[IdiotEngine] 02: 'Civil War' Spider-Man Lens Modelling

As part of my continued collaboration with JD under the banner of IdiotEngine, I have 3D modelled Spidey's more complex shutter-based lens from 2016's Captain America: Civil War for JD to 3D print. 

This was a fun little modelling project, and is the first time that I've needed to keep in mind the real world dimensions of an object since my final Elements Academy uni project last year. If you'd like to find out more about the methodology behind the creation of this lens 3D model, please scroll down to the bottom of the post.

To figure out the height of the lenses I used a cropped head-only version of the above film still featuring Tom Holland's Spider-Man to estimate the actual height of his lenses (10cm / 3.94"); I did this via a combo of Photoshop guides and research into the average height of a human head (8–9"). This enabled me to model a 1:1 scale version of these unique Spidey lenses within Autodesk MayaTo avoid it looking puffy in reality, the lens model needed to be no more than 1cm thick, but also able to support several layers of overlapping geometry, so I had to find out if JD's da Vinci 1.0 3D printer would be able to print at a small enough scale. 

It turns out that by adjusting the print speed the machine is impressively able to handle minuscule scales of at least a ¼ millimetre, so having each of the nine lens slides created just 1mm thick will be no problem when JD prints it. This also means that if he needs to squish the lenses even thinner, such as half a cm thick, he has plenty of room to do so.

Within Maya itself, the fact that the lens would have no moving parts meant I was able to create each slice of the shutter geometry with its side and inside edges piercing the geometry surrounding it to increase the ease of modelling, and to ensure that there was no chance of unwanted holes within the geometry. Every individual part of the lens began life as a perfectly square polygon plane which I then scaled, stretched, and extruded its leading edge multiple times to create a very low poly version of its future self. 

Adding complexity to this basic shape is where the Multi-Cut Tool came in, I used it to quickly and easily create new edge loops exactly halfway between each polygon edge (Mac: ctrl + shift), which I then carefully dragged using the Move tool to sit along the appropriate edge of the vector art/orthographic I'd created from the guide photo. 

I also used Smooth Preview and Vertex Mode to figure out the correct positioning of each poly edge. Extrude was used again to give each 2D lens plane depth, Reverse Normals was used to sort out the resulting geo, I held down X when using Extrude's move function to snap the base of each lens part to the grid floor, and finally Bevel was vital for the edges of the geo keeping shape when smoothed. When the lenses are due to be 3D printed, I'll permanently Smooth the geo and export both the left & right lenses out as STL_DCE files.

[IdiotEngine] 01: GotG Star-Lord Bag Buckle 3D Modelling

Recently I began working with my friend JD on producing custom 3D models for his up-and-coming, previously one-man props, replicas & custom hero suits company, known as IdiotEngine; best known for its high quality handmade superhero suits and well realised prop reproductions, which are all created with a meticulous eye, as if a love letter to the characters and companies JD loves so dear. 

I recently 3D modelled the Star-Lord sling bag buckle for JD's personal project, for which he's building his own Star-Lord cosplay/costume, complete with helmet, headphones, jacket, 3D prints of Star-Lord's gun, bag buckle & the Infinity Orb, as well as handmade boots, Star-Lord sling bag, and 
custom Sony Walkman.

Having an experienced 3D modeller on the team has begun to allow JD to even further expand upon what he is able to produce, especially in the case of 3D printed objects that would be far too time-consuming for him to sculpt entirely by hand. Of course, having a plain 3D printed object is one thing, but the sizing, sanding, smoothing, painting and in the case of fabric/leather-based props, stitching and weathering of the object is a whole other story. Thankfully, however, JD has had a passion for the handmade since a child, and is hoping to make IdiotEngine an official full-time production in the near future. Next up will be modelling some of the components of Star-Lord's headphones, before moving on to potentially larger builds.

A bigger project for IdiotEngine may likely be 3D modelling Fallout 4's brutal fiery sword weapon, the Shishkebab, for JD to 3D print and do all the rest of the hard work with. I think you'll agree this sounds flaming awesome! sorry, couldn't resist! :L
