Node Description and Purpose:
The Geog heightfieldA heightmap or heightfield is an array of height values, usually in a grid which describe the height at specific points in a defined area. Heightfields are used to represent real-world and virtual terrain in a specific, easily converted format. Most heightfields can be represented as simple image data in grayscale, with black being minimum height and white being maximum height. load nodeA 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. can load and georeference digital elevation map (DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars.) files. It supports many formats and projections. Geog heightfieldA heightmap or heightfield is an array of height values, usually in a grid which describe the height at specific points in a defined area. Heightfields are used to represent real-world and virtual terrain in a specific, easily converted format. Most heightfields can be represented as simple image data in grayscale, with black being minimum height and white being maximum height. load nodes can be created using the "Heightfield (load DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars.)" item in the Add Terrain button menu at the top of the Terrain nodeA 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. list.

You can see a list of the supported DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars. formats supported by the nodeA 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. here. TG3 supports all of the formats which have "Yes" in the "Compiled by default" column of the table on that page. Most commonly used DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars. formats are supported. Please note that not all of the supported formats have been tested, there are a lot of them and some are quite obscure.

You may notice that Terragen's TER terrain file format (.ter) is listed in the supported formats. However we recommend that you use a Heightfield Load nodeA 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. to load TG terrains, because that uses TG's native file loading.

DEMs often come as a collection of files. If you're not familiar with the DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars. format you may need to experiment to see which file to open. A reasonable guess often seems to be to choose the largest file.

Georeferencing settings are only available in the Professional edition. However the correct size for the DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars. will still be calculated based on georeferencing if needed. Without the georeferencing settings the position of the DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars. will be controlled by the Heightfield Shader the Geog heightfieldA heightmap or heightfield is an array of height values, usually in a grid which describe the height at specific points in a defined area.

When you use a georeferenced DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars. and the Georeference parameterA parameter is an individual setting in a node parameter view which controls some aspect of the node. is checked it will be placed at the correct position on the planet. However accuracy falls away as you move away from the origin of the planet, which corresponds to 0° latitude, 0° longitude or the Prime Meridian at the Equator. To ensure the best accuracy it's suggested that you move the planet origin to the area you're interested in. It's easy to do this. Let's say you've loaded a DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars. and it's georeferenced. We'll move the planet origin so that it's at the southwest corner of the DEMDEM stands for Digital Elevation Model (or Map). A DEM is similar to a heightfield. DEMs are normally generated from real world measurements of a planet's surface, for example Earth or Mars.. Follow these steps:

  1. Click the copy/paste button (clipboard icon) at right of the SW corner lat long parameterA parameter is an individual setting in a node parameter view which controls some aspect of the node..
  2. Choose "Copy coordinates" from the menu which pops up. This will copy the lat/long values from both text fields at the same time.

  3. Open the parameterA parameter is an individual setting in a node parameter view which controls some aspect of the node. view for the Planet 01 nodeA 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. (the default planet object). You can find this in the Objects nodeA 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. list or double click on the nodeA 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.

  4. Paste the values into the planet's Lat long at apex parameterA parameter is an individual setting in a node parameter view which controls some aspect of the node.. You should use the copy/paste button for this again. Click the button and choose "Paste coordinates".

Those steps move the planet origin to the area you're interested and should ensure the best results.
