Gen-3 Alpha can generate detailed and complex simulations, fluids, textures and shapes. Including 2D and 3D text. To learn how, read the prompt guide here: https://lnkd.in/epW-P4S9

Gen-3 Alpha is a great leap forward, don’t get me wrong. What designer wouldnt want a tool like this in their back pockets? But it severely lacks the experimental freedom users need to get useable outputs. By the time you configure your prompts to reach anywhere near your desired results you have exhausted all your credits for the remainder of the subscription. It’s just simply too expensive and impractical for solo-users without deep expense accounts. The results you see are from uncapped prompt testing and refining from their internal team. You won’t find any specific prompt examples from them to even closely recreate this scene. My suggestion (for now) is save a lot more time and money communicating with and hiring a real 3D designer to do the work at this point (shocking right?). Yes they have a resource page on prompt design. But the guides to help achieve better, accurate results is way too generic (everyone who has prompt experience will see this right away) and just adds more anxiety around wasting remaining credits. I’ve yet to see real users share successful prompts and end results. I’ll renew my subscription when I feel experimentation doesnt burn my wallet and my patience. 🤷🏽♂️

By using a 3D triangulated mesh, Pathfinder accurately represents geometric details and curves, ensuring precise and realistic movement modeling. This flexibility allows for easy importing of geometry from CAD geometry or PyroSim models. Building simulations that model real world scenarios is simple and straightforward.

One of the most recent rabbit holes I went down was about geometry processing, specifically remeshing algorithms. I spent quite some time on it, but I am happy with what I learned and achieved ↓ The goal was to find a way to automatically improve clothing mesh quality, control its resolution while preserving input UVs. After spending a few days playing around, I finally landed on the following pipeline: 1. Patterns extraction from UV 2. Seam simplification 3. Points initialization 4. Voronoi construction 5. Constrained Lloyd’s Relaxation 6. Implicit Delaunay Triangulation 7. Refinement 8. 3D Reconstruction Below is a little preview of what I’ve got so far!

People have been asking about joints, weak zones, faults etc in my modelling scheme... so here is a simple, quick, example Part I. Create an oval void midpoint of frictional-cohesive cover 200x120 m, resolution approx. 0.70 of a metre. Normally this void would be stable, but I have introduced a weak surface/joint/fault running from top-left to bottom-right of the section, straight through the void/cavity/tunnel, a bit difficult to show but you should see an inclined notch on left wall at end of model run. I will show 2 quick movies of this 2D discrete element simulation, first is simple geometry as it evolves to a new static state, and the second is the total max. shear strain (damage) accrued doing that... enjoy! If it goes too quickly just change the playback speed...

Using non-linear deformers in MAYA e.g. SINE 1. Create an object e.g. a cylinder 2. Go to Channel box and add divisions to your cylinder 3. Make sure your menu is in modeling mode 4. Go to Deform 5. Hover over to nonlinear 6. Click the top bar to separate it 7. Select the cylinder 8. Go to the nonlinear floating bar 9. Hover over to the sine and click it to add sine to the object 10. Press "T" to bring out the controls, this will bring out the 4 dots 11. Click and drag one of the dots e.g. the middle one, look at the channel box and see which value changes, e.g. the middle handle changes the values of Amplitude 12. Try clicking and dragging the other handles #autodesk #maya #3dmodeling

3D STRUCTURAL FRAMEWORK The Structural Framework method allows you to model faults and horizons in 3D for complex structures.This model handles tetrahedrons, so the model must be converted to orthogonal cells, optimal for modeling Properties, Calculating Volumes and being used for simulation Numerica.

This quick demo shows the Orthogonal Projection node in action, which is one of the basic ways to create 3D grid shapes from 2D ones in Grids. Check out other ways to combine shapes here: https://lnkd.in/dtRvmqpC

Back to element... For efficiency reason, the 3D spring contact can also be modelled with 3D Beam elements combined with beam contact elements
