First milestone complete, animation system & 3rd person ctrlr from scratch. Even got Xbox ctrl input cause im no keyboard warrior 😘
Sensible thing is to do jumping next, nay! Tis time for COMBAT !!! 👊🗡️

Refactored 1D Blendspace proto to work in my new from scratch anim sys. Root motion built in & works with fixed frames. Next add xbox ctrler to move mewtwo around infinite world. Can't wait to do combat next :)

I created an orbit camera controller with the support for #SpaceMouse as an input device. This lovely device is recognized by the gamepad api in the browser, so yey. Very niche feature but fun to have around :)

Enjoyed learning how @PavelBoytchev's planar rotations work, lovely way verts are weighted. Heres my 2nd stab at reproducing a single joint of it. Redid most of the #maths so its very simple w/ lots of comments. Free code, enjoy!

Made a skeleton renderer that uses instanced meshes & custom shaders for the bones. Idea is to easily restyle your skeleton previews all you'd like without all the hard animation mathy bits getting in your way
Tis Free! Enjoy.

Someone shared a link to @dedouze_'s new animation tool today at work & felt inspired enough to try to build a very basic concept prototype using #threejs. Tis was a fun exercise this evening.
Code is free, enjoy !

Dealing with cameras lately so tonight I put together 4 examples of moving a camera to fill the screen with the desired object. Free code, enjoy.

Here's a basic proto of creating a wind system. A way to visualize wind dir plus run compute to get wind dir at a certain spot. Gonna use it someday to animate cloths, hair & grass. #opensource, enjoy !

like interesting prototypes? editor stuff? How about this lil example of using gpu picking, viewport rendering, and hermite curves to give your camera a bit of humph while editing & viewing in realtime
#threejs
Heres the result of all that Asinc bs Ive been dealing with for awhile. Lovely to finally see this model animating. Its swaying booty is just a nice bonus. There are some bugs & lil hacks to get it working. I'll do a full refactor after I get boneSprings workin again 😊

Got all that arc #maths fixed up into a non-iterative IK solver. I used the leg bones of the AT-ST since the lens vary oddly & id wanna make sure it'll work. Sadly its really late to try it on the bot but soon!
Solver is #opensource, enjoy
#threejs
DemoSrc: sketchpunklabs.github.io/threejs_prot...
Finally getting arcAngle from arcLen & chordLen working using Inverse Sine Cardinal, took 6 yrs. Now I can improve one of my IK solvers & get a starwars AT-ST doing walk cycles from human animations :)
Code of the #maths are free.

My employer @getcartwheel has allowed me 2 #opensource a feature I made, a mini view that renders in ur scene. U can render anything you want, first use case was a zoomable view. Made possible by using scissor, viewport & stencil buf
#threejs
Anyone interested in hacking on Octahedral Impostors for @threejs.org ?
I took @sketchpunk.bsky.social's octahedron unwrapping code and contributed atlas generation (and some suuper hacky impostor rendering) – maybe someone can push this further for the community :)

I may need to build 3D Gizmos again, so thought I put together a simple ex of all the main actions needed. Got line & plane translation with visualizers for the raw data. FromScratch raycasts + mathlib, free & portable

Reached the first milestone in building a basic #physics engines. Has linear / angular vel, Box Collider, pnt constraint, no dep. Lots of comments, res links, great starter ex for anyone interested in the topic

Code/Demo sketchpunklabs.github.io/threejs_prot...
The toy #physics engine Im trying to put together, I found a tutorial on using BVH+MortonCode to handle the broadphase stage. 2 days of reading & coding I have an ex with lots of comments for anyone interested in this fun datastruct.
#threejs
github.com/codecrafters...
Found this great resource that links to various tutorials & examples of how to build things from scratch. I've already started reading one particular build your own 3D physics engine tut & how to completely build your own react library :)

I recently did a test on the topic of websockets. I made a barebones & vanilla example of a multiplayer client /server game. Also added an NPC pixel & xbox controller input. #free + good learning example /w lots of comments

Put together an ex of gpu picking, an alt for ray casting. Uses renderlists so no need to keep extra scene of objects. For point picking I get intID plus worldspace hit pos. Also made screenspace RECT selection :)
#threejs #opensource

Because of changes to #threejs over the years I need a new repo to continue doing prototyping. Now I can run multiple versions, webgl/webgpu, better organization & updated my visual debugging to work in latest version plus github pages. Clone away :)
oh... this is exactly the sort of retirement I want. Wake up late, think of doing more work into 4 bar linkage, see people like my old octasphere imp on x then get inspired to make a better version & make it usable for anyone. Thats like peek life living for me, work on whatever whenever :)
Demo/Code: codesandbox.io/p/sandbox/pr...
Revisiting @prideout's Octasphere, this time around I added extra params to reshape it into a 3D rect / capsule shape. No dependences. Engine agnostic, so should work in #threejs @babylonjs etc. Sadly no UV coords tho. Fun shape to have around.

The final first prototype of auto skinning a 3D mesh using compute shaders on #webgl & running in #threejs. All the code is up & free for anyone to learn or use.
Big step closer to cloning mixamo 🥳

Code&Demo

Heres how to voxelize a triangle mesh using #WebGL's TransformFeedback compute within #threejs. Its just the first step to making Voxel Geodesic AutoSkinning. Here's hoping to replace mixamo with something #opensource-y😊
#gamedev #indiedev
Code&Demo
codesandbox.io/p/sandbox/th...
#WebGL's TransformFeedback used to run a compute shader that voxelizes an SDF shape. The modified buffer is part of an instancedMesh that renders a cube for active voxels. BONUS, Raymarched volume render of the SDF too.
#threejs #glsl
Prototype of using #WebGL's TransformFeedback compute shaders to perform custom skinning with #threejs rendering the results. Mean u can pose/animate a char once then render multiple shells as static meshes. When I have time, I'll try out fur shells & a walk cycle 😊

Coding burn out... switching to modeling. Redoing what I had left off with MsCosplay. This time around going to really focus on edge flow to make things fit & animate better. Its my personal goal to finish her model this year... i fear doing the face tho.😪
#blender #b3d
Here's the final version of my rotation gizmo. Pretty snazzy. The render bits are dependent on #threejs but the rest is easily portable to other engines if needed.
