Gumroad – Anas Alaa – Advanced Houdini DOP Simulation Techniques

This is an advanced course dives into the world of DOPs (Dynamic Operators). If you are either a VFX artist, supervisor or a technical developer, you surely work with DOPs and Gas Microsolvers. This world seems so mysterious and difficult to understand. This course will help you dive deeply into the world of DOPs and Gas Microsolvers and solve the mysterious puzzle of this complicated world.

• First Section: Introduction and smoke solver anatomy (2 hrs and 15 mins)
• We will talk about some basic maths needed in the course, volumes and volume types in Houdini and the simple anatomy of the smoke solver, this means the basic gas microsolvers that are used to build a simple smoke solver that handles a simple smoke simulation.
• Second Section: Masking and Detailing Simulations (11 hrs)
• The richest chapter in this course. We will talk about noise in Houdini in details, then we will talk about vector operators like curl, gradient, divergence, laplacian and curvature. Then we will talk about detailing and masking smoke and Pyro simulations in Houdini.
• Firstly, we will talk about the preset already made Gas Microsolvers that are used to add details to the smoke simulations like the Gas Turbulence, Gas Shredding, Gas Vortex Confinement and Gas Disturb. We will not only talk about the settings of these nodes and how they are used, but we are also going to learn how to build them from scratch using Gas Microsolvers which gives you a core knowledge about the world of DOPs and Gas Microsolvers. You will learn how to create these systems from scratch. I am pretty sure that if you learn how to make these nodes from scratch using Gas Microsolvers, you will be able to understand DOP networks and Gas Microsolvers deeply and will be able to build your own systems and advanced techniques in DOP simulations. So we will create them from scratch and go through the math behind them, so we will use so many Microsolvers like the gas match field, gas analysis, gas linear combination, gas field VOP and more.
• Then after talking about the usual ready made ways to detail smoke sims, we are going to create our own custom way of detailing smoke simulations and we will learn how to create custom masks using different things in Houdini and we will put all of that into an OTL to be used in any simulation
• Third Section: Custom Forces and Velocity Fields (8 hrs)
• We are going to create custom velocity fields and forces to control simulations.
• First we are going to create a custom velocity field to get an ocean vortex effect with great banding effect. Then, we are going to create custom curve forces that drive smoke or particle simulations according to a curve. Then, we are going to learn how to create custom forces that work with complex geometry to get an interesting result. Then, we are going to create an interesting particles to word effect to learn how to deal with to object force situation. Then, we are going to learn how to create forces related to an axis. We are also going to learn different ways to apply velocity volumes in simulations like POP Advect by volume and also our ways to blend the velocity in the simulation or applying them as wind, directional drag or full drag. This chapter entails using of a lot of advanced things like point clouds and Volume VOPs to manipulate volumes.
• Fourth Section: SOP Geometry Data and SOP Solver (3 hrs)
• We are going to deal with geometry data and sop solver in DOPs, so we are going to create a snow simulating system and learn how to simulate sand and snow using gas sand forces, SOP solver and impact data
• Then we are going to learn how to create an interesting lava melting effect using SOP solver.
• Then we are going to learn how to mask and detail water simulations using SOP solvers
• Fifth Section (Bonus):Whitewater and Basics of Rendering and Look-development of Ocean Simulations.
• In this section, we are going to simulate whitewater for our vortex, then we are going to talk about the basics of ocean tools and rendering using Karma.
• This course will give you very deep knowledge in the world of DOP networks… after it, you will have very solid base in DOPs, you will have so much better understanding of the workflow in DOPs. You will be able to create your own systems of custom simulations in DOP networks.
