As I explore materialX with Houdini Solaris, I wanted to create a procedural scratch shader. The standard noise nodes are quite limited and couldn't achieve the desired effect I was looking for. However, materialX's math nodes offered the flexibility to build the necessary patterns. Drawing inspiration from various online resources, I developed this initial shader. While it needs more optimization, the results were promising for a quick first pass. There are 5 layers of scratches at various scales, rotations and thickness. I'm not aware if there is a method to run a loop with materialX as that would make layering things much easier. For now its just manual work to create multiple layers.

Using Houdini, I created a water simulation where a whale jumps out of the ocean, resulting in dynamic splashes. This involved animating the whale and utilizing FLIP fluids for realistic water interactions. Whitewater and spray particles were added to enhance the visual impact of the splash.

This is R&D of a dynamic river simulation in Houdini using the FLIP solver, which ensures realistic fluid flow. In addition, I created a set with the props covered in snow, which enhances the overall environmental reality. Kindly give me your feedback’s on this. https://lnkd.in/g9p-p_9W SideFX Software #Flipsimulation

Vulkan porting (fron OpenGL 4.X) started at Aug 14th, 5 months approx. since then, way less than I expected 🎉 I have ported all the base rendering of my engine: models, textures, materials, shaders generation system (from Data to GLSL). Next step: PBR Shading model ☀️

Dip your toes into GLSL by coding a simple monochrome effect shader with the GLSL TOP in TouchDesigner by following this tutorial from The Interactive & Immersive HQ: https://iihq.tv/48MStN7 GLSL is the OpenGL shading language and runs directly on the GPU - this allows you to handle multiple tasks at once and has big performance advantages compared to CPU executed code. #interactiveimmersivehq #touchdesigner #glsl

⚡ | Ray Tracing with Rust 🦀 | Context: I'm starting a new open source side project where I'm going to challenge myself to implement the Ray Tracing technique for lighting 3D environments in real time using only Rust from absolute 0. 📖 | Project This is certainly a very challenging project and that's why I'm 2x more excited about it, I'm using the book "The Ray Tracer Challenge" as a basis, which explains the principle of TDD. 🌞 | Ray Tracing This is a modern and advanced light tracing technique, which accurately simulates the behavior of light rays in the scene, taking the entire lighting system and reflections of the environment to another level. The downside is that this is a very heavy algorithm. This is why it is not yet widely disseminated. However, it is already used in 3D Software and in the most recent Games, being practically a mandatory part in AAA (large) games, such as Cyberpunk 2077 by CD PROJEKT RED, a reference when it comes to Ray Tracing, as illustrated in the image below. 🌱 | journey This was a general overview and I intend to continue bringing the evolution of this project and take the opportunity to share the knowledge I have been acquiring along the way :) ✅ | Github: [https://lnkd.in/dmH32EEj] 🧙♂️ | "A life without challenges is not worth living" - Socrates

SideFX Software has previewed the new features and improvements coming to Houdini 20.5, a sizeable update set to hit the shelves in mid-July. Introducing updates across the entire toolkit, a novel Copernicus tool, and more: https://lnkd.in/dhJQ3SdW #sidefx #sidefxhoudini #houdini #houdinifx #3d #3dart #procedural #proceduralart #procgen #3dsoftware

Here's my first render with Karma XPU. Overall, it's not as fast as a fully GPU-based renderer like Redshift, and I faced these issues: 1. It gets really slow with transmission materials. 2. It seems that caustics don't work. 3. Sometimes the GPU doesn't work at all, and I had to close and reopen Houdini. 4. Overall, it's much harder to clean the noise. About the simulation: I wanted a big wave crashing into the cliff, and I tried to combine ocean waves with ocean spectrum and gave it to dop as a velocity field. Around 24 million particles for the flip sim and 42 million for the whitewater. #Houdini #FX #FLIP #karmarenderer #simulation #karma

Made the classic game Snake using OpenGL,irrKlang,Freetype and written using C,C++ 😄 . Some features are : phong lighting, collision detection, edge detection, respawning. I have written a short blog on some of the challenges i faced while writing this, you can find it at : https://lnkd.in/dx_VgKxZ This is my first 3D project that feels like an actual project. Learned a lot while writing this. There are still some things that could be added but bringing it to a close for now. Code : https://lnkd.in/deKMiRNU
