Quick Overview

Blender is a free and open-source 3D creation suite. It supports the entire 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing and 2D animation pipeline. Blender is a cross-platform application, available for Windows, Linux, and macOS.

Pros

  • Completely free and open-source
  • Comprehensive set of tools for 3D creation
  • Active and supportive community
  • Regular updates and improvements

Cons

  • Steep learning curve for beginners
  • User interface can be complex and overwhelming
  • Some industry-standard features may be less polished compared to commercial alternatives
  • Performance can be slower for very complex scenes compared to some commercial software

Getting Started

To get started with Blender:

  1. Visit the official Blender website: https://www.blender.org/
  2. Download the appropriate version for your operating system
  3. Install Blender on your computer
  4. Launch Blender and familiarize yourself with the interface
  5. Follow beginner tutorials available on the Blender website or YouTube to learn basic operations

For developers interested in contributing to Blender:

  1. Fork the Blender repository on GitHub
  2. Clone your fork: git clone https://github.com/your-username/blender.git
  3. Set up the development environment following the instructions in the README.md file
  4. Make your changes and submit a pull request

Note: Blender is a complex software suite, not a code library, so there are no code examples provided. The project is primarily written in C and C++, with Python used for scripting and add-ons.

Godot Engine – Multi-platform 2D and 3D game engine

Pros of Godot

  • Lighter weight and faster to learn for game development
  • More focused on 2D game creation, with excellent 2D tools
  • Completely free and open-source, with no strings attached

Cons of Godot

  • Smaller community and ecosystem compared to Blender
  • Less powerful for 3D modeling and animation
  • More limited in non-game applications

Code Comparison

Godot (GDScript):

extends Sprite

func _ready():
    position = Vector2(100, 100)
    scale = Vector2(2, 2)

Blender (Python):

import bpy

bpy.ops.mesh.primitive_cube_add(size=2, location=(0, 0, 0))
bpy.ops.transform.resize(value=(2, 1, 1))

Both Blender and Godot are open-source projects with different focuses. Blender is a comprehensive 3D creation suite, while Godot is primarily a game engine. Godot offers a more streamlined experience for game developers, especially for 2D games, but lacks the advanced 3D modeling and animation capabilities of Blender. The code examples show the difference in approach: Godot uses its own GDScript for game logic, while Blender uses Python for scripting and automation. Choose based on your specific needs in 3D creation or game development.

Unity C# reference source code.

Pros of UnityCsReference

  • More focused on game development and interactive 3D applications
  • Extensive documentation and large community support
  • Easier learning curve for beginners in 3D development

Cons of UnityCsReference

  • Less versatile for non-game 3D applications
  • Closed-source engine core, limiting full customization
  • Potential licensing costs for commercial projects

Code Comparison

Blender (Python):

import bpy

def create_cube():
    bpy.ops.mesh.primitive_cube_add(size=2, location=(0, 0, 0))

create_cube()

UnityCsReference (C#):

using UnityEngine;

public class CubeCreator : MonoBehaviour
{
    void Start()
    {
        GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
        cube.transform.position = Vector3.zero;
        cube.transform.localScale = Vector3.one * 2;
    }
}

Both repositories offer powerful 3D creation capabilities, but they cater to different audiences. Blender is a comprehensive 3D content creation suite, while UnityCsReference focuses on game development. The code examples demonstrate the different approaches: Blender uses Python for scripting, while Unity employs C# for its scripting API.

OpenSCAD - The Programmers Solid 3D CAD Modeller

Pros of OpenSCAD

  • Text-based parametric modeling, ideal for precise and programmable designs
  • Lightweight and focused on 3D printing and CAD applications
  • Open-source with a strong community for 3D printing enthusiasts

Cons of OpenSCAD

  • Limited graphical interface and real-time visualization compared to Blender
  • Steeper learning curve for those unfamiliar with programming concepts
  • Less versatile for general 3D modeling, animation, and rendering tasks

Code Comparison

OpenSCAD:

module cube_with_hole(size, hole_radius) {
    difference() {
        cube(size, center=true);
        cylinder(h=size+1, r=hole_radius, center=true);
    }
}
cube_with_hole(10, 2);

Blender (Python API):

import bpy
import bmesh

def create_cube_with_hole(size, hole_radius):
    bm = bmesh.new()
    bmesh.ops.create_cube(bm, size=size)
    bmesh.ops.create_circle(bm, cap_ends=True, cap_tris=False, segments=32, radius=hole_radius)
    bmesh.ops.difference(bm, objects=[bm.verts, bm.edges, bm.faces], modifier=bm.faces)
    mesh = bpy.data.meshes.new("Cube_with_Hole")
    bm.to_mesh(mesh)
    bm.free()
    return mesh

cube_mesh = create_cube_with_hole(10, 2)

This is the official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.

Pros of FreeCAD

  • Specialized for parametric 3D CAD modeling and engineering design
  • Open-source and highly extensible through Python scripting
  • Better suited for precise technical drawings and mechanical parts

Cons of FreeCAD

  • Smaller user base and community compared to Blender
  • Less developed user interface and steeper learning curve
  • Limited animation and rendering capabilities

Code Comparison

FreeCAD (Python):

import FreeCAD as App
import Part

box = Part.makeBox(10, 10, 10)
doc = App.newDocument()
Part.show(box)

Blender (Python):

import bpy

bpy.ops.mesh.primitive_cube_add(size=2)
cube = bpy.context.active_object
cube.location = (0, 0, 0)

Both projects use Python for scripting, but FreeCAD focuses on parametric modeling and engineering applications, while Blender offers a more versatile toolset for 3D modeling, animation, and rendering. FreeCAD's code emphasizes precise geometric operations, whereas Blender's API is geared towards manipulating 3D objects in a scene-based environment.

JavaScript 3D Library.

Pros of Three.js

  • Lightweight and focused on 3D rendering for web browsers
  • Easier to learn and integrate into web projects
  • Extensive documentation and large community support

Cons of Three.js

  • Limited to web-based 3D graphics and animations
  • Less powerful for complex 3D modeling and animation tasks
  • Lacks built-in physics engine and advanced rendering features

Code Comparison

Three.js (JavaScript):

const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

Blender (Python):

import bpy

bpy.ops.mesh.primitive_cube_add(size=2, enter_editmode=False, location=(0, 0, 0))
bpy.ops.object.shade_smooth()
bpy.context.object.data.use_auto_smooth = True
bpy.context.object.data.auto_smooth_angle = 0.523599

Three.js is ideal for web-based 3D graphics and animations, offering a more accessible entry point for developers. Blender, on the other hand, is a comprehensive 3D creation suite with powerful modeling, animation, and rendering capabilities, making it better suited for complex 3D projects and professional-grade content creation.
