Texturing using Blender


Terms:
  • Material:
    • Defines the optical properties of an object: its color and whether it is dull or shiny. 
  • Texture:
    • A pattern that breaks up the uniform appearance of the material.
    • A property OF the material
    • Can't have a texture without a material

Blender:
For no particular reason other than a few trial and error attempts with a few different modelling applications I decided to use blender as my 3D modelling software of choice. I've never done any kind of 3D modelling before so learning some of the absolute basics took awhile to get my head around. 

 After watching a load of tutorials I have a 2 different techniques that are basically the same, one just requires more work in Blender and the other more work in Unity. 

 Technique 1:
This is the first way that I tried where I created the textures inside Blender and applied them to the box within the application. I then imported the fbx file to Unity and for the most part the textures crossed the platform reasonably okay however there were some faces that didn't work which I assume is due to slack UV unwrapping or something on the Blender side. This technique is slightly more complex because it requires better knowledge Blender to execute well. I still don't really understand how the different lighting modes work etc etc so a lot seems to be just trial and error.

Technique 2:
This was just an experiment on my behalf but I found that if I unwrapped the box on Blender side and applied some basic materials to each face, when I imported to Unity I had a materials array where I could individually assign materials to the faces. This way it meant that I had more flexibility within Unity and could just use the imported images to create textures. From what I can tell I think if I did the first technique properly I would of been able to do this aswell but I'm not totally sure.

I think when it comes to texturing hands it will have to be done via Technique 1 as I don't think Unity will have the capability of texturing something that complex. I will need to do some more tinkering with Blender so that I will feel more confident when it comes to modelling the hands. It will just take a little bit of practice till I become more confident with the software itself.

Texturing Hands

Texturing the 3D Hands The purpose of texturing the box was so that eventually I could move on to texturing realistic hands.  The first issue I had was that Leap Motion export their prefabs in the ASCII format of .fbx (i'm guessing because it's human readable?) and Blender doesn't allow importing of ASCII file so I had to convert to a Binary file using an external application.  After importing it into Blender I realized there was something called Armature which I hadn't heard of before and as I started reading I figured it would help to look a little bit into how animation works so I could understand the Leap Motion documentation a little bit better. Leap Motion uses something called Skeletal Animation for their hand prefabs. When using this method we split the character object (in this case hands) into two parts, the skin/mesh and the interconnected bones/rig. The bones are connected in a hierarchy so that when you move for example the tip of the fin...

Day 2

Image
Sam's Demo To start today, as per Holger's request I captured an admittedly very amateur screen cast of Sam's Demo. I wasn't quite sure how to best show the different functions of the program. After a few failures this was the best I could come up with: Will have to add video capturing skills to the list of things that will (hopefully) improve throughout the duration of this student ship. I'm not sure how to get four hands up and going currently. Creating a trial leap hands project Today I decided to start by attempting to create a basic program that could render two hands as an attempt to get my head around the software a little bit.  I first downloaded a bunch of stuff: Leap Orion (The SDK for leap) Leap Core Assets (Package with basic functionality) Leap Graphic Renderer (Aims to create a system that allows you to to treat a collection of objects as a group) I followed a set up tutorial found here: https://developer.leapmotion.com/do...

5th of Dec Update

Haven't updated in a while because I haven't really made any major achievements, everything has been very gradual in growing my understanding with the Leap API as well as how Sam's demo actually works. I've been focusing the last few days on how Leap works, from how to access any leap data within a script to detecting hands using the HandModels[] from the current Frame. I had a slight play around with the concept of four hands simply by duplicating the LeapController and HandModels twice over and position them in a way as to replicate four hands. Movement is that where both the left hand controls both hands on the left side and vice versa with the right. This was a good way to visualise the task and see the gaps in why this technique wouldn't work. My current challenge is to replicate the mirroring from Sam's demo. Now that I understand the code better I can see that the way that Sam has implemented it is no longer possible with the new Orion API. He mir...
