lots more time spent wrangling my python export script and i finally have it so it can export a nice spritesheet with some accompanying json

and now i've got world positions from height going including proper depth sorting :Dgetting the world positions is super easy too, just `input.WorldPos + unitHeight * worldHeight + cameraPos`

its easier to see the world positions if i separate them out by component, so here's X (right), Y (forward), and Z (up) in orderi'm obviously only using the fractional part of the position here for display purposes

behold... cube!figured cubes were a good idea to really visualize the world positions

notice how the character clips through the cubes properly. keep in mind: there's no 3D geometry in this scene, it's all sprite quads!

i'm really happy with how this is turning out. in the past i made this engine but it was about 2000% more complicated and incredibly cumbersome to work with. figuring out that i could simply use the height values of the geometry as both depth *and* to calculate world positions from has simplified things enormouslykeep in mind there's only 4 quads, 8 triangles in this gif too

okay i really wanted to do *some* lighting with this before i went to bed so i quickly crowbarred in a hacky directional light. nice!

whew okay i now have world height encoded into a floating point texture and a way to visualize it (basically goes red > green > blue for every single unit of height)

anyway i think this is looking pretty neat. didn't think it'd work out this welli should be resolving this at a lower res with some blur to hide the artifacts and once i do that it'll be pretty good

okay i've tinkered with it some more and if i don't clamp the values like i was it actually looks way better, although it does push the scene into HDR which i'll have to deal with but that might actually be worth italso realized i can increase the screen step size to get better GI and longer shadows(image cropped cause the edges have artifacts now)

oh *snap*! i figured it out! i was using a weight to blend between the last frame and current frame for global illumination and the problem was that if the weight was too low the effect of the GI was too subtle, but too high and it got unstable. this was the secret to fixing it:float weight = 0.375 * float(nHits) / NumRays;so the amount it uses the GI for the current frame depends on how many rays actually hit anything, so it basically accumulates more strongly for samples where more rays hit, i.e. we're more confident it's the correct result :Dgif shows the new method first (brighter) and then the old method, which looks more subtle *and* has way more shimmer to itahahaha! i am unstoppable! :ameowbongo:

aha! i have figured out how to use GI in LDR without completely blowing out the bright colors from adding GI + direct lightingin the shader where i combine em i calculate the luma of the direct lighting using `dot(direct, float3(0.299, 0.587, 0.114))` and then scale the contribution of the GI by `pow(1 - directLuma, 2)`here's a screenshot with just direct on the left and direct+GI on the right with photoshop color picker to show how slight the difference is on the ground

and now i've stabilized the noise from the GI. and i wanna show the same scene with 0 ambient light first with, then without GIit's really dramatic the difference. without global illumination the black parts not lit by the directional light are just a black inky void, but once you toggle GI on you can suddenly make out the geometry in the shadows

there, fixed that, fixed some of the unwanted blooming there was going on, and added some noise to the GI layer to prevent bandinglooking really good now, i think! here's a gif toggling between GI and no GIand just as a reminder, this is all sprites :3#GameDev #IndieDev #GlobalIllumination

aha! i was having issues with color banding now that im converting from linear to sRGB when showing the screenand it's because turning 8-bit values into other scaled 8-bit values skips over a bunch of colors. i changed all my buffers to 10-bit RGB and now the banding is gonei added a bit of noise to the GI too to prevent any further color banding and now things look nice and smoove even in very dim scenes#GameDev #IndieDev

@eniko That started out as me thinking: "yes the floor is made out of floor."But then I realised the absolute magnitude and the absolute batshit insanity at display here... The character clips through the cubes properly, and they are all sprites.:blobcat_glitch:

@eniko "fatal flaw" or "accidental feature"?
