We have organized a talk on Unity game engine.
Unity is a fully integrated development engine
for the creation of interactive 3D content. There are many games created using Unity like Shadowgun,
ZombieVille, Rochard and many more.
Date: 31st October 2012
Time: 3:30-5 pm
Venue: Classroom 205, KReSIT Bldg, Dept of CSE, IIT Bombay

Talk outline:
General technical overview of the product to show how to produce a project
that can be exported to devices such as smart phones, PC, the Web etc.
Presenters will show how quickly you can get up to speed with Unity and
start creating games whether for prototyping as an artist or a complete
game for programmers. They would also provide more details on the company
and show some examples of their customers.

Presenters:
Ken Noland is an accomplished video game developer and has been working
professionally in the video game industry for over a decade. He has worked
on more than 10 shipped titles on consoles and PC, including the BAFTA
award winning F1 series. Prior to working for Unity, Ken has worked at
some large studios, including Sony, Codemasters, and Foundation 9. He came
to Unity in April of 2012 and has been working as a Field Engineer,
assisting other developers in the development of their games.

Nick Jovic started his career as an industrial designer but his focus was
well and truly shifted when introduced to 3D computer animation in 1993.
From a career, which included designing toys and electronic music products
Nick then entered the 3D animation production world of video games, film,
TV and motion capture. Following seven years in 3D production Nick
transitioned into Technical Sales Consulting and Business Development
working for software technology companies including Alias, Autodesk and
Image Metrics. Nick is currently responsible for Unity Technologies
business development and sales in Europe, Middle East and India.

Blender Workshop at DJ Sanghvi College of Engg. on 5th & 6th October

Rikin, Ronak, Roma, Pooja, Harmit, Sameer, Sarika,
Arun, Amit, Nitin and Sneha....The Blender team

The Blender workshop at Dwarkadas J. Sanghvi College Of Engineering was conducted by the Blender team at Project OSCAR. Along with Sameer Sahasrabudhe, Nitin Ayer, Sneha Deorukhkar, Arun Nair, Pooja Bhawar, Amit Vengurlekar, Sarika Shivsharan, Pankaja Date, students of DJS Roma Dave, Rikin Desai, Ronak Mehta, Harmit Patel were also the volunteers.

It was a two day workshop. As per the schedule on first day workshop begin at 1:30pm and it ended at 5:30 pm, 72 students were present. Second day of the workshop begin at 9:30 am and it ended at 5:00 pm, 67 students attended the second day of the workshop.

We decided to teach them the basics of 3D Modeling, Material, Lighting, Animation and Game Engine. To teach the Blender User Interface we used Blender Video tutorials which have been made for Spoken tutorial Project. Spoken tutorial session was less interactive and feedback for the session was mix. Other sessions were live hands on practice conducted by Nitin, Sneha and Arun.

In Modeling, Animation and Game engine session separate exercise were also assigned. Modeling exercise was chess pawn model, Animation exercise was coin flip animation and in Game engine six different games were given as exercise, one to each student.

Before the animation session we showed Big Buck Bunny short film made in Blender, which actually shows power and capability of the Blender Software.

After the end of the second day’s session we showed animation of Distillation Column and 3D models of Physics, chemical lab Instruments from Project OSCAR repository and animations, which shows how Blender can also be used for e-learning purposes and content development.

Some snapshots from the sesions:


Nitin's session on modeling

Sneha's session on Animation Process and Basics of Animation in Blender.
Arun's session on Basics of Game Engine
and physics in Blender was well appreciated!!

Visualization Winners.
In 3D visualization exercise participants were given the top view and side view of a model and asked to draw 3D view of it.
Below are the models which were different from the general reply of the participants.

Single Replacement reaction animation

Hello Everyone,

I am making animation of the single displacement reaction experiment. It's a school level experiment for Student of 6th to 8th standard.

This experiment is the reaction between Iron(Fe) and Copper Sulphate Solution (CuSO4).

In the experiment Iron nail is dropped in the solution of copper Sulphate in Beaker, after sometime when we remove the Iron nail from the solution the color of the nail changes to reddish orange color.
Experiment Setup

3D models which are used in this animation are available on Project OSCAR 3D model Repository.
http://oscar.iitb.ac.in/blenderrepository.do

I have append the 3D models in a new blend file.
I have used the Basic arrangement for the animation which contains a table and plane as back ground and a plane as emitter for the light source.
In animation I have done camera animation and key frame animation to move Iron nail.

Below is the final camera animation.

Glass Objects in Cycles

Hello Everyone,

After doing some materials in cycles we thought now it should go fine.
A new problem came while doing glass material in cycles.
Amit has model Petri dish in Blender it was first render Blender Render engine.
Reference Image
Blender Render

But problem occur when he was doing material in cycles render engine.
The material looks like opaque glass.

The same problem had occurred earlier when I was doing Cycles material of Reagent bottle and cap.
That time I thought it was because of some error in  modeling and remodel the cap again and the problem solved.

Petri dish I checked the model again exported the models in other file deleted material than redone them again but the output was same.

But when I was learning Blender back 2009 that time I had one problem regarding face normal and how it can be solved by doing Ctrl + N key to realigned all the normals in one general direction.
And this did the trick.
After the correction
Final render after correction

The vertex normals and face normals decide how the direction of lights fall upon the face and how the surface material reacts to the light rays.
Its basic of the class 10th science. about ray refection and refraction when light rays hits a surface.
