Bases: taichi._lib.core.PyScene

set_camera(self, camera)
mesh(self, vertices, indices=None, normals=None, color=(0.5, 0.5, 0.5), per_vertex_color=None, two_sided=False)

Declare a mesh inside the scene.

Parameters

  • vertices – a taichi 3D Vector field, where each element indicate the 3D location of a vertex.

  • indices – a taichi int field of shape (3 * #triangles), which indicate the vertex indices of the triangles. If this is None, then it is assumed that the vertices are already arranged in triangles order.

  • normals – a taichi 3D Vector field, where each element indicate the normal of a vertex. If this is none, normals will be automatically inferred from vertex positions.

  • color – a global color of the mesh as 3 floats representing RGB values. If per_vertex_color is provided, this is ignored.

  • per_vertex_color (Tuple[float]) – a taichi 3D vector field, where each element indicate the RGB color of a vertex.

  • two_sided (bool) – whether or not the triangles should be able to be seen from both sides.

particles(self, centers, radius, color=(0.5, 0.5, 0.5), per_vertex_color=None)

Declare a set of particles within the scene.

Parameters

  • centers – a taichi 3D Vector field, where each element indicate the 3D location of the center of a triangle.

  • color – a global color for the particles as 3 floats representing RGB values. If per_vertex_color is provided, this is ignored.

  • per_vertex_color (Tuple[float]) – a taichi 3D vector field, where each element indicate the RGB color of a particle.

  • two_sided (bool) – whether or not the triangles should be able to be seen from both sides.
