So is it possible to bake the result of the above ^ for static objects like tables and such?
I was thinking in a scene, it could be possible to take the result of the pcss shadowmap and only render it once to a texture or something and project it the same way its being projected with the shadow camera.
I wanted to know whether it was in the realm of possibilities.
Yes it’s possible by using an offscreen scene/canvas.
You render() your floor, a single time with an orthographic camera, then use the canvas as a texture.
You can even use more complex shenanigan since it’s a whole scene captured by a camera.
Like hiding the objects projecting the shadows (require various tricks and your case may need them), adding colors/textures, drawing fake shadows by directly using ctx.drawImage(), re-project your texture/shadows again using spotlights maps.
I posted some code for this (very primitive) method here:
Then run main renderer.
directionalLght_2 must be add and to main scene. scene.add(directionalLght_2);
directionalLght intensity must be 0.5 and directionalLght_2 intensity must be 0.5
directionalLght shadow must be with autoupdating
i posted the source. though i admit it’s a quite complex set up. but still a lot easier than trying to make the three example work imo. i struggled a whole week trying to pull it apart, and i still don’t understand all the potpack stuff, not to mention that the three thing doesn’t actually bake.
you’ll see yourself in that spot over and over again. use react and three because why not. all it does is allow you to make sharable interfaces, like accumulative shadows, hence there is a real eco system, far larger than anything in plain three. three alone can not have that because classes are inapt for sharing, reason why the shadowmap example is more like a whole application you need to untangle and re-purpose whereas outside of OOP you just write <AccumulativeShadows> and it’s done. but if that’s not an option, there’s only the drei source and the progressivemap source, nothing else exists to my knowledge.
