Mosquitro Redesign: The Needle

  I spent some time today modifying the head of my mosquito model. After adjusting the lenses so the pole would be pointing outward, the whole shape appeared to nestle more smoothly into the gap designed for it.There was some adjustment needed but these were only a few tweaks. There does appear to be a fair amount more flow, however as the geometry for the eyes runs more in line with the cavity for the head..

  The next big challenge was the port for the mosquito's proboscis, which in the mechanical model would function like a powerful injector. I had a stroke of inspiration that the port would open up like a flower. The mechanisms for this however, might require some thinking as the needle would either push these petals out or they'd open out in preparation for the needle extending..

  The model is quite detailed, so I am planning to look into making a normal map for a simplified model for more full-body shots of the vehicle.

Mosquito Redesign: Working Legs

  I didn't have much success implementing an IK nor getting it to compress, but they say the simplest solution is often the most effective. In the case of my piston the simple solution was to parent each of the pistons with each other, tie them to 'aim' themselves at the opposing hinge and create a few driven keys to mimic the pistons extending and compressing.

  After that it was a simple matter of constraining each of the hinges. and the pistons so they stop at a fixed instance into and out of their sockets. By adding a fifth segment to the leg I am able to extend its reach to a motion window of between 92 and 168 degrees (any more open and the piston will collide with the knee hinge). Which might be one of them ore complicated elements of the model out of the way.

From what has been assembled so far, I think I can easily fit six of the legs into the main body with plenty of room to spare.

Mosquito Redesign: Leg Hydraulics and Industrial Fun

  Much of this afternoon has been spent reworking the leg to make it something more industrial. I've looked into completely redesigning the limb using the hydraulic system idea to give the legs weight and balance. What I've got so far appears to work to a decent degree, even if the geometry might be a little heavy. I'll look into fixing the UVs before the leg is repeated.

  The piston that would appear to keep the leg unbent will use some manner of spline to adjust itself. I'll need to perform some experiments to get a system that can extend the segments - what is on display is the furthest the leg can bend with this but with some clever re-positioning I might be able to extend the leg further. I can also use the freedoms presented by the digital medium to make it easier for the base to compress into the pivot it's connected to, allowing the sections to fold in and extend automatically and the pivots to rotate appropriately. This further tweaking might also allow the lower leg to more easily fold in.

  That still leaves how to fit six of these inside the body. The folding in isn't the most efficient use of space, it could be the legs are arranged diagonally and drop through hatches in the mosquito's underside (which will be fun to build and set up). Only one leg will be worked on until the UVs, bones and controls are set up, which will be reproduced five times.

  Overall, it appears to be quite a flexible setup. The leg bends in the right place, the lower joint provides most of the positional mobility and the foot has full free rotation so it can plant itself flat in a large variety of poses. An IK/FK system could be used for deployment, positioning and resting as one thing that could be implemented are shock-absorbers at the ankle - a simple tube that compresses into the body to give the feeling the machine is bearing weight when its turns its engines off.

It's about ready for the UVs

Mosquito Redesign: Early Stages and Legs

  I'be been thinking for a couple of days now about going back and redesigning one of my old projects. Namely the mosquito craft from one of my first year university projects. This design was ambitious, even back then and the video it came with was somewhat popular so I thought why not go back and rebuild the thing with better creative knowledge, problem solving skills etc.?

   One thing I really wanted to try out in the old design was some form of foot. In the original model I believe they were just spikes due to time pressures. With a better grasp of Maya's rigging and component system I feel confident I can do a proper foot as well as better joints. For fun I could design all kinds of bells and whistles: Brake flaps, redesigned landing gear bays, ailerons, a probe bay, maybe even rotary blades in the wings and a segmented design to allow for full-wing tilting and proper VTOL.

   I've mostly been inspired by the ship designs made by Cloud Imperium for Star Citizen. I tried the game out once during a free weekend and was amazed at all the little animated components the one-man ships had whether it was for doors, maintenance hatches, thrusters, airlocks, you'd think they brought in mechanical engineers to work out all the components. I might not go that far, the mosquito in the sequence primarily concerns landing and takeoff but no lie, it would be fun to try and build some sort of open folding mechanism for the front probe or the landing gear.

   I might keep the hydraulic system. It was quite useful for compacting the legs into the body (all six of them) and this time around I could go an extra step, maybe include the tubes for the hydraulic fluid that could be linked to the model via a spline curve.

  I am definitely going to need some kind of control rig to sort out all the moving parts I already have. It would definitely make accessing the components for animation a lot easier, too.

Infiltrate Exploit Spread: Mosquito Motion Refinement.

    I did some editing on the Mosquito's animations. I'm not sure what happened during encoding to compress the video at the sides the video like this but I suppose it's not too bad as the essentials of what I want ot convey in the video remain in there. The 1920x1080 resolution is still on my computer so at least I have the undistorted version on record.

Infiltrate Exploit Spread: The Mosquito's Arrival

     This animation was rather fun to do, especially the initial approach there the mosquito adjusts itself as it prepares for landing, something helicopters and VTOL jets to to align themselves ready for landing. It took a little tweaking to make sure the corrections didn't look like the pilot was having trouble keeping the craft steady.

    The model's textures are still, unfortunately a work in progress, but after liking the results of the chromed blood vessel tunnel I decided ot investigate doing similar with the legs of the mosquito to reinforce a metallic look. I was also drawn to the idea of a reflective cockpit window though with that oen I am considering toning down the reflectivity to keep the window dark. One advantage though is that I have less that needs being given a texture map

    I also tried tweaking the direction of the light, although I do feel that the initial angle allowed the viewer to see more.

Infiltrate Exploit Spread: Landing Test

    Taking a break from texturing the mosquito I decided to construct the animation parameters for when it lands. The landing impact could probably do with a bit of work but for the most part it seems fine. Though I definitely think I need to refine the "oomph" it delivers when it lands.

Mosquito Development: Mosquito Markings

    While working on the texture map for the mosquito I had an idea to bring it back to the military-themed inspiration - markings. During WWII (and I think it happens now still) bomber and fighter crews marked their kills with tallies of pictographs on the sides of their planes.

   Another thing they marked was rather fun pictures to denote the wing the pilot belonged to, hence 3 and 5. However given the nature of some of the things air force pilots liked to paint on their planes; if I go though with this I think I'll stay clear from such images as saucy ladies or cartoon bugs as it really does not suit the intended sinisterness of the mosquito.

Mosquito Construction: Early Revision

    As I said I would I have remodelled the mosquito and for a couple of hours work I feel I have made considerable progress. In terms of gemoetry all that is left for the fundamentals are the head, legs and the abdomen. I will then mirror the geometry to get what should hopefully be a completed model. I cannot say for sure but the geometry does feel neater than the previous version.

Considering the length of time taken I will put this to the side for now and prioritise on the microbes for a bit.

It seems neater than before...

Mosquito Development: Orthographs

    Taking advantage of render times on a Maya tutorial I decided to work on orthographic designs for my mosquito so that I can get around to building it in Maya over this week. I decided it was important as I estimate this to be the most complicated prop in the animation so I will need to set time aside for building it. I will see later this week if this is enough to build it or if I will need to reduce it to line-art to construct it effectively.

    I went this direction for two reasons: For production art purposes and it allowed me to easily block out the shapes of the thing. The front Orthograph is missing its head but that was so I could work out what the neck was doing.
