Regular API function


Description Multiplies two transformation matrices. See also the other matrix/transformation functions.
C synopsis simInt simMultiplyMatrices(const simFloat* matrixIn1,const simFloat* matrixIn2,simFloat* matrixOut)
C parameters
matrixIn1: the first input matrix
matrixIn2: the second input matrix
matrixOut: the output matrix (the result of the multiplication: matrixIn1*matrixIn2).
A transformation matrix contains 12 values (the last row (0,0,0,1) is omitted):
The x-axis of the orientation component is (matrix[0],matrix[4],matrix[8])
The y-axis of the orientation component is (matrix[1],matrix[5],matrix[9])
The z-axis of the orientation component is (matrix[2],matrix[6],matrix[10])
The position component is (matrix[3],matrix[7],matrix[11])
C return value
-1 if operation was not successful. In a future release, a more differentiated return value might be available
Lua synopsis table_12 resultMatrix=simMultiplyMatrices(table_12 matrixIn1,table_12 matrixIn2)
Lua parameters
Same as C-function
Lua return values
resultMatrix: the result matrix (a table containing 12 values (the last row (0,0,0,1) is omitted)). Table values in Lua are indexed from 1, not 0!
