I was looking at the 3D math matrix commands in DBP last night, but I didn't see any way of pulling information out of a matrix. For example, you can extract the x,y,z, and w variables from a vector4, but I can't find similar matrix commands. I wouldn't mind making a memblock and manually pulling out the data, but I didn't see any "make memblock from matrix" type command either. Any suggestions?

Could you not loop through all the matrix vertices and store them in a memblock. Since you know how many segments the matrix is divided into (you created one in the first place) it should be a simple matter of finding the points and storing the info.

Wildbill, if you're talking about the DB Matrices that make landscapes, then you're on a totally different subject

The matrix I'm talking about is a little bit like a 3x4 array. Using that analogy, how would I access the individual elements of the array?

(Don't tell me how to use arrays!)

Thanks Dmitry,
