      Hi, I'm new in this forum. It is honorable to see such communities exist. I would like to share my new game. I did for android with unity. I know the game is a little awkward , but you have to know that this game is from the time when Unity's name is Unity3D  I have made my first game when I was 12. Now I am 22.  I have taken a lot of experience in this process and I can make better games nowadays. I have published this game nowadays but actually this game is very old but also it is very special for me :))
      I have just wanted to retouch and share this game, because it has a very important place for me.
       
      DESCRIPTION FROM GOOGLE PLAY STORE

      It's a special free 3D horror adventure action game for the halloween. Fun with scary sound effects and musics, 3D realistic graphics, you will feel the horror in the deep of your heart. Use your reflex. Totally free adventure. Totally scary horror game. 

      Tamarra, she is a beast from our world. She needs to consume souls from innocent people to stay alive. Story begins, the old Elaris tribe had lost their everything because of this beast who lived in the well. Araknas was the most powerful warrior of the tribe.

      Hello! So, I've been the leader of BJP for a while now. I'm a bit bored of taking the role I always take, leader. I was hoping someone out there is looking to forge a team maybe and needs a programmer. 
      I have experience mainly in the Unity engine(C# intermediate) and I have a very small amount of knowledge on Shaders, as well as experience on developing games(usually end up stuck in dev hell) and leading experience from my last team which at one point reached 11 people. I personally love the Unity engine and prefer to use it as it's the development environment I'm comfortable with. 
      I have used Unity for over a year and a few months, I'd consider myself an intermediate at the Engine, but to this day Unity still surprises me. 
      I live in the United Kingdom, I find it a bit strange to work with other programmers as the ones I've worked with tend to leave their code heavily unoptimised and I'm a on the go optimise kind of guy, I also like to get things done quickly.
       
      If you're a new team and need a programmer that has high levels of ambition and strives to maintain the motivation throughout the team, then I'm your guy. I don't care if you're just beginning because I'm all for helping people learn!
       
      To finish this off: I like to get things done and I like to get them done right the first time, if I fail I will do it again and again, etc, until I loose all motivation. So if you're a modeller or an artist, please don't leave me to do all the modelling/art as well as the programming and sound. I do have experience in all those areas but my main power is in programming and I'd prefer to keep it that way.

      Hey guys!

      I'm new here and I recently started developing my own rendering engine. It's open source, based on OpenGL/DirectX and C++.
      The full source code is hosted on github:
      https://github.com/fleissna/flyEngine

      I would appreciate if people with experience in game development / engine desgin could take a look at my source code. I'm looking for honest, constructive criticism on how to improve the engine.
      I'm currently writing my master's thesis in computer science and in the recent year I've gone through all the basics about graphics programming, learned DirectX and OpenGL, read some articles on Nvidia GPU Gems, read books and integrated some of this stuff step by step into the engine.

      I know about the basics, but I feel like there is some missing link that I didn't get yet to merge all those little pieces together.

      Features I have so far:
      - Dynamic shader generation based on material properties
      - Dynamic sorting of meshes to be renderd based on shader and material
      - Rendering large amounts of static meshes
      - Hierarchical culling (detail + view frustum)
      - Limited support for dynamic (i.e. moving) meshes
      - Normal, Parallax and Relief Mapping implementations
      - Wind animations based on vertex displacement
      - A very basic integration of the Bullet physics engine
      - Procedural Grass generation
      - Some post processing effects (Depth of Field, Light Volumes, Screen Space Reflections, God Rays)
      - Caching mechanisms for textures, shaders, materials and meshes

      Features I would like to have:
      - Global illumination methods
      - Scalable physics
      - Occlusion culling
      - A nice procedural terrain generator
      - Scripting
      - Level Editing
      - Sound system
      - Optimization techniques

      Books I have so far:
      - Real-Time Rendering Third Edition
      - 3D Game Programming with DirectX 11
      - Vulkan Cookbook (not started yet)

      I hope you guys can take a look at my source code and if you're really motivated, feel free to contribute :-)
      There are some videos on youtube that demonstrate some of the features:
      Procedural grass on the GPU
      Procedural Terrain Engine
      Quadtree detail and view frustum culling

      The long term goal is to turn this into a commercial game engine. I'm aware that this is a very ambitious goal, but I'm sure it's possible if you work hard for it.

      Bye,

      Phil

      I have attached my project in a .zip file if you wish to run it for yourself.
      I am making a simple 2d top-down game and I am trying to run my code to see if my window creation is working and to see if my timer is also working with it. Every time I run it though I get errors. And when I fix those errors, more come, then the same errors keep appearing. I end up just going round in circles.  Is there anyone who could help with this?

      Hey
      I'm dealing with ribbons following the shape of multiple spline segments. It's straightforward to compute the direction at any point along the spline. However the ribbon also got a flat shape and I'm struggling with finding a way to compute the angle of the ribbon in the plane perpendicular to the direction.
      To illustrate what I mean here's a piece of code that almost worked:
      float3x3 rotMtxFromSpline; rotMtxFromSpline[1] = normalize(splineDir); rotMtxFromSpline[0] = normalize(cross(float3(1, 0, 0), rotMtxFromSpline[1])); rotMtxFromSpline[2] = cross(rotMtxFromSpline[0], rotMtxFromSpline[1]); // Rotate rotMtxFromSpline[0] in the rotMtxFromSpline[0]-rotMtxFromSpline[2]-plane to align with float3(0, 0, 1) dir rotMtxFromSpline[0] = normalize(dot(rotMtxFromSpline[0], float3(0, 0, 1)) * rotMtxFromSpline[0] + dot(rotMtxFromSpline[2], float3(0, 0, 1)) * rotMtxFromSpline[2]); rotMtxFromSpline[2] = cross(rotMtxFromSpline[0], rotMtxFromSpline[1]); The problem with this code is when the spline segment becomes perpendicular to (0,0,1)-dir as the orientation switch from one side to the other very easily.
      The approach above is kind of a global approach and I'm thinking if there's a way to append some info to each spline segment to remedy the issue.
      Anyhow I wanted to post this question in case anyone had a similar problem that they solved or maybe anyone know some web resource dealing with this issue?
       
      Thanks!

3D Constant/Uniform Buffer's Shader State and Optimal Uniform Buffer management

Recommended Posts

Posted (edited)

Hey guys! Three questions about uniform buffers:

1) Is there a benefit to Vulkan and DirectX's Shader State for the Constant/Uniform Buffer? In these APIs, and NOT in OpenGL, you must set which shader is going to take each buffer. Why is this? For allowing more slots?

2) I'm building an wrapper over these graphics APIs, and was wondering how to handle passing parameters. In addition, I used my own json format to describe material formats and shader formats. In this, I can describe which shaders get what uniform buffers. I was thinking of moving to support ShaderLab (Unity's shader format) instead, as this would allow people to jump over easily enough and ease up the learning curve. But ShaderLab does not support multiple Uniform Buffers at all, as I can tell, let alone what parameters go where. 

So to fix this, I was just going to send all Uniform Buffers to all shaders. Is this that big of a problem?

3) Do you have any references on how to organize material uniform buffers? I may be optimizing too early, but I've seen people say what a toll this can take.
