So I rigged the character model of myself. The rigging for the model I think was good but the weight mapping isn’t, I can never get the hang of it. That said I think I did enough to prevent major distortion. It’s most obvious on the shoulders, though. On the up side, I decided to have a go at making a walk cycle for the character and I am happy with the results. there is no skipping or jumping in the animation and flows pretty smoothly at a good speed.
To end of the first semester of this year I had to complete a time constrained workshop. This is where you go in to uni in the morning, pick one of 3 briefs and then complete the brief of your choice to the best of your ability within 8 hours. The brief I decided to go for was a destruction derby environment as I believed these where my stronger points in modeling and also lets me showcase a lot of different techniques. After 8 hours I had completed the brief with what I consider a half decent outcome with the time given. I was able to show my use of motion paths as well as bending tilting and modifying the object associated with that motion path in the ways that I wanted. I also used expressions for the wheels, Blend shapes for deforming the cars and bump maps on the ground texture. Here is a final render from what I had achieved. The rendering was not part of the assessment and was rendered after the workshop was done.
For our second assignment I was to create an adventure game within android studio. The game itself could be all text based and only required simple buttons for movement from one room to the next. For me this seemed to simple and very similar to the text adventure I created last year in C++ (view post here). The purpose of this assignment is to show would could create the same program in different languages. I wanted to push myself and advance forward with my adventure game so I decided to stay within the boundaries of the assignment while at the same time creating some more advanced features. The main thing I wanted to do within the game is to get the player some movement so that the user could move the player around the screen. I managed to achieve this by using runnable functions for moving the player around and I also created a player controller to allow the user to move the player where they wanted. This was a lot harder then i first thought as android studio is not a game engine so the player controllers are a lot more finicky to created then in actual game engines. This also proved difficult when I wanted to test for collisions within the game as there is no On Collide function within android studio. To mimic an On collide function I used the rect function. This is more commonly used for drawing shapes on the screen. I used it to test for if one rect would intersect with another. Once I had programmed this it then allows the user to pick up and drop items where they please. For the final outcome of my game I was able to create an interactive game where the user has a lot more control then they would if there were to just hop from room to room with the press of a button. Essentially I was able to turn a 1 dimensional game into a 2 dimensional game. Here are some screen shots and a short video of me explaining my program in a little more detail.
So after a few weeks of powering through I have managed to achieve a finished product. The entire video is only 1 minute long but I am very proud of what I have achieved. I used many techniques and software through out the possess of making this animation, all of which is explained in more detail in my previous posts.
Bellow is also a fill dome render for my scene although the output you will see is rectangular and fish eyed. The video input into the dome will be square and the final outcome will be a full 360 view of the enviroment.
For my roller coaster scene I was required to create a character with a skeleton and morphing facial features. This character is meant to be a second passenger in the carriage with the viewer. But for mine I thought it would be more effective if I have my character on the outside of my fish tank looking in and tapping on the glass. The textures of the character are a simple change of colour within the hypershade. I used blend shapes to morph the face into different expressions.
In my roller coasters journey around the track I wanted there to be a fish that the diver passes and follows around. I took some reference images of the internet for a face on and side on view of a gold fish that I could model from. I created it with a cartoon style and started from a flat plane and extruded and manipulated vertices to I have the shape of the fish I wanted. To texture and paint the fish I imported the fish model from Maya over to Mudbox. I upped the models subdivisions from level 1 to level 5 and then added texture to the model as well as mold some eyes onto the model. From there I painted the model to the colours I wanted. I then exported the models normal map, ambient occlusion map and colour map from the level 5 model to apply back onto the level 1 model.
For the fish I wanted to give it some basic movement so rigged a skeleton and made the fish move via the use of expressions. I used a SIN formula to make two of the fish’s joints move from side to side
One main decision I decided the change was that the diver carriage would suspended below the track instead of sitting on top so the passenger could look down when near the top of the tank. There is an image below of the Diver and the track to give reference to my explanation.
The diver as well as most of the assets in the final scene where created in their own scene to then be imported into the final scene. All the Textures for the Diver where created using UV maps. The glass on the diver is just a plain blinn texture with transparency and a light blue tint.
I used expressions on the wheels and rear propeller to show the diver is rolling along the track instead of sliding. The speeds of these wheels are based on the U value of the diver’s motion path that goes around the track. This is so when the diver speeds up or slows down that the wheels rotation speed with do the same.
When I moved on from my original idea of the justice league. I realised that I needed to choose an environment that would be close together and dense as to give the illusion that the view is passing a lot of different objects when there are actually passing the same object from different angles. With this in mind I decided to go with the idea of a fish tank, where the passenger would ride around in a diver instead of a carriage. This also gives me a refined area to build a roller coaster in.
Some of the first things I made for the fish tank was some fake plants and coral. The fake sea plants where created using a basic stem shape and then duplicating the leaves all the way of the plant. There are 4 different kinds of plants I have created, all in different colours. Each colour plant is identically the same as far as shape and size are concerned but each one has been textured differently and rotated so each one looks different.
There are 3 different pieces of coral in the fish tank each a different colour. Each on was created from a simple cuboid and different faces extruded out. To finish it off I smoothed each one of them off to make each one look like coral. Although each coral was a different shape and size I used the same texture on each on and just changed the colour in Photoshop to keep the texture consistency the same.
I also used a bump map on each of these to give a sense of depth within the object itself. Also because I used the same texture for each piece of coral I was able to use the same bump map for each one.
The only other objects I included in the scene was a bridge and castle just to give it that fish tank feel. I made these out of simple shapes and textured those using UV maps. These objects also have bump maps applied to them
Because I have used smoothing in a lot of my objects the UV textures have been stretched to accommodate this but these stretch marks are not noticeable when riding past objects at high speeds.
Although my roller coaster is within a fish tank I still needed to create some environment on the outside of the tank. I created a simple room with some basic object just as lamps, sofas, a window ect.
For My second assignment in my modeling module I was to create a roller coaster scene where the final render would take the view on a ride around the track. We also needed to have a unique theme that there view would experience and that we could also reflect in the way the roller coaster was built.
My first idea was for my theme to be based around the justice league and the main 7 super heroes that make up the league. The idea was to have a city environment and for the characteristics of the track to change relating to the super hero as the ride went on. As I started to make the city and the assets I would use for my scene i came to realize that the idea I had in my head was just far to big for me to fulfill in the time frame given. Although I liked, the idea the more objects I built the less I was enjoying the idea and decided to think of new ideas. Below is the scene I made before changing my idea.
One of the first assignments of the new year at university was to make a model of the solar system. I went through different steps and trial an error ti decide what the best size would be for all the planets and the scale of distance. After a while it quickly became obvious that the scale of distance was going to be an issue as Neptune would have been so far out in the animation that that you wouldn’t have been able to see it. Bellow is a rendered image of the solar system where all the planets are to scale of each other (the sun is 2.5x smaller then it should be) and distance between each planet is to scale (the distance from the sun is not to scale). It is apparent that the 4 planets closest to the sun are too close together for the model to look visually appealing. Also there are no moons around any of the planets and the moons would be colliding with other planets. Because of this I decided to not scale distance with this solar system.
From there I needed to choose a planet and have it do one complete rotation of around the sun with all the other planets rotating around the sun there respected amount of times. I decided to use Saturn. This is so the outer planets look like they are moving, at the same time that the planets closest to the sun wont be going too fast for the viewer to see.
I had to create a spread sheet with all my workings for planet size and distance. This consists of all the relevant information for the planets and moons i will be creating. It seems complicated but by using this i was able to calculate all the figures i needed to key frame to correct rotation after 1800 frames in a 30 FPS video.
With all of this i managed to produce a final outcome that i am fairly happy with. I manipulated the mash on the sun too look like it is moving in time and the earth and mars have an atmospheric glow. Here is a video of my final product.
|IMPROVEMENTS!|
After coming back after a few weeks focusing on other work I decided to change how my sun was textured. Before my sun was animated by warping the mesh of the sun so make it look like the texture was moving. Instead I added a fractal texture to the ambient light field of the sun texture. I key framed the rotational twist of the fractal layer and the texture is self but in opposite directions. This allows for the sun to stay in one uniform state and overall give a better affect then i originally conceived.
