• Demanding learning curve for non-technical users

Code Examples for TouchDesigner & Blender

TouchDesigner: Creating Real-time Audio Spectrum

This friendly yet complex example visualizes audio input in real-time in TouchDesigner. Preliminary knowledge in Sound CHOP (Channel Operator) and Python integration in TouchDesigner is needed.

# TouchDesigner Python Code for Real-time Audio Spectrum
import TouchDesigner as td
# Create a sound CHOP
sound = td.OP('/project1').create(td.SoundCHOP, 'audio')
# Configure to use input
sound.par['source'] = 'chan1'
# Create a python script
script = td.OP('/project1').create(td.ScriptCHOP, 'pyScript')
script.par['cooktype'] = 'always'
# Attach script to sound
script.inputConnectors.append(sound.outputs[0])
# Update script
script.par['script'] = "inputs[0]"

Blender: Animated Windmill Generation

The following intermediate-level example generates a generic windmill and animates it in Blender. At least basic understanding of Python and object creation in Blender is mandatory to comprehend the logic.

# Blender Python Code for Animated Windmill Generation
import bpy
import math

# Set windmill parameters
height = 10
sail_width = 2
sail_height = 10

# Create main shaft
bpy.ops.mesh.primitive_cylinder_add(location=(0, 0, height / 2), radius=0.2, depth=height)

# Create sails
for i in range(4):
    bpy.ops.mesh.primitive_cube_add(location=(math.sin(math.pi / 2 * i) * sail_width / 2, 
                                              math.cos(math.pi / 2 * i) * sail_width / 2, 
                                              height), 
                                    scale=(sail_width, sail_width, sail_height))

# Animate windmill
for frame in range(100):
    bpy.context.scene.frame_set(frame)
    bpy.context.active_object.rotation_euler[2] = frame * math.pi / 50
    bpy.context.active_object.keyframe_insert(data_path="rotation_euler", index=2)

TouchDesigner or Blender: Your Final Stop

After unraveling the potential of both powerful tools, let’s decipher the ultimate choice based on your specific needs.

Media Artists & Performance Creators

Our verdict leans towards TouchDesigner. With its procedural OpenGL compositing, custom control panels, multi-display support, it’s a perfect pick for creating immersive experiences, interactive installations, and live shows. Operator categories offer robust control over various aspects of your creations.

3D Modelling & Animation Enthusiasts

Consider Blender, known for its well-rounded functionalities including UV mapping, texturing, rigging and skinning, fluid, and particle simulation. The versatility makes it highly suitable for creating sophisticated 3D models and animations.

Open-Source Advocates and Community Learners

Blender triumphs with its open-source ethos, community-led development, and generous availability in a multitude of languages. It’s a haven for enthusiasts who thrive in communal knowledge-building environments.

In essence, TouchDesigner is preferable for interactive multimedia content creation favoring operators-based control, while Blender’s strength lies in comprehensive 3D capabilities and a thriving open-source community. Choose as per your specific endeavor.
