turned out that I was dereferencing a pointer in a wrong way
with static array it was just:
glBufferData(GL_ARRAY_BUFFER,x,buffer,GL_STATIC_DR AW);
and with dynamic should be:
glBufferData(GL_ARRAY_BUFFER,x,@buffer^[0],GL_STATIC_DRAW);
where 'buffer' is a pointer for that array type.
ps: it liiveees!!

there is no way the compiler would change the layout for dynamic vs static that would break the compatibilty of the two. my guess is that you are miscalculating the size some where and the data isn't making it to the final destination. Edit:guess Iwas too slow, so you got it, looks good.

Not sure if it's solved but I want to make a comment about record alignment. In the engine I wrote and used in the 2nd. PGD Challenge I didn't use records to store data that is used with OpenGL; I use vectors (ARRAY) instead. For example, to store xyz points I used something like:
To access to each axis I use the CONST (i.e. Point[COOR_X], etc). This way I can use the "v" functions without alignment problems.Code:CONST COOR_X = 0; COOR_Y = 1; COOR_Z = 2; TYPE Vector3D = ARRAY [0..2] OF glFloat;
No signature provided yet.
yeah it works alright now
I have a bunch of classes now, should I worry about writing destructors for them or memory will be freed autimatically when app terminates?
when it comes to classes whatever you create you must destroy. you should get heap trace up and running if you don't already. check the output file often to check mem leaks as you go along. also make sure to free up any opengl stuff in your destructors.
ok, thanks. list of leaks is so long that it doesn't fit on the screen
