Vuer

TriMesh

Overview

TriMesh creates custom 3D meshes from numpy arrays, giving you complete control over vertices and faces for procedural generation, real-time updates, and scientific visualization.

Basic Usage

import numpy as np
from vuer import Vuer, VuerSession
from vuer.schemas import DefaultScene, TriMesh, OrbitControls

# Create a simple triangle
vertices = np.array([
    [0, 0, 0],
    [1, 0, 0],
    [0.5, 1, 0],
], dtype=np.float32)
faces = np.array([[0, 1, 2]], dtype=np.int32)

app = Vuer()

@app.spawn(start=True)
async def main(sess: VuerSession):
    sess.set @ DefaultScene(
        TriMesh(
            key="triangle",
            vertices=vertices,
            faces=faces,
            color="red"
        ),
        bgChildren=[
            OrbitControls(key="OrbitControls")
        ],
    )

    await sess.forever()

Key Parameters

Parameter Type Default Description
vertices ndarray - (N, 3) float32 array of XYZ coordinates
faces ndarray - (M, 3) uint32 array of triangle indices
colors ndarray - (N, 3 or 4) array of per-vertex colors
uv ndarray - (N, 2) array of UV texture coordinates
