Experiments on HTML 5 canvas

Like I mentioned in my tweets before about being excited about the new Chrome Javascript engine and its speed and how google folks were trying to port Quake2 on it... it got me the initial push to try experimenting on it I have written a Bezier curve evaluation functionality (not using direct Bezier draw method) on this, user can create curves by clicking on the canvas, on the side the blending functions are plotted too, its quite fast to my surprise :) Give it a try here: http://www.freewebs.com/rishiparkhe/beziercurve.html OR on blog http://rishikeshparkhe.com/this-program-demonstrates-working-of/

Laser scanner experiments (again)

After some break, I am back at the laser scanner experiments. Today I tried to make a new housing for the laser assembly so that I can place it properly in relationship with the camera. I am planning to create a base platform which has screw holes at known positions so that I can screw the camera and laser housing. That would reduce my initial setup time quite a bit. All this activity was with the intention to increase the accuracy than previous setup.

Stuck in reverse (Laser scanner)

Well, I am getting a bit of progress on the 3D viewer and physics stuff but, it is rather slow. Part of the things that I wanted to try is to reverse engineer a real object and load it in a simulated Wind Tunnel (Physics engine) to run a basic test on that. This has lead me to create a very basic laser scanner at home. It’s very primitive at this point of time and I do not intend to go deep into developing the one giving best results, its too early.

Physics engine roadblock

I guess I should have seen this coming before (day before). After writing some bits and pieces of math and particle physics code, I realised that the visualiser application is not capable enough to test things. There is a dire need for overloaded key handling and mouse based entity editing and navigation. Also I cannot go on adding buttons for each and every function, this calls for a JRuby interpreter on the visualiser. Need to spend some time on the GUI front to get it up to the mark next.

Casual programming... Physics engine from scratch

In the vacation time, I have decided to write a physics engine of my own from scratch as a hobby project. It would be a good brain workout after regular work. At the end I would learn a few things.
