Acerola Jam has ended and I was actually participating the whole time! I made a fully ray traced solitary confinement simulator with a realistic sun cycle driven by real world time. I made everything from the shaders to the materials to the music. The only thing I didn't make is the skyboxes.

[@HA11EYS_COM3T]

You really don’t need music theory to start, absorbing what you can and learning as you go is a good idea :) If what you make sounds good without music theory, it can’t sound worse with music theory (unless you get too caught up in rigid theory) My recommendation would be to pick up composition software or a DAW and just start creating, it’s fun and it’s a good start :D

[@NoodleDoodleWasTaken]

@@HA11EYS_COM3T Thanks for the encouragement! But I've already been doing that for a year or so, and I find it really difficult to do make music without any knowledge. I plainly don't know where to start, what kinda notes should I play and when. So most of my tracks were really frustrating to make, since I just put stuff semi-randomly until it sounds good, which takes a while, and it usually doesn't even sound all that good. I've picked up a class yesterday tho, and it's already helping me a ton!

actually playing as a roomba looks fun

[@KingBobXVI]

In college I had a project where we built little robot cars that drove themselves around avoiding obstacles using three IR distance sensors, not too different to how a Roomba works, minus the front bumper. I'm imagining a game where you have to navigate a 3d space, you don't have a 3d view, your only visual is three dots on the screen, shaded to represent the distance to the nearest point directly in front of you, and two offset by a 30 degree angle on either side. Maybe another visual element could be a top down map of your path showing where you've been already so you can double back or predict where things might be in the room. Now I actually kind of want to make this, lol.

[@theSoundCarddatabase]

Very nice. The music portion I found very captivating, first with the implementation of events happening on minutes and hours, but also for the explanation of chords that's the clearest I've ever heard as a non-musician. Somehow this demo reminds me of the "The Room" prototype by Peter Molyneux back in 2005... the aspect of time was quite important in that game and you could wind or rewind the wall clock to make the hours pass and the days go by, and the light reacted accordingly.

[@rrrfrdd4497]

Another banger as always. I'm currently trying to build my ray tracer from scratch, so this is a huge inspiration.

[@williammanning9323]

"What's the rendering equation? ...I don't know" got me lol For anybody who's wondering, it's the formal mathematical way of saying "for our particular viewing angle of a particular surface point, add up all light which comes into the surface from any direction and happens to bounce towards our viewing angle". That sum of light is written as an integral, because integrals are how you sum an infinite number of infinitely small things. In practice, integrals are usually approximated by summing a *finite* number of chunky things. You may remember from high-school calc, approximating the area under a curve by splitting it into rectangles and summing the rectangles' area together. Similarly, in a ray-tracer we trace a very limited number of incoming light rays, and assume each one covers a fairly broad cone of incoming light directions hitting a broad patch of surface. You get better approximations, a.k.a. more realistic graphics, if you increase the number of rays and decrease the effective size of each one (or decreasing the size of the surface patch, by increasing resolution), so that you're not glossing over so much detail. The integral is defined as the limit as they become infinitely thin, and infinitely numerous, impacting an infinitely small surface. The inside of the integral, describing the amount of light coming in from a particular direction and then bouncing into your eye, depends on a number of factors. Each of them is pretty intuitive once you understand it (for example, one term is the dot product of the incoming direction with the surface normal, because less incoming light is able to hit a surface area if that area is rotated to be thinner from the light's POV).

[@Akosmo]

The overall concept of your game (especially the randomized death date) reminds me of an old art game called The Graveyard by Tale of Tales. In it you play as an old woman visiting a graveyard, sitting down, thinking about things for a while, and then leaving. You can repeat this as many times as you want. In the paid version, she may randomly die during a visit. I seem to remember that if you try to start the game up after the old woman dies she won't be there for future visits, but I can't confirm that.

Since we're on the topic of ray-tracing, have you heard of the game Mirror Drop? It was made when ray-tracing usage in games was just starting to take off and uses ray-tracing to create seemingly infinite repetitions, perfect reflections, and non-Euclidean geometry

[@BobzBlue]

In a voxel game that uses ray tracing would it be theoretically possible to skip mesh building using the chunk data for ray collision similar to a 2d tiled platformer collision system for a performance gain?

[@mettaursp309]

By mesh building do you mean detection of ray intersections with objects already registered & tracked in the scene & available for rendering, or construction/loading of the objects? For the ladder it's better to get it all registered & tracked beforehand. For the former, yeah, those kinds of broad phase checks apply for rays as well. For scenes with triangle meshes it's fairly common to approach with a top level acceleration structure for the full scene, and bottom level acceleration structures for individual objects. An acceleration structure in this context would usually just be something like an AABB tree or a KD tree. You would cast a ray into the top level node of the tree, and gradually working your way down the tree, eliminating nodes that the ray can't traverse through, until you hit the items in the leaf nodes. The top level structure would store objects, with references to which mesh bottom level structure is used, and the bottom level structures would store triangles. This prevents the ray cast function from trying to compare against meshes well outside of the ray's path, and from trying to compare against triangles well outside the ray's path. For a voxel game as an example you could modify the top level structure to use a voxel grid structure to represent either voxels or chunks. If you're going to be using GPU accelerated ray tracing then you're going to be more limited in how you're allowed to modify the acceleration structure though. Last I checked it was a lot more inflexible.

[@BobzBlue]

@@mettaursp309 I've been thinking about such a technique for a while, however given my lack of experience the only thing I got from your reply was that it would be difficult to give the gpu chunk info (sending stuff to and storing things on the gpu cache or memory is intensive in high quantities). I was really just daydreaming about Minecraft's mesh building for rasterized rendering, the ray tracing used in minecraft probably uses that same mesh and I thought of a method I used in scratch for tiled based collision for wolfenstine styled rendering. It might be a job for a cpu anyway as it requires checking the coodrinates of a ray and reference it to the tile data to detect collision. Maybe the 3d tiling could be equivalent to vertexes, however again, I have no clue whether a gpu could accept such data in any way.

[@1e1001]

dunno exactly what you're describing but i know teardown's main rendering thing is raymarched voxels, maybe that's similar to what you're describing

[@Roxor128]

Sure. Wolfenstein 3D does the 2D version for rendering, then once it's found the wall intersection, draws an appropriately scaled column of pixels for the distance from the camera onto the screen, followed by appropriately scaled sprites over the top.
