Would it be possible to add a hide matrixcommand in a future patch? I want to use multiple large matrices, but seeing as there is currently no way to hide them, they slow the game down a huge amount. Even when they're out of camera range or behind the camera, they still slow the game down. Surely this could be accelerated by hiding them?

Anyone else think this would be useful?

Yep, most definitely.

Until that day comes, you could store the matrix point heights into a memblock, and delete/recreate the matrix as needed.

You'll have to try it out to check that it is fast enough for you of course

warning, create a matrix is slow
I made a matrix editor, and it save all in one file ( height + tile's texture ) => to load a matrix, I need ~8-10 seconds

Hmmm, sounds like hide matrix is the only real solution then. Maybe it'll be implemented eventually.

i'd stick away from Matrix altogether and use the new Vector commands to build your own patch matrix

I haven't got even the slightest clue as to what those vector commands do, but I understand they're quite powerful. I'm good with maths, so I should be able to grasp them if there's a FAQ somewhere or a technical doc about them. Any ideas?

I'd like to know more about all these vector commands myself, let me go rtfm...

FAQ would be nice though if anyone knows where???

Seems a bit odd to add loads of new commands and not have any documentation with them. There must be a FAQ somewhere. Anyone know?

just read through all these:-

http://www.flipcode.com/geometry/

It may not be explicitly for DBpro, but if you don't know what a vector is I doubt you could use the commands. Also after reading them you will most probably see how intuitive and useful some of the vector commands are.

I do understand vector theory, but I dont understand
how these new functions could replace the matrix system.
I use matrix's when I want an easy way to read the ground altitude, and becose I dont know the math behind it.
If I did know the math to calculate the ground alitude at
a given position on a X mesh, I'd rather use a mesh generated from a standalone modelling app.

It only takes a fraction of a sec to run update matrix, so why not store your matrix tile & height data in either an array or memblock and update it as the camera moves?

I'm confused as to why you would create absolutely gigantic matrixes - it really is very easy for most purposes to have much smaller ones and dynamicaly shuffle them, surely ?

Dont know whether you've tried a through test, but update matrix is very slow. It's perfectly possible to use the shift matrix commands to make a matrix scroll, but not if you want to change the map geometry. Besides, its so much slower and more complex to leave the player centered in the world and move everything else, rather than just move the player.

I don't think he was talking about moving everything in the world - just create and position each matrix when it is in view, and delete it when it isn't - sort of like a tiling system.

I haven't tried to check the speed of update matrix, so I'll take your word for its speed

no no. that was my suggestion. im the original poster! but i take your point. some people swear by moving the whole world though and leaving the player centered. makes no sense to me!

I haven't used vector commands yet, but I may have to as I have a similar multiple large matrix problem. That said a simple "hide matrix" command WOULD fix my problem instantly, surely it wouldn't be hard to implement, I always saw it as a strange thing to miss out
