I'm trying to add some details like grass, rocks, trees, etc. to my little procedurally-generated planet. The meshes for the terrain are created from a spherified cube which is split in chunks (chunked LOD).
To do this I've wrote a geometry shader that takes a mesh as input and uses its vertex positions as locations where the patches of grass will be placed (as textured quads).
For an infinite flat world (not spherical) I'd use the terrain mesh as input to the geometry shader, but I've found that this won't work well on a sphere, since the vertex density is not homogeneous across the surface.
So the main question would be: How to create a point cloud for each terrain chunk whose points were equally distributed across the chunk?
Note: I've seen some examples where these points are calculated from intersecting a massive rain of totally random perpendicular rays from above... but I found this solution overkill, to say the least.
Another related question would be: Is there something better/faster than the geometry shader approach, maybe using compute shaders and instancing?
I would like to start off with thanking you all for this community. Without fora like these to assist people the already hard journey to making an own game would be exponentially more difficult. Next I would like to apologize for the long post, in advance...
I am contemplating making a game. There, now that's out of the way, maybe some further details might be handy.
I am not some youngster (no offence) with dreams of breaking into the industry, I am 38, have a full-time job, a wife, kid and dog so I think I am not even considered indie? However I recently found myself with additional time on my hands and decided I would try my hand at making a game.Why? Well mostly because I would like to contribute something, also because I think I have a project worth making (and of course some extra income wouldn't hurt either to be honest). The first thing I realized was, I have absolutely no relevant skill or experience. Hmm; ok, never mind, we can overcome that, right?
I have spent a few months "researching",meaning looking at YouTube channels, reading articles and fora. Needless to say, I am more confused now than when I started. I also bought some courses (Blender, Unity, C#) and set out to make my ideas more concrete.
I quickly discovered, I am definitely not an artist... So I decided, though I do plan to continue learning the art side eventually, I would focus on the design and development phase first. The idea being, if it takes me a year or more solely learning stuff and taking courses without actually working on my game, I would become demoralized and the risk of quitting would increase.
So I thought I would:
1: Keep following the courses Unity and C# while starting on the actual game development as the courses and my knowledge progress.
2: Acquire some artwork to help me get a connection with the game and main character, and have something to helm keep me motivated. (I already did some contacting and realized this will not be cheap...). Also try to have the main character model so I can use it to start testing the initial character and game mechanics. For this I have my first concrete question. I already learned that outsourcing this will easily run up in the high hundreds or thousands of dollars... (lowest offer so far being 220 USD) I am therefore playing with the idea of purchasing https://assetstore.unity.com/packages/3d/animations/medieval-animations-mega-pack-12141 with the intention of then have an artist alter and/or add to the animations (it is for a Roman character so some shield animations are not going to work the same way.). This way I could start with the basic character mechanics. Is this a good idea, waste of money,...? Any suggestions? I then have a related but separate question. Is it a good idea to buy Playmaker (or some other similar software I haven't yet heard of like RPGAIO), and using this for initial build, then changing/adding code as the need arises?
3.Get a playable initial level ready as a rough demo and then starting to look for artist for level design and character/prop creation.
I would really appreciate some input from more experienced people, and especially answers to my questions. Of course any advice is extremely welcome.
