Re: [Playerstage-developers] graphics3d interface mods

[Radu B. R. <ru...@cs...>]

Okay then. Time to make a new interface! :)

I think it would be safe to begin with:
#define PLAYER_3DPOINTCLOUD_MAX_POINTS ... (what would be an appropriate value here?)
#define PLAYER_3DPOINTCLOUD_DATA_STATE 1
typedef struct player_3dpointcloud_data
{
   uint32_t points_count;
   player_point_3d_t points[PLAYER_3DPOINTCLOUD_MAX_POINTS];
   uint32_t points_colors_count;
   player_color_t colors[PLAYER_3DPOINTCLOUD_MAX_POINTS];
} player_3dpointcloud_data_t;

#define PLAYER_3DPOINTCLOUD_GET_GEOM_REQ 1
typedef struct player_3dpointcloud_geom
{
   player_pose3d_t pose;
   // or, as Raymond suggested in a previous e-mail (with PLAYER_3DPOINTCLOUD_MAX_POSES
   // defined earlier somewhere):
   //
   // uint32_t poses_count;
   // player_pose3d_t poses[PLAYER_3DPOINTCLOUD_MAX_POSES];
}

Please feel free to commend, fix or add additional structures/definitions.

PS. Brian, you can remove the graphics3d patch from SF then. Thanks.

Best,
