lib3ds2.0 BUG fix

library:    lib3ds 2.0

====================================================

file:         lib3ds_node.c

line:        169

 

original codes:

----------------------------

Lib3dsCameraNode*
lib3ds_node_new_camera(Lib3dsCamera *camera) {
    Lib3dsNode *node = lib3ds_node_new(LIB3DS_NODE_CAMERA);
    Lib3dsCameraNode *n;
   
    assert(camera);
    node = lib3ds_node_new(LIB3DS_NODE_CAMERA);
    strcpy(node->name, camera->name);

    n = (Lib3dsCameraNode*)node;
    lib3ds_track_resize(&n->pos_track, 1);
    lib3ds_vector_copy(n->pos_track.keys[0].value, camera->position);

    lib3ds_track_resize(&n->fov_track, 1);
    n->fov_track.keys[0].value[0] = camera->fov;

    lib3ds_track_resize(&n->roll_track, 1);
    n->roll_track.keys[0].value[0] = camera->roll;

    return n;
}

-----------------------------

 

 

my fixed code:

 

Lib3dsCameraNode*
lib3ds_node_new_camera(Lib3dsCamera *camera) {
    Lib3dsNode *node;
    Lib3dsCameraNode *n;
   
    assert(camera);
    node = lib3ds_node_new(LIB3DS_NODE_CAMERA);
    strcpy(node->name, camera->name);

    n = (Lib3dsCameraNode*)node;
    lib3ds_track_resize(&n->pos_track, 1);
    lib3ds_vector_copy(n->pos_track.keys[0].value, camera->position);

    lib3ds_track_resize(&n->fov_track, 1);
    n->fov_track.keys[0].value[0] = camera->fov;

    lib3ds_track_resize(&n->roll_track, 1);
    n->roll_track.keys[0].value[0] = camera->roll;

    return n;
}
