streamlit-stl 0.0.5

A Streamlit component to display 3D models in STL format

Streamlit STL Display Component

A Streamlit component to display STL files.

Installation

This component requires access to write files to the temporary directory.

pip install streamlit_stl

Example

Look at the example for a streamlit Web App:

The original STL file is from Printables.

Usage

Display from file paths

import streamlit as st
from streamlit_stl import stl_from_file

success = stl_from_file(
    file_path=path_to_conf,          # Path to the STL file
    color='#FF9900',                 # Color of the STL file (hexadecimal value)
    material='material',             # Material of the STL file ('material', 'flat', or 'wireframe')
    auto_rotate=True,                # Enable auto-rotation of the STL model
    opacity=1,                       # Opacity of the STL model (0 to 1)
    shininess=100,                   # How shiny the specular highlight is, when using the 'material' style.
    cam_v_angle=60,                  # Vertical angle (in degrees) of the camera
    cam_h_angle=-90,                 # Horizontal angle (in degrees) of the camera
    cam_distance=None,               # Distance of the camera from the object (defaults to 3x bounding box size)
    height=500,                      # Height of the viewer frame
    max_view_distance=1000,          # Maximum viewing distance for the camera
    key=None                         # Streamlit component key
)

Display from file text

import streamlit as st
from streamlit_stl import stl_from_text

file_input = st.file_uploader("Or upload an STL file", type=["stl"])

if file_input is not None:
    success = stl_from_text(
        text=file_input.getvalue(),  # Content of the STL file as text
        color='#FF9900',             # Color of the STL file (hexadecimal value)
        material='material',         # Material of the STL file ('material', 'flat', or 'wireframe')
        auto_rotate=True,            # Enable auto-rotation of the STL model
        opacity=1,                   # Opacity of the STL model (0 to 1)
        shininess=100,               # How shiny the specular highlight is, when using the 'material' style.
        cam_v_angle=60,              # Vertical angle (in degrees) of the camera
        cam_h_angle=-90,             # Horizontal angle (in degrees) of the camera
        cam_distance=None,           # Distance of the camera from the object (defaults to 3x bounding box size)
        height=500,                  # Height of the viewer frame
        max_view_distance=1000,      # Maximum viewing distance for the camera
        key=None                     # Streamlit component key
    )

The functions return a boolean value indicating if the program was able to write and read the files.

The 'material' style is the default style, it uses the Phong shading model from Three.js.
