Archive: Creating 3D Objects in PowerPoint

banner.jpg

I’ve written a lot of posts involving PowerPoint 3-D drawing tools, so I’ve decided to list some of the more useful ones in this archive.

NOTE: This post is about the 3-D drawing tools that were introduced in PowerPoint 2007. In 2018, the ability to embed standard format 3-D models was introduced; the 2018 release does not include tools to actually create these kinds of 3-D objects in PowerPoint.

The 2007 3-D tools are limited and frustrating – I hope the techniques developed in these posts will help you get the most (such as it is) out of them.

The list is in reverse chronological order. Generally, the posts include links to earlier posts that may explain techniques more thoroughly.

Putting Text INTO Pictures embedding text within pictures adds a lot of impact. To make this convincing, you might have to make the text match the perspective of the picture – this post shows you how to do this with 3-D tools (and some effort).

PowerPoint People – 3D Robots

banner

This is another post on adding characters to your presentations to help tell and sell your story. There’s an earlier series on simple cartoons (basic figures, characters and expressions) and one on using Lego people.

Since robots are not confined to a human shape, you can create a variety of characters and “occupations.” And, if you think robots can’t have personalities, remember Hal, Bender and WALL-E.

Here’s an example of a humanoid robot figure created in PowerPoint:

turdMy posts on PowerPoint “3d” are exercises in using tools in ways for which they were never intended.  In addition, PowerPoint 3d is poorly integrated with other PowerPoint drawing features (e.g., shadows) and poorly documented (e.g., 3d rotations and lighting). So, expect serious limitations and disappointments if you venture here without guidance.

I created this robot using techniques I have used before making 3d blocks, buildings, vehicles and other things. Basically, it involves assembling separate objects, each with a “Parallel” rotation, to achieve a “3d” construction.

As usual, I started with front and side views of the robot. Only standard PowerPoint shapes are used; no freehand drawing required:

r2

Here are some notes:

  • For clarity, I used different outline colors for the body/head, the legs and the arms.
  • I strongly recommend using Snap to Grid with a rather  coarse grid setting (I used 0.05 in.) to make it easier to draw and align the shapes.
  • Drawing Guides are used to align the parts in the two views. If these alignments are wrong, it will be obvious when you try to assemble the 3d construction.
  • The “chest” is a Union of two Rectangles; I’ll try to make it clear why I used Union rather than Group later.
  • The”hand” is a Chord shape and two Rectangles.

Next, I made a temporary copy of the front view and rotated it 90 degrees. Using the side view, the rotated front view and drawing guides I drew several “cross sections” of the robot that will help align the parts in the 3d construction. Here’s how I drew the cross section at the top of the “hip” section (outlined in yellow); it includes the outline of the disc that connects the hip with the chest section.

r3.png

It’s easier to draw these sections one at a time than to draw an entire top view.

Here are the sections and where they will fit in the 3d construction:

r4.png

The sections that will locate the arms and legs are simply copied from the side view.

Here’s the process for the construction of the body and head:

  • The parts and yellow “sections” are rotated (Parallel/Isometric/Left Down and Right Up) and moved into position to form the outline of the head, chest and hip parts.
  • The circles are rotated and filled to form the discs that connect the parts. 3d Depth is added (72 points per inch).
  • The other parts are filled; Depth is added using the yellow sections as guides.
  • Using the yellow sections as guides, the discs and body parts are moved into position. For example, the first “neck” section is aligned with the head. Then the neck disk is aligned with the circle in the neck section. The section representing the top of the chest is then aligned with the neck disc, allowing the chest to be aligned next. Imagine that you are stacking the parts.
  • Keep the sections “in front” during this step; this keeps them visible and allows easy removal later.

The next step is adding the limbs:

The arm and leg parts are Unioned to form the arm and leg (more about this later). Depth is added to the arm and leg. The rotated yellow sections are aligned with the side of the body allowing the arm and leg to be positioned. The other side is completed using copies of the leg, arm and sections. Even though the “disc” parts are invisible in this view, they establish the relationship between the body parts.

To finish, remove the yellow section objects and color the body parts, adding details as needed:

turd For various reasons, the Material, Lighting and Lighting Angle tools are useless for this project. After considerable experimentation, I recommend the method documented here rather than endless fiddling with combinations that are ultimately faulty.

For the robot coloring, I want front surfaces to be darker and visible side surfaces to be lighter, as if light were coming from the robot’s left. Here’s my method:

  • Since the “lighting” can’t be turned off, I have picked a combination of settings that seem to minimize its effects: Flat material, Contrasting lighting and zero Lighting Angle.
  • To control the color of each component, select Fill and Outline colors to create dark and light surfaces. In particular, use dark gray fill and light gray outline on components that “face the front” and the opposite for components that face the side; here are the chest and an arm:

  • This is the reason that the limbs are Unions, not Groups – if they were Grouped, extraneous outlines would appear when the Outline color is added.

By the way, here are some ideas to give the robot expressions (you can also survey various toon robots for inspiration):

r10

You can “pose” the robot; here’s a walking version:

Here’s how the walking robot is constructed:

The limbs are constructed and positioned as before. If the orientation is not as shown, the 3d rotation will be incorrect.

TIP: The orientation of a Union is determined by the first object selected. In these examples, the red-outlined object is selected first:

For the first Union operation the top rectangle (red) is selected first, followed by the other (blue) rectangles. The result has a vertical orientation (note the “rotation handle”); the 3d rotation works as expected. For the second Union the red rectangle is selected first; note that it has been rotated. The result of the Union has a rotated orientation and the 3d rotation is different.

Of course, robots don’t have to be humanoid and use legs for locomotion:

I used the same techniques as before; here are the construction details:

The “hand” is made by subtracting a rounded rectangle from the arm/hand object.

Once you’ve made a few of these, you can position the parts and add depth “by eye” and avoid some of the tedious steps, at least for fairly simple robots. That’s how I made this example:

  • The positioning and depth were created by eye without using yellow “sections” as guides.
  • The right arm is a copy of the left arm, Flipped twice.
  • The eye shapes have a smaller depth than the head; here’s a close up:

r16.png

TIP: Selecting an object within a group can be tricky, especially in 3d; the image above shows that the head is selected and the eye is selected within the group (faint outline). Use the Selection Pane if you have trouble.

Here are the details on constructing a robot with another form of locomotion:

r17

  • The arms are Line Arcs. You could draw a freehand line using the Curve tool if you’re comfortable with that.
  • The hands are Pie shapes.
  • I used a section (yellow) to help position the legs; the other parts are positioned by eye.
  • The rocket plume is a Triangle with a Gradient Fill.

If you need a villain in your story, try this one:

r18

  • Two parts are made from the outline drawing: the head/chest/shoulder unit and the whole body. Each is Unioned.
  • The two parts are rotated and Depth is added.
  • Material, Fill, Line and lighting are set as before but with darker colors.
  • The two parts and a copy of the smaller part are “stacked” as shown to complete the figure.

Robots are also modeled from nature; here’s an insectoid version:

r19.png

The robot is made using the techniques discussed above except that an additional X-Rotation has been added to the front and back legs. Here’s  what the 3D Rotation looks like for a couple of the legs:

r20.png

The middle leg has the preset Isometric Left Down rotations; the back leg has the X-rotation reduced by 10 degrees. WARNING: Do not use the rotation icons (circled in red) for this; mysterious, undocumented things happen when these are used.

turd I haven’t been able to find adequate documentation on rotations, materials, lighting, etc. If you know some sources, please let me know by adding a comment.

You can exercise your imagination by adding body segments, antennas, stingers, wings, etc., and other coloring. Why not consider other beasts as models for your robots?
