Autodesk ReMake – Review

Over the last couple years, we have seen the 3D archaeology community grow at an incredible rate. As awareness for the potential of these tools has grown, I have been asked several times about the best way to get started. Depending on their need, I generally recommended Agisoft PhotoScan as the current standard in archaeology circles. With PhotoScan they can get lots of help, flexibility in subject scale, few limitations, high accuracy, it is relatively easy to use, and it has recently come down in price.

However, to anyone currently looking to get into photogrammetry for interpretive and educational purposes, I have a new recommendation. Autodesk ReMake is perfect for any program that just needs to make a model of an object without investing too much time and money.

Pricing

The professional version of ReMake currently runs at $30 a month or $300 a year. You could compare this to PhotoScan’s regular professional license of $3499, but they are really not related. A more appropriate comparison is to PhotoScan’s standard license which is currently available for one-time fee of $179. As a result, ReMake really does not make financial sense at this level.

However, ReMake has a free or educational license which makes it worth considering. There are features that are available in the full version that are not in these licenses. For example, neither can freely use “Ultra quality” images (though I have not had any issues) and the free version is limited to 50 photos (though you can do an awful lot with 50 photos). For the rest of this post, I will be talking about these two licenses.

Making a Model

If you want to get an idea of what it takes to make a model in PhotoScan, I suggest checking out the guide I assembled here. ReMake simplifies this process immensely. You merely select your photos, name the model, decide if you want their auto crop or smart texture options, and then hit “Start.” As we are working with the free or educational licenses, the program will then upload your photos to a cloud, process them, and then notify you when your model is available to download.

It really is that simple. There are some limited editing options for a finished model, but I have not had much need for them. As you can see, the results are excellent and more than serviceable. Occasionally, I have gotten ReMake to assemble a model that PhotoScan could not figure out.

 

Features/Limitations

For ReMake features and limitations go hand-in-hand. If you are using one of the free licenses then you only have the option of using the cloud for processing your model, you cannot create it on your computer (locally). If you are like me, this is perfect because my computer struggles to do anything while a PhotoScan model is processing. Also, unlike programs such as 123D Catch you still retain full rights to your model.

If you want a fully 3D object in ReMake (one with a completed bottom) then you will have to use a second program to assemble it like Blender or MeshLab. Technically, you can do this in PhotoScan which automatically stitches two models together to create a complete model. In practice, this has been far more finicky so I do not expect to miss it.

Finally, there is no masking option in ReMake. This means that, if your background is not out of focus, you will run into problems. On the other hand, this will cause difficulties in PhotoScan too, though you can overcome them with effort. That being said, the model below turned out pretty well, and this is one that PhotoScan struggles to make sense of.

 

ReMake is a much simpler and more accessible program than PhotoScan. This naturally means that you have less control over your model and you have fewer options. If a model does not turn out well, for example, you do not have the option of spending hours trying to manipulate the program to get a result (which actually appeals to me somewhat). On the other hand, if you have a casual, non scientific project where you just need a model for a demonstration or for printing, it is excellent.

Using Tinkercad And Other Modeling Systems to Contextualize Structures in The Classroom

In last week’s post, I discussed a watermill model that I created as part of my thesis research, this week I will discuss the program I used. Because I am a graduate student and new to modeling, I needed a program that was free and relatively easy for a novice to navigate. The program itself had to allow me to create the model from scratch. This was important because unlike photogrammetry, I wanted to make my model using measurements taken in the field and reconstruct the mill rather than just render it as it stood today.

Once I began working with Tinkercad, the website that I will review today, I realized its educational possibilities. Tinkercad is a free, browser-based CAD program, and is in no way the only option out there. As a former teacher, this program could easily be incorporated into classroom lessons. In my experience creating my watermill model, this is an exceptionally user-friendly, and free site for creating a free-form model and also possesses numerous applications in and out of the classroom.

Tinkercad is part of a family of free apps available from Autodesk 123D, I have not experimented with the other apps, each of them have different applications. There is an app for iPads as well as one that can generate 3D models from photos, much like PhotoScan, though I think PhotoScan is a more intense and professional process, an opinion based on limited experience. Most of the programs and sites I found, which are listed at the end of this post, were not suitable for my project due to requirement of downloading software or that only a short trial membership was available before requiring payment.

A free account with Tinkercad lets you create designs and save them under different projects, allowing for generational designs; it also allows you to create several types of downloadable files of your model that can been uploaded to other sites such as Sketchfab. The resulting file can also be used to print your model either with a personal 3D printer or by a company of your choosing. There are two formats to create designs with, normal or Beta. Beta differentiates mostly in the user interface, allowing the use of keyboard shortcuts, as well as the ability to collaborate with others.

Once an account is set up, the user is free to create projects and then save them to be accessed later. Once the project is created a work plane is displayed, at this point it is imperative that the scale you wish to use is set. In the bottom, right hand corner an edit grid option is displayed, inches and millimeters are your two options. For inches, 39.37 x 39.37 is the largest grid possible and for millimeters a 1000 x1000 grid is the limit. If a larger grid is necessary, this program is not a good option. The grid is easy to use and when scaling an object, the rulers that measure the item as you move it are invaluable.

Though you can create your own objects to use in your model, the provided geometric shapes and the community created objects are very versatile. One of the best features is the ability to use an object as a “hole”, for an example of this I used a cylinder and a sphere to create a ditch in the top of the cylinder. The hole is completed when you group the two objects together.

Shapes are also very easily manipulated. The example I’ve shown here is a pyramid altered into a thin section to make a trowel. Going into the program and manipulating the shapes is the best way to learn to navigate the program. One important feature is the Fit to View Selection this focuses in on the selected shape and helps when working with them. Of course, you can always create your own shape and even import shapes from your computer or other sites. Given a little bit of time and practice manipulating the shapes and holes, custom shapes and objects are easily rendered for specific items.

This program is an exceptional option for use in public education settings. Some possibilities for this program in the classroom I can see are:

  • Having students explore symbols and how to create them
  • Using static objects such as cylinders or boxes and inventing a useful tool
  • Using scale to model an existing item or building
  • Designing an artifact from the past or one of the future

Without creating a full tutorial on how to use this site, I hope I have provided a starting point for anyone interested in modeling. Tinkercad provides a wide assortment of tools and an easy to navigate “sandbox” with the grid system to allow for a large degree of control over your design. In the classroom, students can create their own personal accounts because the program allows for collaboration between users; there is not a download requirement (most schools require permission to download programs, so you can skip the IT department).

This site is most certainly not the only one available to aspiring modelers. Here is a list of others I have found and explored:

 


Elizabeth Chance Campbell is a Master’s student at the University of Central Florida and will be defending her thesis, on an 1866 watermill, in the spring. She worked in a low income middle school for five years where she taught students with learning disabilities before moving to Georgia, where her wife is stationed in the Air Force. She hopes to take her experience as an educator and as an archaeologist to the next level by creating lessons that can be incorporated into classroom settings with students of all levels.
