Hello everyone : Some test using my tool for creating procedural Tree growing and Rigging : Tutorial Trailer : link to Tutorial : https://www.hossamfx.org/treesrigginginhoudini/ thanks Hossam Aldin Alaliwi www.hossamfx.org

https://www.hossamfx.org/treesrigginginhoudini/ Hello Everyone : this tutorial is about creating and animating trees in Houdini FX in Procedural way . you will learn how to create your own tree model and how to animate it in different weather like windy day, normal wind ........etc. also you will see how to simulate a growing process : what i mean in growing is : you can select at which age of tree you want to start growing to final complete model , so you can start growing from zero or you can grow from winter tree to a beautiful spring tree with leaves and young branches . i will show you firstly how to create a tree model in SpeedTree software for about 1 hour and then move to Houdini and create python code to define the hierarchy of branches and build a procedural wire dynamic network with some math concepts of course . Houdini rigging tools and chops techniques in our list also to add more option and realistic to animation . in the link you can find more description about this tutorial . More info Here: https://www.hossamfx.org/treesrigginginhoudini/

Hello Everyone, http://www.hossamfx.org/mathinhoudinivol2/ Hello Everyone, Description: In volume two of Math in Houdini training. We will continue exploring the big role of math in creating visual effects and controlling the simulation behavior and this time we will move to more advanced concepts and provide cool projects. I will explain one of most important physical parameter: the gradient. And show you how to use it in rigging and collision and give you wide idea about using gradient in different operations in Houdini also We will go indepth with matrices and learn cool techniques using the matrix: it is the “Frame of Reference” you must know this magic secret about matrix. If you have many questions about Quaternion parameter, So we will dive into this concept and answer all questions with cool projects and we will see how to create quaternion field to effectparticles motion and if you don’t know what is the Vector 4, we will have cool project about using vector 4 inside the wire solver dynamics. And I will show you how it to build your own cloth simulation from scratch, this part will give wide idea about how the dynamic solvers work and what is the constraint , gravity , and how the collision is calculated ….. and many other math topics. Thank you. Lesson plan WHAT IS THE GRADIENT, AND FOR WHAT !!! all dynamic solvers use Gradient and normal and velocity and collision calculations, all this Physical Parameters use Gradient, you absolutely Know what is the Gradient !!! ? 1. Gradient & Slope Relationship– Are there any relationship between it? 2. It can create Normal – slope can create normal, how? 3. Speed and Velocity calculates –it is awesome how slope can calculates speed for everything. 4. Slope & Dot product in Rigging – No more tutorials about how to Rig the wheel. 5. Gradient of surface – Slope can create Gradient 2D field. MATRIX IN DEPTH !!! we will start by talking about for what we need matrix and next it will be more clear how it is easy to use matrix, and Frame of Reference is strong concept that you must have idea on how to use. 6. Why we created the Matrices – to understand matrices I must know for what it was created. 7. Recreating the Matrix – Now we will see how it is more easy with Matrices. 8. Frame of Reference – it is cool Concept you must know how to use with matrices. QUATERNION, NO MORE QUESTIONS ??? you don't know any thing about quaternion! you will know every thing about it, for what, when to use, how to control and how to build field of quaternion to advect particles. 9. What is the Quaternion – You will Have depth understand of this Scary parameter. 10. Quaternion Field part 1 – Quaternion inside Dynamics can create awesome animation in Particles. 11. Quaternion Field part 2 –How to Keep Particles inside defiened Volume using quaternion attribut VECTOR 4 IS A QUATERNION, ... !!! the orient attribute in the Wire solver is very important and you must know how it work, in this project we will manipulate this Attribute to create procedural dynamic animation. 12. Quaternion & Wire Solver – Big role of Quaternion in wire object. 13. Feelers & Quaternion part 1 –Feelers of insects moving around all the time, we will simulate this motion with quaternion. 14. Feelers & Quaternion part 2 –How to control the physical parameters of feelers to get nice real motion. SIMULATION CODE & COLLISION it is very important to get depth understand of how the Dynamic solvers work, we will see how we can build cloth simulation and add collision to this simulation using the Point VOP and Sop Solver. 15. Apply Gravity –Without any dynamics solvers, we will create our solver and start by adding gravity force to objects using the point vop and sop solver. 16. Create Cloth Force – Define the force spring between cloth object points and create pin constraint for new solver. 17. Gradient & Collision –Gradient of Volume is the way to create collision between objects. ِAll Content With Project Files . Full information Here

http://www.hossamfx.org/mathinhoudini/ Description: This training demonstrates the big role of Math in creating visual effects and controlling the simulation behavior in Houdini FX animation software. I will cover many of the most popular math topics in computer graphics and I will show you how to apply these concepts inside Houdini with some cool projects. I will focus on what we need to know from math for using in VFX without diving into complex mathematical details as this training is not about pure math. I will show you how the Dot product can be used with the Flip Fluid, and how to create windy curves using the Cross product, and how the Matrices can determine the velocity and store the rotation data.....and many other features of using Math in Houdini. Lesson plan 1. Introduction to vectors – What is the vectors and, why we need it in math and physic and CG ?. 2. Dot product definition – Introduction to Dot product equation in math: input, return, formula, spatial situation, deficiency of Dot product . 3. Dot product and angle calculate – Simple example in Houdini for using Dot product to calculate angle between two geometry. 4. Dot product inside flip fluid 01 – Create custom force attribute for controlling fluid behavior. 5. Dot product inside flip fluid 02 – Solving deficiency in Dot product and final behavior test. 6. Cross Product definition – Introduction to Cross product equation: what we need to know about Cross Product for using in CG, and what we don't need ?. 7.

hossam01983 replied to hossam01983's topic in Education
thanks thank you , i focused on math inside Houdini and provided examples for every idea and some times more than one example, starting from easy setting to more advanced use of the mathematical concept. i tried to stay faraway from pure math and the things that we don't need to use in vfx or it is has very small use in very spacial situation. 
Hi every one i finish this system and use it in my new training Procedural Modeling Technics in Houdini FX I used wide variety techniques for creating this system shown the flexibility of Houdini FX This training help the Houdini beginner feel the power of Houdini in additional the new Houdini FX versions, and help them go up to intermediate level. from hossam01983 on https://vimeo.com.

Hello everyone this is my new training, hope you like it, more in formation on www.hossamfx.org . from https://vimeo.com/user44594439 on https://vimeo.com. This training focuses on how to create procedural nerve cells system in Houdini. It covers the using of many Houdini nodes in the SOPs level, like the foreach loop, vop nodes, polygonal nodes, using attribute’s nodes and creating geometry based on attributes. The course covers various procedural modeling technics in the new versions of HoudiniFX using Houdini nodes without use scripting. The last result is system to generate nerve cells from any model like box or sphere or human head. This training aimed to the intermediate Houdini’s users. Hossam Aldin Alaliwi Regards ! 1 reply
