Чтобы создать прямоугольную треугольную призму в Blender, вы можете использовать различные методы. Вот несколько подходов с примерами кода:

Метод 1. Использование сценариев Python:

import bpy
import bmesh
from mathutils import Vector
# Create a new mesh object
mesh = bpy.data.meshes.new("TriangularPrism")
obj = bpy.data.objects.new("TriangularPrism", mesh)
# Link the object to the scene
scene = bpy.context.scene
scene.collection.objects.link(obj)
# Create a bmesh object and add vertices
bm = bmesh.new()
bm_verts = [Vector((0, 0, 0)),
            Vector((1, 0, 0)),
            Vector((0, 1, 0)),
            Vector((0, 0, 1)),
            Vector((1, 0, 1)),
            Vector((0, 1, 1))]
for v in bm_verts:
    bm.verts.new(v)
# Create faces by connecting vertices
bm.faces.new([bm.verts[i] for i in [0, 1, 2]])
bm.faces.new([bm.verts[i] for i in [3, 4, 5]])
bm.faces.new([bm.verts[i] for i in [0, 1, 4, 3]])
bm.faces.new([bm.verts[i] for i in [1, 2, 5, 4]])
bm.faces.new([bm.verts[i] for i in [0, 2, 5, 3]])
# Update the mesh with the bmesh data
bm.to_mesh(mesh)
bm.free()

Метод 2: использование встроенных операторов Blender:

import bpy
# Create vertices
verts = [(0, 0, 0),
         (1, 0, 0),
         (0, 1, 0),
         (0, 0, 1),
         (1, 0, 1),
         (0, 1, 1)]
# Create edges
edges = [(0, 1),
         (1, 4),
         (4, 3),
         (3, 0),
         (1, 2),
         (2, 5),
         (5, 4),
         (2, 0),
         (5, 3)]
# Create faces
faces = [(0, 1, 4, 3),
         (1, 2, 5, 4),
         (0, 2, 5, 3),
         (0, 1, 2),
         (3, 4, 5)]
# Create a mesh object
mesh = bpy.data.meshes.new("TriangularPrism")
mesh.from_pydata(verts, edges, faces)
# Create an object and link it to the scene
obj = bpy.data.objects.new("TriangularPrism", mesh)
scene = bpy.context.scene
scene.collection.objects.link(obj)
