آموزش مقدمه ای بر زبان VEX قسمت دوم

This course focuses on the use of VEX applied in two of the most common VFX tasks, Particles, and Volumes.
Although it is an introduction course, it teaches the implementation of very useful and powerful scripting, through the use of attribute VOPs and Wrangles.

It is designed in such a way that the viewer will learn gradually and in a very practical way, the use of many common VEX functions that can be used in many real situations.

In the first chapter, we will explain how to control two fundamental concepts in any kind of simulation; velocity and forces, with simple VEX snippets. We will also explain how to control basic aspects of the particles’ appearance like size, color, and opacity. In the second chapter, we will learn to populate volumes with density from scratch and then “sculpt” the volume’s density to create relative complex shapes like clouds and vortices without the need for simulations.

This course has been designed for beginner level 3D artists seeking to specialize in VFX or artists with a background in other 3D applications wanting to get introduced to Houdini for VFX. It was designed in a way that even completely new Houdini users can easily pick up the main VEX concepts and start creating their own effects in a very short amount of time.
After viewing this course, people can expect to be able to confidently start writing VEX expressions and snippets of code to control the creation and modification of particle systems and volumes.
