Creating Land for a Scene

Restart Seamless3d and then click rectangle_build_button to add a Rectangle.

Click open-control-panel-button to open the control panel for the Rectangle and tick the yCentred field.

With the control key held down, click the up x rotation button:

to rotate the rectangle on the x axis 90 degrees so that the rectangle lies flat on the grid.

Set the xDistance and yDistance fields to 100 to set the dimensions of the land to 100 by 100 meters:

Using the mouse wheel Zoom out until you see all of your land.

Click to convert the rectangle to a single patch.

Increase the number of control_staves and control_bands to 6 and then click done:

Click open-control-panel-button to open the control panel for the patch and click the mirror checkbox to clear it:

If we now click wireframe button to toggle into wireframe mode we will see the triangles are not dense enough to create curves for our land:

To generate denser triangles, click one of the patch's control points and then press Control F4:

We can now drag the control points to create hills in our land.

To ensure that we only drag the land points straight up or down from any view angle: click transform-lever-control-panel-button to open the Transform Lever's control panel and ' then set the leverSelection field to 1:

We won't need to change the leverSelection in future versions so don't worry about why we are doing this if you are a beginner.

Click dim-tug-filter-button and then drag the green arrow point above our selected control point. We can drag more points this way without clicking dim-tug-filter-button again if we hold down the tab key while clicking and dragging the control points.

We can click a control point to select it without accidentally moving the control point if we hold down the control key while clicking the point.

If we are having touble seeing all of the control points due to the triangles hiding the control cage, we can click zbuf cage button to toggle to zbuf cage button

To paint the land, click paint-mode-button to go into paint mode.

Click brush-button to select the paint brush. To paint with the brush drag the mouse over the land. The radius of the brush can be changed by holding down the control key while scrolling the mouse wheel.

Click palette-button to open the palette window. Any colour can be set for the brush by selecting the colour in the palette window:

A simple way to set the colour of the sky is to click scene tree button to open the scene tree window and then clicking (the scene node) to open the scene node's control panel. The scene node's backgroundColour field sets the colour of the sky:
