Simple question.After DBPro cancelled its updates I wish to have some minor changes which can be made with external plugin imho.Bad thing is that I dont know C++.So I'd like to hire someon who knows it well

Are you planning to sell your plugin then?

All your TGC are belong to us.

@Phaelax
some 3d rendering improvements.
increse speed with instances and vertex data manipulation.

You can't do that in an external plugin unless you write an entirely separate render engine.

I mean only change rendering engine or rather make some new features like matrix1 plugin.
For example this plugin allows users of DBPro to draw the same object multiple times - it uses modified DBProBasic3DDebug.dll ( for version 7.5 )

Exactly
Thus it is a recompilation of a base library rather than an external one. But yeah, I see your point.
As for the vertex data speed-up, have you tried using get vertexdata ptr? That will give you as much of a speedup as you can get in DBPro since all you'll be doing is writing directly to the buffer without any extra function calling overhead or safety checks (unfortunately you will still get the function call overhead from the memory manipulation functions unless you only push 32-bit data, which may also be implemented internally as a function call, I'm not quite sure).

Also, what kind of speed increase to do with instances do you propose?

get vertexdata ptr? I remember this was new in Dbpro 7.3 It is faster than default vertexdata commands?How can I used this?

It gives you a raw pointer to the memory that the vertexdata occupies.
The format of the vertexdata buffer is similar to that of a memblock mesh, but I think that some parts use smaller datatypes than DWORD's in the buffer as opposed to in the memblock (for example the number of vertices is a word I believe).

Is it will be stable to edit vertex position in memory in realtime? And have I use IanM's Matrix Utils for memory editing?Just load object
- lock vertexdata - find vertex data ptr - write DWORD for vertex position for example (with Matrix Utils) - unlock vertexdata ?

As long as you don't write out of bounds of the buffer I don't see why not. You can parse the fvf member (which is at address ptr + 4) to figure out if and where certain vertexdata members are (for example a mesh doesn't necessarily have a color member and so on; if you assume it does you will run into issues with this approach that using the built-in vertexdata functions protect you from).
