You can use the Mesh.isInFrustum method for that.

You can get the planes you need to pass to this function from scene.frustumPlanes if the scene has been rendered at least once, or from Frustum.GetPlanes(camera.getTransformationMatrix()).

It should be accurate, but it’s based on the bounding box of the mesh, we don’t check all the triangles one by one (it would be far too slow to do that for every meshes on every frame).
