How to Make Projection of Sphere Surface Powerpoint

In this post, I will build objects that announced spherical, using PowerPoint 3D and fill effects. Like a lot of these posts, in that location are some PowerPoint "secrets" that need to be accounted for.

NOTE: This post is about the 3D drawing tools that take been available in PowerPoint for several years. It is not most the capability to import 3D models that has recently been introduced; there is no capability to actually create these new 3D models in PowerPoint.

Spheres

The bones process is to draw a circle and add a 3D result:

• Create a 2 inch circle (I use this specific measurement to brand the 3D step a little easier).  Remove the outline and fill up with a solid color. Tip: hold down Shift when y'all describe an Oval to constrain the object to a circumvolve. Also, employ the Size/Position pane to go the dimension right.
• Next, in the Format Shape/3-D Format pane, add together a Bevel/Top. Choose the Circle choice and set up the Elevation and Width to 72 pts (ane inch, the radius of the circle). Here are the circumvolve, the "sphere," and the 3d Format for the object:

This "cross department" diagram of the object shows the effect of the 3D settings:

You can, of grade, employ whatsoever measurements you similar.  Since object sizes are measured in inches and the bevels are measured in points, you will have to practice a piffling arithmetic.  Another irritation is that resizing the sphere does non change the bevel dimensions; you volition have to manually change the Height and Width of the Bevel appropriately (sigh).

I selected the Warm Matte Cloth option in theFormat Shape/3-D Format for the sphere. You can experiment with otherTextile options for different effects; here are a few of the options:

Lighting Bending and Lighting can too exist adjusted:

Textures and "Planets"

You can add texture to a sphere by using Fill/Picture or texture and selecting one of the built-in textures; here are a couple of examples:

You can besides utilise Fill up/Gradient; here are two preset gradients:

NOTE: These preset gradient options are no longer available in recent versions of PowerPoint – you volition have to experiment with Gradient Fill to get like results.

Textures and other images tin can also be added to the sphere using Fill and the Flick choice. I take described the procedure in earlier posts; briefly, here'southward how:

• Re-size/crop the image to the aforementioned size as the object to be filled (the sphere).
• Copy the image; this puts it on the clipboard.
• Fill the object using the Picture or texture option, choosing the Clipboard as a source.

NOTE: Run into this post for a lot more detail on Filling Shapes with Pictures.

Here's an case using a "water" image:

The original sphere is filled using the square "patch" shown. Of course, you can fill a circumvolve first and and so apply the 3D Bevel upshot.

You can use other images including maps. Hither are some examples:

Here's an example using part of a map of our moon; I used the Matte Textile:

You can find interestingfictional planet maps; here's one from http://freebitmaps.blogspot.com/:

Text on Spheres

Calculation text to a "sphere" requires some experimentation. First, we blazon a text graphic symbol directly into a circle, and and so employ the 3d effect:

As you can see from the rotated view of the issue, the text remains "apartment.".

The text as well remains flat when a text box is grouped with the circle:

Filling a sphere with a background and the text character via Fill/Picture../Clipboard (equally we did with the textures, etc., above) has a foreign issue:

When the text/background object is used to fill the sphere, it is converted to an image. We can show the reason for the result to a higher place by converting the text/background object explicitly (copying and Past Special/png):

The first object above is the motion-picture show conversion – every bit you can see it is larger than the original object.  I'one thousand not sure why, only I think it has to do with assumptions about the text box, To work effectually the problem, Crop the picture (the second version above) before filling the sphere. The rotated version shows the result with the text befitting to the sphere. Whew!

Puddle Assurance

As you might wait from the previous sections, using Film Fill up is the almost reliable method to create objects with more complex fills, including the pool balls.

For the viii-brawl, brainstorm with a black square containing the white circle and numeral. Use the picture fill technique to fill the sphere:

I changed the Material to Night Edge for a shinier look. Of course, this is simply a half sphere equally shown past the rotated version. To gear up this, use a Bottom/Circle bevel with same dimensions every bit before. Here's the result:

The 10-ball is created the same mode with the stripe added to the image used as fill:

I used an ivory color for the groundwork – white tends to launder out. Of class, you tin can experiment with Fabric and Lighting to get the appearance y'all want.

More "Secrets"

These secrets may be helpful equally yous experiment with these techniques,

Distortion – This experiment shows that the image is actually "projected" onto the sphere from the front, rather than wrapped around it. I used a checkerboard as the prototype:

The front end view shows that the image is non wrapped. When the sphere is rotated, you lot can see how the epitome is stretched around the sphere (the ruby-red line separates the Top and Bottom bevels). The make full is distorted; this is visible when the sphere is rotated. The golf ball case below shows this event:

NOTE: the "earth" in a higher place doesn't appear to have this problem (note Due north America in the 2d example. The reason is that the image is distorted (a map projection). Lucky.

"Dorsum" Image – The fill appears on the Top bevel and you can't separately fill the Bottom bevel. And so what does the "back" of the sphere look like?  The images below respond this question:

As y'all can see, the "back" is also difficult to low-cal.

Shape Effects – Many of the shape furnishings don't apply properly to 3D objects, especially when they are rotated; here are some examples:

This gives you a chance to create some of these effects by hand; here's an example using a separate semi-transparent Oval with a Soft border:

Artifacts – You may see artifacts on rotated objects like the light patches on these objects:

These are because the fill (a picture) is slightly smaller than needed to fill the object. This can be corrected using the Offsets in the Fill pane (fix to -1 or -2 per centum until the artifact disappears).

Blitheness

Often, PowerPoint features are not well integrated with other features – the 3D tools are no exception. The Shape effects (shadow, etc.) mentioned higher up are an case of this.

There is too an issue with animation; here's an example:

As you can see the reflections and shadows on the ball "curl" with the ball – since these features are non role of the brawl just are a result of the static lighting source, this is incorrect.

NOTE: This mail service on vehicles shows how to create a rolling object. Briefly, a motion path is combined with a spin and the path distance is gear up to a multiple (π) of the diameter of the object to avert "slipping." The Smoothen offset/finish option for the motion path is zeroed.

You can ameliorate this past using ii split up objects to represent the ball – the brawl rolls simply the reflections do non:

Here are the two objects:

The commencement object is fabricated like the other examples – a solid circle with the appropriate Bevels; the color is calorie-free grayness with 67% transparency and the material is Clear. The 2nd object is a "flat" (no 3D) version of a pool brawl.

in the animation, the transparent object is positioned In Forepart of the brawl. The objects have identical motion paths but the transparent object does not Spin.
