Colours – part 04. Mix the colours!

                Welcome to the fourth discussion on the ‘Colours!‘. The topic is getting so exciting and I am very much enjoying it. I am sure you are enjoying the series too, aren’t you?

                Before going ahead, let’s take a quick recap of the first three posts we talked earlier. In the first post, we talked about our relative sensory system, due to which we can see. In the second post we discussed how we ‘see’. How the light emitted from the source gets converted into a brain signal. And further in the third post we met Mr. Light, talked how the ‘Electro-Magnetic Radiations’ of different wavelengths are ‘seen’ as different colours to us. Now today, we will be taking the topic ahead.

                So we now know that, our eyes has three types of ‘Cone’ cells that works as receptors of three wavelength rays. These three wavelengths are seen as ‘Red‘, ‘Green‘, and ‘Blueish‘ in colour. In our eye retina,  the count of such cones is about 2,50,000. Continue reading


Colours – Part 03 (more light on colours)

Since last two posts, we have established a good tempo and talking about Colours! Right? Yesterday, I was compiling all the notes for this post and was sorting topics. And while doing that, I was sort of thinking to ask my doubts to some one who can answer me well. While thinking about that I started dreaming of a meeting with such a one. I immediately called him and asked for his appointment and to my surprise he agreed. And you know what? Today, We have that very spacial guest with us.
‘Mr. Light’ himself. Yes The Great Mr. LIGHT HIMSELF! Ta Da!
Me: Hello Sir!
Mr. L: Hi Mahesh, how are you?
Me: I’m Great! Its my pleasure to see you. And how do you do, sir!
Mr. L: Pretty straightforward. But Mahesh, I am afraid that I have very short time for discussion now. I have to go to my friends birthday. Her name is twinkle. In next 15 seconds I have to reach there. So ask it quickly.
Me: OK, OK. Sir. I will ask you as fast as possible! I was discussing with my friends about how do we ‘see’. Can you describe us, how do we humans see colours? We would love if, you will put some light on that.
Mr. L: OK Time’s up. I need to go now. I will talk with you later! Till then why don’t you google about that your self? Hmm?
And suddenly a big flash of light crossed over my head and then… Continue reading

Talk on Colours – Part02

Hello everyone,

We were talking about a very very wonderful subject – the colours – since the last post. Now we will continue our discussion further.

So, the question arrived earlier was – How do we actually see?
 For us to see anything, it needs at-least these four things.
  1. A light source
  2. An object to look at
  3. The Eye and …
  4. (We will talk about the 4th in just a minute)
The first thing needed is a light source, from which some amount of light is emitted.

Secondly, an object (of course!) to look at has to be there. Continue reading

Colours, wishlisted topic


Colours! What a great and beautiful topic to discuss about. I am feeling really joyful to announce that for next few days we will be talking about such a wonderful topic.

We all know the importance of colours. Colours play a very significant role in our day to day life. Colour is the basic and most primary form of our knowledge of the world that surrounds us. Because of the colours we percept or interpret our environment. Colours are the very alphabets of one of our most prominent senses, the vision. Sight is the most vital sensory system among the five. And with colours we ‘see’, we communicate, we interact, we learn and we do all our activities.

The topic ‘Colour‘ has got both, the scientific side as well as the creative. Of course we are more interested in the creative side, where Continue reading

CG Training

I am in process of updating my blog. In 2003 and 2004, my 2 articles on 3d computer graphics, were published in local Marathi news paper (called ‘सकाळ’). I received huge response and replies from readers. Few more articles are about to be published very soon. So, I am going to add several 3d Graphics related training material on the blog in conjunction with the paper articles, in next few months. The sequence and selection of the training topics, will be based on public and reader’s replies, comments and feedback.

The topics will mainly include 3d Computer graphics, animation project handling, 3d software ‘blender’ training materials.

English Version of my first article – 18 Nov 2003

 Following is the English version of my first article, originally published in ‘Sakal’ Daily News paper, Pune, on 18 Nov 2003, in Marathi. The translation is done by my wife ‘Shruti’. I decided to post this English translation, after I received few responses from some readers and friends, asking for the same. Please leave your comments and suggestions.

Computer Graphics – 3d Animation

About the 3D animation sector of computer graphics, which has made huge economical and industrial revolution all over the world, and which has become a big source of knowledge and earnings, for many artists…

‘The lion king’, ‘Tarzan’, ‘Toy story’, ‘Tom & Jerry’, ‘The Mummy’, ‘Star Wars’, ‘Jurassic park’…. the list is end-less, it goes on and on. What was behind all these movies that influenced the audience so much? Just one thing and that was excellent efforts put forth by the artists. In above all the examples one thing that is common is CG (Computer graphics). Using this CG, impossible things are made possible. In today’s age of ‘IT’ this is one of the most powerful medium that has reached up to the common man. Off course, this technology is not used just for entertainment purpose, but also in the fields of education, engineering, internet, medical, advertisements, case-studies and game developments.

कॉम्प्युटर ग्राफिक्स, थ्रीडी अॅनिमेशन

कॉम्प्युटर ग्राफिक्स, थ्रीडी कॉम्प्युटर ग्राफिक्सचा (थ्रीडीसीजी) वापर कुठे आणि कसा होऊ शकतो, हा प्रश्नच आता कदाचित विचित्र ठरेल. कारण गेल्या काही वर्षांपासून थ्रीडी मॉडेलिंग व अॅनिमेशन करणारी सॉफ्टवेअर्सही पूर्वीपेक्षा अनेक बाबतीत विकसित व अधिकाधिक प्रगल्भ झाली आहेत, अनेक नवी सोपी टूल्स व संकल्पना शोधल्या गेल्या आहेत. त्यामुळे अशा सॉफ्टवेअर्सचा वापर अमर्यादपणे कुठल्याही क्षेत्रासाठी केला जात आहे.

आजमितीला अनेक मोठे वाहन उद्योग, कारखाने व त्यांना सेव पुरवणारे लघुउद्योग इत्यादींना त्यांनी केलेल्या उत्पादनाची तसेच कारखान्याची जाहिरात करण्यासाठी व तांत्रिक माहिती प्रसिद्ध करण्यासाठी विविध माध्यमांची गरज असते. यासाठी माहितीपत्रके, आलेख, व्हिडिओ शूटिंग इत्यादी माध्यमांचा वापर व्यापक आहे; पण गेल्या काही वर्षांपासून थ्रीडीसीजी व अॅनिमेशनचा वापर करण्याकडे या कंपन्यांचा काल वाढत आहे. अॅनिमेशन तंत्रामुळे अशी माहिती ग्राहकांपर्यंत चांगल्या पद्धतीने पोचू शकते. या तंत्रातील अचूकता, वास्तववादीपणा व उच्च तंत्रज्ञान इत्यादी गोष्टींमुळे बऱ्याच कंपन्या तांत्रिक अभ्यास करण्यासाठी व प्रसारमाध्यम म्हणून अॅनिमेशन तंत्र अवलंबून घेण्याच्या विचारात आहेत.
