Mac Software For Orthographic Projections

Begin by introducing the concept of orthographic projections to your learner. Start with an example—you can use the one in the background—before moving into the definition. Ask your learner: why do we need orthographic drawings (multi-views) in addition to a 3D drawing of an object? What does an orthographic drawing show that a 3D drawing does not?
Discuss with your learner how to make an orthographic drawing. Make sure to introduce the top, front, and right side views, and show them a simple example drawing such as the one in the background. Have your learner physically look at the object from different views—look at the object from above, from the right, and from the front.
Sample Questions: How do you think the top, front, and right side views relate to each other? What is each view showing? How would you draw this?
Once your learner is comfortable with the idea of orthographic drawings, it’s time to start drawing! Choose a solid, simple, geometric object for their very first drawing.
Suggestions: a book, a block of soap, solid toy building blocks.
When your learner is finished drawing, have them show you the drawing and talk you through how they drew it. Ask your learner: what would they do if the object was hollow inside? How would they draw that? Introduce the idea of hidden lines to your learner, and how they help show parts of an object that cannot be directly seen.
Sample Questions: Why do you think hidden lines are important? How would we add hidden lines to your drawing, assuming that the object is hollow? What are some objects you can think of that would need hidden lines in their drawings?
After discussing hidden lines with your learner, give them a slightly more challenging object to draw that would require hidden lines.
Suggestions: knife block, toilet paper roll, water bottle.
Challenge: If your learner is up to something more challenging, have them select a more complicated object to draw. Before drawing, have them thoroughly inspect the object, or even take it apart if possible.
Ask Your Learner: How would you draw angles? How can you make sure the top view and front view match? What was drawing this object like, compared to the previous ones?

The Orthographic projection is a commonly used projection by cartographers because it closely resembles the world as we know it exists – a three-dimensional sphere (sorry “Flat Earthers”). However, when MAPublisher displays the world in the Orthographic projection, it will still draw any points, lines or polygons that fall beyond the perspective’s horizon. This can create a “hollow Earth” or see-through effect that would cause confusion to the map reader.

Orthographic projection can also be used to render shadow maps, or render orthographic views of a 3D model for practical reasons: an architect for example may need to produce blueprints from the 3D model of a house or building designed in a CAD software.

Orthographic projection can also be used to render shadow maps, or render orthographic views of a 3D model for practical reasons: an architect for example may need to produce blueprints from the 3D model of a house or building designed in a CAD software.

Further confusion may arise depending on the order of the artwork within the layers, as some features that should be on the far side of the Earth may appear on top of features on the near side of the Earth. In order to prevent these inaccuracies, we need to remove the data beyond the horizon before transforming the data to the Orthographic projection. The following workflow is one example of how to overcome this limitation. It can be easily adapted for any orthographic projection with a custom latitude of origin and/or central meridian.

Step 1: Plot Your Centre Point

OpenSong for Mac OS X v.1.7.0 OpenSong is a free, open-source software application created to manage lyrics, chords, lead sheets, overheads, computer projection, and more. OpenSong releases are available for Microsoft Windows, Mac OSX, and Linux operating systems.

Import your world dataset and ensure the MAP View is in WGS84 (or you can use the world.mif file from the MAPublisher Tutorial Data folder).

Next, decide where you want the final orthographic map to be focused on. In this example, our focal point is 70°N, 100°E. Create a point layer, and plot your centre point using the MAP Point Plotter tool.

Step 2: Project to Azimuthal Equidistant Projection

Reproject the map to Azimuthal Equidistant (with a sphere-based datum). To do so, go to the MAP Views panel > Edit Map View. Enable Perform Coordinate System Transformation and click the No Coordinate System Specified hyperlink.

Under the Projected>World category, find Lambert Azimuthal Equidistant (Sphere), meter and click the Copy Object button to begin editing a copy of the existing Lambert Azimuthal Equidistant (Sphere), meter coordinate system.

Side Note – Why start with the Azimuthal Equidistant projection?

The straight-line distance between the central point on the map to any other point is the same as the straight-line distance between the two points along the earth’s surface.

Furthermore, you must use the ‘Sphere’ version of the Lambert Azimuthal Equidistant projection, because the radius is equal in all directions. The other version of the projection uses an ellipsoid datum which would require more complex formulas to solve the buffer distance in Step 3.

Next On the Definition tab, set the Central Meridian to 100, and the Latitude of Origin to 70. You may rename the custom projection on the Identification tab if you wish to reuse it later. Click OK and apply the projection.

Step 3: Create the Horizon Line

Create the horizon line from your custom centre point. Next, add a buffer of 10,002.5 km (see note below) around your focal point.

Curious about where the buffer value comes from?

Given that we know:
Earth’s radius using Authalic Sphere is 6,371,007m
The formula for the circumference of a sphere = 2πr
The distance from the focal point to the horizon in the Azimuthal Equidistant projection = 1/4 of Earth’s circumference = C × 1/4

We can first determine the circumference by:
= 2πr
= 2 × π × 6,371,007
= 40,010,000 m

Now that we know Earth’s circumference, we can determine the distance to the horizon by:
= C × 1/4
= 40,010,000 × 1/4
= 10,002,500 m or 10,002.5 km

Step 4: Convert Your Custom Horizon Line

Convert the resulting circle with four Bezier curve points to polylines using MAPublisher’s path utilities tool Convert Beziers to polylines. This is your horizon line.

Step 5: Back to WGS84 and Editing the Horizon line

Import another copy of your world file. If necessary, transform it to WGS84 and drag your horizon line into this MAP View. You can also hide or remove the Lambert Azimuthal Equidistant MAP View.
