Also the support is very good. And if you are in a third world country like me (Argentina) they have localized prices in my local currency so it's really affordable.

Backend engineer here, (not game dev) but the process is similar. You learn the basics of programming syntax. You design a few projects from the ground up, learn tons and patterns. You work with other people, learn more patterns. After several real world projects, things become quite easier to implement. Also you don't have to be a super programmer to start, you'll never know everything. You just have to know enough to get started, and then experience will make you a better dev.

Maybe have a look at dual quaternions as a replacement for 4x4 transform matrices. Mathematically speaking, they are the algebra of quaternions in tensor product with dual numbers, and they represent any rigid transformation as a corkscrew motion. You only need 8 floats to store a dual quat, so that's quite the improvement. However you will need to convert them back to matrices in the shaders which may hit the performances a bit. I never used them personally in game dev, as I was more interested in the maths side of things, but I know some big game engines use them. Good job on your website man!
@pigworts22 жыл бұрын
What's the advantage over just a quaternion plus a translation and scale, that would also be eight floats. It also allows any rigid transformation (reflections can be achieved with a negative scale), and it seems like it would be cheaper to convert into a matrix.
@AntonioNoack2 жыл бұрын
But they can't represent non-uniform scale themselves. So it would be 8+3 = 11 floats instead of 12 for this 3x4 matrix.

@DFPercush2 жыл бұрын
My intuition says that it would be better to use a per-instance attribute buffer as it would allow better memory optimization than a global storage buffer where the gpu has to wrangle many random (as far as it knows) memory accesses across multiple lanes.
@sc5shout2 жыл бұрын
@@DFPercush I'm not sure what you mean by saying random. If you create a UBO/SSBO (whatever) with size for 1024 instances, the GPU will only loop through linear, well-defined memory region. It's like you'd do something like this in C++ std::vector transforms[1024]; for(int instanceID = 0; instanceID
@DFPercush2 жыл бұрын
@@sc5shout Yeah I understand. Hmm, I guess as long as it's a read only buffer in that stage, it would probably be ok. But you might want to check vkPhysicalDeviceLimits :: maxUniformBufferRange (64k on my RTX 2060) as well as maxVertexInputAttributes (32 on same card). Beyond those size limits, you're talking about storage buffers, which are writable from shaders, and that's when you can run into cache coherency issues slowing you down. Although there might be a way to flag it as read only. ... But I haven't tested any of this, so, short answer no. :P

What happens when you spawn new cubes? You create new entity in c++ memory, update the main vertex buffer + update instance buffer? Also, when these cubes are moving is the instance buffer also being updated every frame by some physics engine event? PS. Oh, as i'm writing this, i realized that you probably don't update main vertex buffer - geometry is already there, since it's the same cube.

Just keep in mind that changing shaders is usually quite a bit slower than a whole bunch of draw calls, so it isn't the only thing to keep in mind when doing instanced rendering, especially when you start pushing like 100k instances or more.

@@theRPGmaster The actual context switching is what costs in terms of swapping from shader to another, setup time for the shader is a thing too but generally that is a fraction of the time the context switch takes. So what you want is master shaders that can do everything but are fast as hell, but those are contradictory goals obviously.

Why do the cubes in your game fall at a constant speed, gravity is an acceleration that should be added to the cubes velocity so the bigger the mass of the cube and the further it falls then the faster the velocity until it matches the air resistance at which point its velocity would be constant, or am I barking up the wrong tree, it just looks kind of weird watching the cubes slowly fall

Hey, I've been toying with the idea of using instancing in complex scenes in unity. Basically just taking GameObject scenes we already have and converting all the rendering to using an instanced rendering system to avoid having to do batching (which don't quite work well with baked lights). I was also considering doing culling on a compute, do you know of any obvious pitfalls with this approach? Started watching your videos recently, they're really good.

I am a very very stupid idiot and I'd like to know two things. 1. What actually _is_ a draw call? Why is it expensive? Why is it expensive for the CPU and not (presumably) the GPU? What does it arrange to happen on the GPU? 2. It seems obvious that you can't just give a triangle's mesh data as an instance and use that triangle for literally everything in every scene forever, but why?
@DFPercush2 жыл бұрын
A draw call basically starts a "thread" on the gpu. The reason they are considered slow is that it takes time for the hardware to set up everything before it starts running your shaders. It's like booting up a computer, kind of. It's not really that bad, but if you're doing it thousands of times per second it starts to add up. There's also a "ramp down" time. Some pixels might finish running their shader before others, and the gpu has to finish everything before it can switch to a different pipeline and start rendering something else. So you're not getting full utilization at that point. 2. Actually, in theory it might be possible to render a scene by using several instances of a single triangle, depending on the material, and just transforming that. But that would take a lot more data to store all those transform and be generally less efficient than having an indexed mesh. Plus you'd have to generate that asset data somehow for all those transforms, and that's just not the way 3d editing software works. But fundamentally that's what a mesh is.
