Haptic holes and surface irregularities

Daniel from H3D.org proposed a solution that might help me in my problem with haptic fallthrough. I can eliminate backface culling by setting solid parameter to false. This will force both sides of model to be rendered.

The x3d data I have is based on the conversion from OBJ to 3DS to X3D. Hence there might be some discrepancies that lead to the irregularities.

I am planning to write a C++ program to directly convert OBJ to X3D. In this way, I can test if the fallthrough is due to the 3DS to X3D conversion.

The OBJ dataset works fine on the haptic viewer example provided by OpenHaptics.

Next, I would need to test the chainmail node provided by Thomas Earnest on my model. H3D currently employs a simple coordinate deformer to respond to any interaction to the surface of the model. I aim to test:

  • chainmail
  • spring mass
  • FEM (maybe)

Unity or Blasphemy

The foundation of one's belief should be based on the need for peace, joy and harmony. One's belief should focus on the positives and not the negatives. No pun intended but Unity is the best policy!

The values of today's society ought to reflect on the destined progress that goes beyond our differences and divisions based on our belief systems. The progress of the mind and attitude that accepts other people as they are, understands rather than tolerates. Isolating and imposing one's values would not bring people together but it would harbour frictions and rebelious motives.

To believe something would not mean a thing if it doesn't come from the heart. It would be foolish to pretend in order to fit in. Be true to ourselves. People can impose but at the end of the day, it will be seen as foolishness.

A shared–celebration should be about unity and not a threat to the 'holier than thou'–s. Where will it lead to… I believe that God is NOT a hateful god!

Besides, there are other pressing issues that need more attention… Focus the energy into helping others who are in great need and stop trying to fix something which has already proven to be positive.

Sorry if I've ranted quite a bit… but read the following…

Ulamas want kongsi raya celebrations reviewed

IPOH: Ulamas attending a conference here want several practices such as the “kongsi raya” celebrations and open houses reviewed to ensure that they do not contradict Islamic laws.

Ulama Conference 2006 working committee chairman Datuk Seri Harussani Zakaria said this was necessary because the National Fatwa Committee had decided that celebrating the festivals of other religions could erode the faith of Muslims and could lead to blasphemy.

“This matter (the Fatwa Committee’s decision), however, is still in the written form and has yet to be forwarded to the Government for action,” he said at the close of the conference yesterday.

The conference also came up with 22 other resolutions, which would be presented to the Sultan of Perak, state government, Federal Government and the Council of Rulers.

Harussani, who is also the Perak Mufti, said the resolutions passed included asking all state Fatwa Councils to set up their respective action committee specifically to respond to views put forward by practitioners of liberalism and pluralism, which attack the faith of Muslims.

The Government was also urged to set up a monitoring body made up of academicians and ulamas to stop the spread of liberal Islamic thinking, especially through the Internet.

“I’m also made to understand that followers of liberal Islamic thinking are waiting for this resolution so that they can draw up a new strategy to counter it,” said Harussani.

The conference also proposed that a dialogue be held involving various groups, including followers of liberal Islamic thinking and other religions, to correct misconceptions about Islam and to understand the views of the other faiths. – Bernama
