Render Graphs

Overview

In this tutorial we will cover render graphs, what they are and how they can be used in your shows to create complex visual effects.

We will also discover how to link sensor data to parameters in the render graph to create interactive environments.

We’ll start by using a Leap Motion : a low-cost, easy-to-use and powerful hand sensor, perfect for prototyping effects.

At the end of the tutorial, we’ll cover how to easily migrate the project to a Hokuyo LIdar sensor.

We’ll begin a project from scratch and start building with basic shapes before progressively adding to our composition to create more complex render graphs and visual effects.

*Resolution :
In this tutorial series we will be working with a Full HD (1920×1080) display as an external monitor.
If you are working with a different resolution don’t forget to adapt all the values to your resolution accordingly.
Drivers :
To use the Leap Motion with Kinetic we recommend you use this driver

Introduction

Part 1 : Presenting the Render Graph

In this first part we’ll begin a project from scratch with a basic setup and present what a render graph is, and how they differ from compute graphs.

Part 2 : Calibrating the Leap Motion

In this video we cover how to calibrate the Leap Motion sensor in a compute graph.

Part 3 : Linking the sensor to the Render Graph

In this part we cover how to link the sensor data from the Leap Motion to an instance of a render graph.

Part 4 : Enhancing the visual effect

In this video we learn how to combine nodes together to create an enhanced visual effect based on user interaction.

Part 5 : Using interactive shapes as masks on media

In this video we learn how to use a render graph as a mask to create shapes that reveal media on the timeline based on user interaction.

Part 6 : Migrating the project to a 2D Lidar

In this last part, we migrate the project to another setup with a Hokuyo LIdar and a video projector.

*Info :
In this part we have adjusted our project to the resolution of our video projector which is 1920 × 1200 and no longer 1920 × 1080.
Don’t forget to adapt the values to your own setup.

Modulo Kinetic version : 5.0.1
If you are using a more recent version of Modulo Kinetic there may be some differences between the video and your interface.
If you are using a less recent version of Modulo Kinetic some features may not be available.
