Code Examples for TouchDesigner & Houdini

TouchDesigner: Pulse-generator

This fun Python snippet generates a repeating visual pulse in TouchDesigner. Ideal for beginners, it leverages the Timer CHOP and demonstrates the use of boolean logic for visual effects.

import math
def onPulse(channel):
    if channel.index == 0:
        period = math.fabs(op('wave1')['chan1'])
        return period
    elif channel.index == 1:
        amplitude = math.fabs(op('wave1')['chan2'])
        return amplitude
    return

Houdini: Random Color Assignment

This intermediate-level Houdini code example assigns random colors to different faces of a mesh. It makes use of VEX coding in the wrangle node and accentuates your understanding of working with randomness and geometry characteristics.

int prims[] = primpoints(0,@primnum);
foreach(int pt; prims){
    int seed = pt+ch('seed');
    vector color = rand(seed)*ch('mult')+ch('add');
    setpointattrib(0,'Cd',pt,color,'set');
}

As a prerequisite for the TouchDesigner code, you should have the Timer CHOP set up, possessing familiarity with Python and the OP Interface. For the Houdini code, a basic understanding of VEX scripting in the context of 3D modeling is required. Always ensure to adapt the ‘seed’, ‘mult’ and ‘add’ channel parameters to your randomness preferences and color ranges.

Please note, these example snippets are illustrative and may require modification to work in a specific project’s context. Always review and understand code before implementing it in your project. Use the provided frame as a guide for code presentation.
