I'm writing a wrapper for the Go language for horde, and I want to make sure I understand these two calls: h3dGetNodeTransmats and h3dSetNodeTransMat In h3dGetNodeTransmats, the matrix is defined as Code: const float ** relMat , a pointer to a pointer, while h3dSetNodeTransMat is simply Code: const float * mat4x4 a pointer to an array, correct?Why the difference, and am I right in understanding that in all instances the underlying data structure is simply a array with 16 elements? |

h3dGetNodeTransMats returns a pointer to the internal matrix (which is a float array), thats why it is a pointer to a pointer. In h3dSetNodeTransmat the given 16 float array values will be copied. |
