Ever wanted to build your own fluid simulation engine, just like the pros use? This course is your first step into making that happen. We’re diving headfirst into the math that powers Houdini, RealFlow, and other simulation powerhouses, starting with the absolute basics of calculus and linear algebra.
🎯 What you’ll learn
- Understand the fundamental calculus and linear algebra behind fluid solvers.
- Learn to compute derivatives and integrals with practical examples.
- Grasp essential derivative operators: Gradient, Divergence, Curl, and Laplacian.
- Prepare for building a solver using pseudocode and Houdini microsolvers.
- Gain insight into the mathematical language used by simulation professionals.
✅ Requirements
- Skills: Basic comfort with elementary school math, some experience with Houdini or other 3D/VFX tools is helpful.
- Tools: Houdini (implied for practical application later)
- Hardware: Standard computer for running Houdini and learning materials.
📝 Description
This course is your gateway to understanding the nitty-gritty math behind fluid simulations. Forget dry lectures; we’re making calculus and linear algebra accessible, even if your math memory is a bit fuzzy. We start from square one, explaining everything from what a function is to the vector calculus that makes smoke, fire, and water sims come alive. By the end of Part 1, you’ll speak the mathematical language of simulation pros and be totally prepped for Part 2, where we’ll actually start building a solver.
Remember, creating a full-blown solver like Houdini takes a massive team and years of work. This course isn’t about replicating that; it’s about giving you the knowledge to get into the field. Whether you want to code your own tools, get a deeper grasp of how solvers tick, or just level up as an FX TD, this is your starting point.
🧑🎓 Who this course is for
- FX artists and TDs who want to demystify the math behind their tools.
- Technical artists curious about developing their own solvers.
- Anyone aiming to become a simulation programmer.
- Learners who want to move beyond presets and understand the “black box.”
