Putting in the shield enemy in the level to test it out

Here is an enemy I've been prototyping, it can shield itself if the player comes too close

In #GLSL there is no isfinite(), so when you're doing an unsafe division, you need to check both isinf() *and* isnan(). Why? Because x/0.0 is inf, unless x=0.0 in which case it's NaN... And this makes me sad.

The trick r==r doesn't work because it is true for inf: it only works as an alternative for isnan() :(

Edit: I guess I could do

bool isfinite(float x) {
return (floatBitsToUint(x) & 0x7f800000u) != 0x7f800000u;
}

Built out the interior ruins of the bridge ruins, for the player to explore and platform inside

Ominous clouds
(Why do I hear latin chants when I open this shader?)

Just learned that my little visual cosine gradient generator tool (from 2015) is featured in this popular video tutorial (1.1M+ views) about artistic shader programming:

The tool is still here:

If you want to use these gradients outside shaders (e.g. for dataviz purposes), the actual gradient functionality is also included in these two libraries:

https://thi.ng/color (TypeScript/JavaScript)

Clojure/ClojureScript version:

I started to build some ruins across the stream for the player to explore some more

New blog post: "Perfecting anti-aliasing on signed distance functions"

My SDF-2D 3D-viewer is finally functional, so to celebrate I'm morphing my pacman/pie into a circle back and forth.

The shadertoy version is visible here: https://www.shadertoy.com/view/333XDH

(For the transform, since it's not present in this version of the code, it's basically a mix according to time between the pie and the sdf+gradient of a circle)

Built a little bridge for the player to cross the stream while adding some collectables for the player to discover

I think I'm done with it. I fixed the clipping and the colors.

I'm still not satisfied with the raymarch glitching a bit, especially on the summit edges. If someone has ideas to improve it, I shared it on shadertoy: https://www.shadertoy.com/view/333XDH

I believe that's because we're matching the exit edge of the shape when it's close, but I'm not exactly sure how to fix that. In any case, patch welcome :)

cool #shader stuff in #godot, using a canvas group to mix colors additively under a subviewport then using a shader to retexture them. The yellow is where lava and acid mix and will have a unique effect and texture #gamedev #gamejam

The box cut is not perfect but we're getting there!

Edit: also, fun stuff, I realized I could return transparent pixels, so the web page background takes over and it looks like the shape is floating on it. It's stupid but I love it :3

You might be familiar with SDF in 2D, but how about a 3D representation of it?

Trying out the river building system and it turned out pretty good in the end, I learned a lot
