void transformPoint3D(float matrix4x4[], float point3D[], float result3D[])
Transform the given 3D point with the given 4x4 matrix (thus, treating the non-present fourth component of the point as being 1.0), and write the result into the given result array.

Arrays.fill(result3D, 0.0f);
for (int r = 0; r < 3; r++) {
 for (int c = 0; c < 3; c++) {
 int index = c * 4 + r;
 float m = matrix4x4[index];
 result3D[r] += m * point3D[c];
 int index = 3 * 4 + r;
