current modelview matrix makeup

OpenGL OpenGL: Basic Coding

hi if i use the glget command to retreieve the current modelview matrix as a 16x float array, can anyone point me to documentation that shows what data the individual array elements represent. I know it has things like the current, up, right and in/out vectors but i dont know how its organised

thanks for any help

spooky, the basis vectors are in the columns of the matrix.

whats a basis vector, and which of the 4 columns are they in ?

the OpenGL matrices are column major:

|m0 m4 m8 m12|
|m1 m5 m9 m13|
|m2 m6 m10 m14|
|m3 m7 m11 m15|

The glGet function returns a one dimensional array:

[m0, m1, m2, m3, …, m15]
