This dialog allows the user to export the current terrain and texture in various mesh formats. The terrain can be broken into tiles so that the generated files are smaller. Pressing the ok button allows the straight export, without optimisation of the mesh.
The exported files append a number running sequentially from 1 to the number of tiles in the grid ( running in the x and then y axis ), to the base name. Each tile will have a texture associated with it, using the same numbering system. For example,
base name = "myMesh"
number in X = 2
number in Y = 2
Mesh Type = .X files
Texture file type = jpg
Output will be myMesh1.x and myMesh1.jpg, myMesh2.x and myMesh2.jpg, myMesh3.x and myMesh3.jpg, myMesh4.x and myMesh4.jpg.
Number in X: the number to tiles to separate the terrain into on the x axis.
Number in Y: the number to tiles to separate the terrain into on the y axis.
Samples per tile X: the number of samples to take along the x axis per tile.
Samples per tile Y: the number of samples to take along the y axis per tile.
Total mesh width: the width in mesh ( external co-ordinate system ) units.
Base Name: the name the tiles use to append numbers to for the exported files.
Output folder: the folder the exported files will go into.
Texture file type: select which file type the tile textures will be exported to.
Mesh Type: select the desired output mesh type.
Texture Resolution X and Y: specify the resolution of the texture files per tiles.
Output Normals: place vertex normal information into the exported mesh files, if supported.
Is seamless tile: specify that the edges of the terrain match up, creating an infinite landscape.
Centre on Origin: when unchecked, place the bottom left of the mesh at the origin. When checked place the centre of the mesh at the origin.
The user can also optimise the mesh within Geoscape3d. This can be achieved automatically by pressing the optimise button at the bottom of the dialog.
Edge spacing X and Y: This specifies to keep vertices at regular intervals along the mesh. This means the tiled meshes will join up with one another without noticeable gaps in joins being created by the optimise process.
The navigation of the 3d view is similar in operation to the main editor. You may navigate around the mesh preview using the two camera modes, Free Look and Fixed Rotate. Also, you can move the view to selected positions using the Above, North, East, South and West.
