Summary
POLYDATA is used to transfer 3D polygonal data. The message format is designed based on the POLY DATA format defined in VTK file format and equivalent to VTK's vtkPolyData class.
Message Types
POLYDATA
| Data | Type | Description |
| NPOINTS | uint32 | Number of points |
| PTYPE | uint16 | Data type (see image) |
| POINTS | PTYPE * NPOINTS * 3 | Coordinates of points (P0x, P0y, P0z, P1x, P1y, P1z, ... P(n-1)x, P(n-1)y, P(n-1)z |
| NVERTICES | uint32 | Number of vertices |
| VERTICES | uint32 * ((NPOINTS_0+1) + (NPOINTS_1+1) + (NPOINTS_(N-1)+1)) | array of vertices ((NPOINTS_0, index_0_0, index_0_1, ....), (NPOINTS_1, index_1_0, index_1_1, ....), ..., (NPOINTS_(N-1), index_(N-1)_0, index_(N-1)_1, ....)) |
| NLINES | uint32 | Number of lines |
| LINES | uint32 * ((NPOINTS_0+1) + (NPOINTS_1+1) + (NPOINTS_(N-1)+1)) | array of vertices ((NPOINTS_0, index_0_0, index_0_1, ....), (NPOINTS_1, index_1_0, index_1_1, ....), ..., (NPOINTS_(N-1), index_(N-1)_0, index_(N-1)_1, ....)) |
| NPOLYGONS | uint32 | Number of lines |
| POLYGONS | uint32 * ((NPOINTS_0+1) + (NPOINTS_1+1) + (NPOINTS_(N-1)+1)) | array of vertices ((NPOINTS_0, index_0_0, index_0_1, ....), (NPOINTS_1, index_1_0, index_1_1, ....), ..., (NPOINTS_(N-1), index_(N-1)_0, index_(N-1)_1, ....)) |
| NTRIANGLE_STRIPS | uint32 | Number of lines |
| TRIANGLE_STRIPS | uint32 * ((NPOINTS_0+1) + (NPOINTS_1+1) + (NPOINTS_(N-1)+1)) | array of vertices ((NPOINTS_0, index_0_0, index_0_1, ....), (NPOINTS_1, index_1_0, index_1_1, ....), ..., (NPOINTS_(N-1), index_(N-1)_0, index_(N-1)_1, ....)) |
GET_POLYDATA
| Data | Type | Description |
STT_POLYDATA
| Data | Type | Description |
STP_POLYDATA
| Data | Type | Description |
