Explore an intermediate Houdini course on VEX and matrix techniques to rotate objects in 3D, and begin creating mystic effects inspired by X-Men.
Explore basic 3d rotation in Houdini using VEX quaternions, angle and axis inputs, and the qrotate function, with radians conversion and transform node setup.
Learn to rotate a cube around its center by computing the center with get bounding box, moving to the origin, applying rotation, and transforming back to the original position.
Master pivot rotation in houdini using vex 2023 by rotating around the bottom center pivot instead of the center, using point position, vector pivot, and procedural group workflows.
Explore a SOP solver in Houdini that drives rotation with a mask attribute and attribute transfer. Build a feathered mesh, color-code sides, and remember motion paths with a sub solver.
Apply the for loop to propagate the code to every leaf, compute a center pivot, and rotate parts with quaternions while using the mask attribute to drive the animation.
Explore the Mystique effect by driving random rotation with a detail attribute iteration and a remapped angle. Visualize with a mask attribute to fade the grid and reveal evolving geometry.
Create a line and transfer the mask attribute to geometry, then use a wrangle and solver to animate and transfer positions, fine-tune the attribute transfer, and visualize the motion.
Explore per-piece rotation in Houdini by creating a pivot at the center, applying masks and the center point, and driving angles with iteration-based values while adapting axes per geometry.
Adjust rotation direction in Houdini VEX by swapping cross product inputs and setting the angle to -180; use the feed value, and download Udemy project file for the correct rotation.
Apply cross product to compute a perpendicular rotation axis from the geometry normal and a custom axis 010, normalize, and use quaternions to rotate the piece in Houdini VEX.
Hello everyone! This course will show you all the steps involved in setting up an mystique effect in houdini.
You should have working knowledge of Houdini before enrolling in this course.
I will provide the hip file and there are no extra assets to download (only mixamo animation, you can find free anim online), all you need is just Houdini software.
If you have any questions, please feel free to ask me and I will try my best to answer.
This course will be using Houdini 19, you should have no problems following along with the lecture videos with lower versions.
Breakdown of the course:
Introduction to quaternion and matrix with easy example
Fix problems we find in previous lessons.
Use the same code on a static object.
Try creating the same effect on an animated object.
I will be presenting a very straight forward and approach to creating an FX shot like this. I also demonstrate a lot of small examples when I introduce a new concept.
If you have been using Houdini for a little while, you should have no problems following this course.
We will not cover the rendering part because the course is focusing on creating the mystique effect, but feel free to ask rendring questions.
I hope you enojy the course!
