1 DV20447 Virtual-Reality Procedural Experiences with 3ds Max s Max Creation Graph and Stingray Louis Marcoux Senior Technical Specialist Autodesk Canada area.autodesk.com/louis Join the conversation #AU2016

2 Class summary Approach creation challenges procedurally Create and iterate around a roller coasters ride Create virtual reality (VR) experiences Use 3ds Max s MCG for models and animations Use Stingray game engine to build the VR experience. Study some tricks to enhance the experience

3 Key learning objectives At the end of this class, you will be able to: Create procedural content with 3ds Max's MCG Author real-time VR in Stingray Enhance VR experiences by triggering events for the viewer Setup fast updates and alternatives for rides review Decorate real-time environments using animated assets

9 Procedural Content

10 What is Procedural Content? Meaningful Systems Objects with a Parameterized Definition Combination of : Mesh Creation Cloning Transformations Relationships Conditions Functions Mathematics Simple Tools With Large Scale Influence

11 The Max Creation Graph Node-Based editor to build Graphs Graphs that build Procedural Tools Not Wiring Parameters Packages Inputs Nodes Parameters Outputs Primitives Modifiers Controllers MCG Nodes & Compounds Multitude of Functions

12 Tech Demo : Intro to Working in MCG

13 central beam size distance heart line section joints sections length train wagons follow track traction gravity ribs size amount Heart Line Up Line Ground rails size distance up direction pillars size amount base on ground Sections length not it the way!

14 Starting a Project: Best Practices Start small Grow in complexity Clearly identify components to build Avoid rebuilding the same things twice Think generic rather than specific Build Reusable Nodes Use Compounds ad nauseam Layout Intelligibly Group, color and comment

15 Start Small : Creating A Mesh 1 2 vertices face face vertices 3 4 vertices indices Smoothing Groups Mat ID S UV Map 1: (0,5,0) 2: (5,5,0) 3: (0,0,0) 4: (5,0,0) 1: (3,2,1) 2: (3,4,2) : (0,1,0) 2: (1,1,0) 3: (0,0,0) 4: (1,0,0)

21 Transformations In Object Space 0,0,0 is at mouse click location Mesh Creation Happens at 0,0,0 Pivot of ALL Transformations at 0,0,0 No parenting Only Mesh Combining No Arbitrary Pivot Point Plan from Origin to Final Transformation Order is key: 1. Scale 2. Rotation 3. Translation

22 Useful Mathematics Scaling Rule of 3 Rotation ? Degrees and Radians Vector Algebra Translation Trigonometry

24 Working With Splines Clone Along Loft Along Translate Spline Data to Useable Transforms From Origin to Position/Rotation/Scale

25 Working With Splines Data From One Spline Position at percent Position forward No Up! Second Spline Up Direction Right Vector Important to Match Splines Clone Reference

26 Working With Splines Clone At Multiple Percent Values Create and Transform Layout at origin Scale Rotate Translate Loft Along Spline Create Vertices Along Spline Create faces from vertices
