Delicious Max 8 Tutorial 7: That primitive action

[@sousastep]

this is the main effect that I use for my LED sousaphone bell. Thanks!

Setting the node to float is a revelation. I've done so many feedback patches that dont fade out to a mysterious black but instead leave awkward grey ghosts.

[@netaelad3969]

Sam, thank you so much for these videos!

I still think this month should be called holy Samuary

Your anecdote reminds me of a similar thing in Jedi Academy, where if you did one of the saber dance moves into a corner, you could go through the level geometry and end up in a textureless void below the level that would show the glitchy afterimage of your character.

Maybe all star wars games have this glitch? It's like the Wilhelm scream of glitches.

[@beea4401]

​@@dude837 My best bet is that some game engines don't assume a default render color, and instead write the color value of the nearest pixel for every (x,y) in the viewport. One way to do it would be to project the viewport (linear algebra matrix projection) into the world, and then project (geometric projection) into a kind of square cone (specifically a rectangular prism where one of the composite rectangles is strictly a scalar multiple of the opposite rectangle, and the other 4 rectangles are mirrored by their opposite) called the frustrum, and then grab the closest pixel (lowest positive z value in the viewport coordinate system, assuming z->+inf is the far field axis; or alternatively the smallest/largest (x,y,z) world coordinate within the line segment from the near field pixel to the corresponding far field pixel) for each (x,y) coordinate in the viewport. Then, you can also assume that your entire level is geometry, so for each (x,y) pixel in the viewport, you can put that directly in the render buffer. Which means that every frame you're not looking at level geometry, the old pixel (or second oldest pixel if the engine uses double buffering, effectively making the afterimage half the frame rate of the actual frame rate) gets stuck. I think this would also work the same for engines that use ray tracing, but I know that, for example, Blender has that default grayish erase color which fixes the problem entirely. I don't know how much of that you know since it's clear you know a bit about 3d rendering in general, so sorry if that's redundant.

needs more likes - sam is legend.

Is max a part of Toon Boom Harmony?

[@Bobtheclamm]

hey dude! you're the best, do you still have the cleaned up Autechre patch from 4 years ago?

[@spaceshipable]

That fade thing is to do with the blend mode, I've seen it in Processing a bunch of times. The solution in Processing is to use a SUBTRACT blend mode. Otherwise I think there's some multiplication which gets rounded to the ghost colour

[@maorpaz]

yes!! wonderful job

[@MicheleZaccagnini]

My favorite part is the alphablend. So simple and effective! Thanks. BTW "primitive action"?

[@enkisumer]

Dearest Sam, It was great to see the 3 ways to swiz, that is always helpful, and to see mistakes..e.g. erase_color 0 0 0. Seeing the effect of something missed is very valuable, i for one learn more that way from you, (because you know the solution,(when i do it hours of head pounding follow, which i not as fun.)) In which prior video did you go over "Basic Envelop extraction" I've been trying to learn that, but i didn't have the lingo. (you mention it at 17:45)?

[@Clementmathieuopgraven]

Dear Sam, thanks a lot for your helpfull and your teaching ! I just wondering where you learned all of this ?! BTW In two weeks I see many of your tutorials, I'm absolute big fan of the delicious max ! cheers~ @fromfrance 1.2

[@MatheusLeston]

man, you are getting into Weirdcore territory (which I found recently is also a Max user, btw)

[@dude837]

Weirdcore is an absolute legend, so I take this as a massive compliment!

[@MatheusLeston]

@@dude837 Of course it is. Specially if you are into oh-god-i-will-not-sleep-at-night-or-maybe-have-a-seizure-right-now type visuals.

[@Titanionz]

thx!

[@beea4401]

You should probably edit the s3 link into a public link.

[@dude837]

Ah thank you thank you, I thought I'd done that!

[@jkRatbird]

Fucking gorgeous. Thank you!
