TriangleListPrimitive
Represents a primitive that consists of a set of triangles or a surface tiled with triangles.
Parent Data Structure
TriangleListPrimitive appears in the SceneEntity message data structure.
Data Structure
| Field | Type | Description |
|---|---|---|
| pose | pose | Origin of the triangles relative to the reference coordinate frame |
| points | Point3[] | Vertices for the triangles, interpreted as a list of triplets (0-1-2, 3-4-5, ...) |
| color | color | Solid color for the entire shape. Either color or colors must be provided. |
| colors | Color[] | Color for each vertex (if specified, must be the same length as points). Either color or colors must be provided. |
| indices | uint32[] | Indices into the points and colors attribute arrays, which can be used to avoid duplicating attribute data. |
indices
If omitted or empty, no indices are used. This default behavior is equivalent to specifying [0, 1, ..., N-1] for the indices (where N is the number of points provided).
Reference Implementation
The visualization data structure is framework-independent and can be implemented using any supported message encoding:
| Encoding | Data Structure |
|---|---|
| ROS 1 | foxglove_msgs/TriangleListPrimitive |
| ROS 2 | foxglove_msgs/msg/TriangleListPrimitive |
| JSON | foxglove.TriangleListPrimitive |
| Protobuf | foxglove.TriangleListPrimitive |
| FlatBuffers | foxglove.TriangleListPrimitive |
| OMG IDL | foxglove::TriangleListPrimitive |
You must use the data structure names specified above for the visualization to recognize the data structure.
