Node Description and Purpose
The Landmark node is a special type of object node. It only shows up in the 3D Preview - it doesn't show up in final renders. The Landmark node can be useful for marking points of interest in a scene. It can also help with judging scale and distance.
The quickest way to place a Landmark is to context click in the 3D Preview where you want the Landmark to go and then choose "Copy Coordinates". This copies the location of the terrain under the mouse. You can then paste the location into the Landmark's position param using the param's Copy/Paste button.
If you want to quickly move a camera to a Landmark location you can choose it from the "Snap to object or shader" menu in the 3D Preview. You can see this menu by context clicking in the 3D Preview or clicking on the Reset Camera button below the 3D Preview.
Node Type: Object
- Type: This popup lets you choose the type or shape of the Landmark. You can choose from a flag, arrow, cube, sphere, donut, diamond, pyramid or teapot.
- Colour: You can set the colour of the Landmark object with this param.
- Display mode: This popup lets to choose whether the object is displayed as a solid or wireframe. Please note that the display mode of the landmark objects is not effected by the 3D Preview object display mode.
- Position: Set the position of the Landmark.
- Rotation: Set the rotation of the Landmark.
- Scale: Set the scale of the Landmark in metres.
A single object or device in the node network which generates or modifies data and may accept input data or create output data or both, depending on its function. Nodes usually have their own settings which control the data they create or how they modify data passing through them. Nodes are connected together in a network to perform work in a network-based user interface. In Terragen 2 nodes are connected together to describe a scene.
Context clicking shows a contextual menu. On Windows this would normally be done with a right click. On OS X this could be a control-click or a right click.
A shader is a program or set of instructions used in 3D computer graphics to determine the final surface properties of an object or image. This can include arbitrarily complex descriptions of light absorption and diffusion, texture mapping, reflection and refraction, shadowing, surface displacement and post-processing effects. In Terragen 2 shaders are used to construct and modify almost every element of a scene.
