Yes there is, people here make me glad every time they release something into this community!
Because of this, it's always a pleasure to post source

Purebasic / OgreMagic for PureBasic
« on: August 26, 2007 »
Hi PureBasic users
Just want to tell that , OgreMagic is supporting PureBasic now. So you can easlly use OgreMagic Library with your favorite basic language.
Here is a small test programe.

Freebasic / Re: SDL question
« on: July 17, 2007 »my best and dear friend shocky.
Just I am wonder , why he still concentrate all the time on software rendering stuff and you do always ignore directX. I know you have a laptop which has no much hardware acceleration , but even if so DirectX still offer you a lot.
So my best advice for you to use DirectX or using OpeGL.
By the way if you want me to make some simple functions such as my OgreMagic for you , I will do it for you.

Thanks shocky very much for your explaination. , it is really helpful , but i am still stuck.
i will show you my code , hope you can help me.
1- have a Box structure which holds a 4 points represinting the rectangle and halfWidth , halfHeight.
2- given a center coordinate of the rectangle (CX ,CY) and the rotation angle THETA.
here is my function that calculte the final 4 point of the rectabgle. but it does not work as expected.

Nice p01.
It is really easy , and you open my mind for new idea , which is you did not have to interpolate the angle instead you calculate the angle between each interpolated point and the previous one.

Relsoft:
Your spline code is very helpful and very close to my coding style. So thank you very much for your help.
Just I want an other thing , suppose you have a ship space that follows this spline ,so how to control the rotation of the ship to insure that it face the next point, I.E if our ship face to left hand and the next point is in the right direction so can you adjust your update routine to allow the ship smoothly change the rotation to face to next point?

Hi shocky
Nice effect , but is not that chessfield scrolling that same as that one in IROSP4.bas except that it is vertically here ?

Yes shocky , I want that the pass is a strait line and at the same time at the control points the change in path is smooth.
But I think this is impossible , so I will use relsoft Catmull-Rom Spline.
I want that routine to allow my Library users to define a path that control the translation and rotation and scaling and may be the color of sprite in the animation scene. So first I was searching for good translation spline then I will modify it suit my needs.

Freebasic / Re: good spline tutorial
« on: July 07, 2007 »Ok Jim, i have tested the Catmull-Rom Spline that posted by relsoft and found that it is very useful, and did not see any Cubic splines.
Only the Littile thing about the Catmull-Rom Spline is that the path is a curve not a strait line between each points.

Freebasic / Re: good spline tutorial
« on: July 06, 2007 »ok , I have changed my mind , so I will use a Linear interpolated instead of spline , but still have a small problem , I want my Object to smooth move when it reachs to control points.
For Example. suppose you have 10 points , p1,p2,p3 .......... so on.
first we will interpolat btween P1 and p2 and when object reachs to p2 we will interpolat btween P2 and p3 , and so on.
the problem is when the object reachs to p2 it will change the path from P1-p2 to P2-P3 in non smooth change .
any idea to solve this problem please ?
