|Creating scenery for Micro Flight|
Flight supports three types of scenery:
based scenerey, with automatic texture
scenery, with single object and texture
imported scenery with tile based object files.
tile based scenery is the most common scenery type in
Micro Flight, it is defined by a large bitmap which holds
the DEM ( Digital Elevation Model ) , and another which
holds the objects information.
texture for this type of scenery is generated by
interpolating between textures which are associated with
elevation and producing a smooth blending between them.
benefit of this type of scenery is that it can use very
few textures to produce a seamless photorealistic view
which is related to the elevation data, an example can be
seen in this image:
photorealistic scenery is based upon a large aerial
photo, the textures are extracted directly from this
photograph, the elevations are taken from an ascii text
file and the objects can be built using a single data
benfit of this type of scenery is that it can reproduce a
small well defined area with a good accuracy, the
disadvantage is that the texture is big and take a lot of
memory and disk space.
type of scenery typically takes just a small portion of
the map as the texture file cannot be as large as the
elevation map, such a scenery can been seen in the
scenery is designed to make use of the extensive data
available on the web at the USGS download site.
import process requires using the popular 3DEM software made by Visualization Software LLC
by Richard Horne, the software can be downloaded here.
The process of
importing this type of scenery to Micro Flight is simple:
- Download the
DEM file from the USGS server.
- Load the file
into 3DEM using "Load terrain model".
- From 3DEM
select "Save terrain matrix" as a
binary signed integer file.
- Take the
files created (*.bin and *.hdr) and put them into
an empty directory.
- Take a few
terrain textures and place inside the new scenery
- Run Micro
Flight and select the new scenery.
The benfit of
using Micro Flight with this type of ecenery is
enourmous, you can navigate real USGS scenery and fly
inside it, making Micro Flight an essential tool for
anyone working with this type of data.
An example of this
type of scenery can been seen in the following image:
