Brush-Painting splats in VR, inclusive undo+redo if you screw up.

Probably one of the most important features ever: Undo & Redo. Now also working with transformations of selected splats. Although it's currently a slightly "lossy" undo because I'm only saving the transformation matrix and result of inverse may not exactly match original.

The splat editor harbors a dark secret.

Apparently this is a perfectly fine projection matrix for software rasterization? - No near or far - Could be reduced to a vec3 and "ndc" is then just a dot product? - Linear depth since ndc.w is -viewPos.z. Not quite normalized but does not matter for software raster.

Garden-table-removal tool now also working.

Productive-procrastination: My attempt at dynamically growable arrays, but using virtual memory. - No copies as array grows. - Initializing array with 400GB virtual memory, and physically comitting as much memory as needed. github.com/m-schuetz/varr…

Florian Hahlbohm had the idea that the editor could be used to colorize old statues, e.g., giving it a nice copper color, or if you've got an old greek one, paint the garments to what they originally might have looked like. Also, his perspective-correct splats are nice in VR. :)

Spring in Vienna is so awesome.

We'll present our work on Splatshop next tuesday at the HPG! Looking forward to visiting Copenhagen. Paper: diglib.eg.org/bitstream/hand… Code: github.com/m-schuetz/Spla…

It's worth mentioning that this app uses the new 3DGS SOGS compression in PlayCanvas. The entire app (code + data) is 8.3MB. 🗜️
