Hi Experts,
This may sound stupidity.....anyhow....let me ask the doubt, Even though shell is just a scripting language, can anyone tell me, whether web pages can be created with embedding some concepts.

I'm just curious about the amount of time it takes you to get to work in the morning and whether you drive a car, ride a bike, walk or take public transportation.
On a typical day I drive 10-15 minutes from my house to my work location followed by a 10 walk from the parking lot (car park to my... (12 Replies)
Hi Guys
I am currently running AIX 5.3 technology level 6 on a 570, but want to go up to level 9.
However I am struggling to find on IBM's website the new features that it brings in, along with the commands for these new features.
Can any one help me with this?
Thanks (7 Replies)

DESCRIPTION
Sweep an arbitrary contour along a helical path.
The axis of the helix lies along the modeling coordinate z-axis.
An affine transform can be applied as the contour is swept. For most ordinary usage, the affines should be given as NULL.
The "startXform[][]" is an affine matrix applied to the contour to deform the contour. Thus, "startXform" of the form
| cos sin 0 |
| -sin cos 0 |
will rotate the contour (in the plane of the contour), while
| 1 0 tx |
| 0 1 ty |
will translate the contour, and
| sx 0 0 |
| 0 sy 0 |
scales along the two axes of the contour. In particular, note that
| 1 0 0 |
| 0 1 0 |
is the identity matrix.
The "dXformdTheta[][]" is a differential affine matrix that is integrated while the contour is extruded. Note that this affine matrix
lives in the tangent space, and so it should have the form of a generator. Thus, dx/dt's of the form
| 0 r 0 |
| -r 0 0 |
rotate the the contour as it is extruded (r == 0 implies no rotation, r == 2*PI implies that the contour is rotated once, etc.), while
| 0 0 tx |
| 0 0 ty |
translates the contour, and
| sx 0 0 |
| 0 sy 0 |
scales it. In particular, note that
| 0 0 0 |
| 0 0 0 |
is the identity matrix -- i.e. the derivatives are zero, and therefore the integral is a constant.
