALIZE GEOMETRY browser affects the normalization property of target geom. If the target geom is "World", it affects all geoms.

None

Do no normalization.

Individual

Normalize this geom to fit within a unit sphere.

Sequence

This resembles "Individual", except when an objeto is changing. Then, "Individual" tightly fits the bounding box around the objeto whenever it changes and normalizes accordingly, while "Sequence" normalizes the union of all variants of the objeto and normalizes accordingly.

Keep

This leaves the current normalization transform unchanged when the objeto changes. It may be useful to apply "Individual" or "Sequence" normalization to the first version of a changing objeto to bring it in view, then switch to "Keep".
