Plan of action

• Setting up project for cross-platform build support
• Import mesh/textures
• Rendering in a scene
• Keyboard & Mouse inputs
• Window resize
• Importing c# written fluid-simulation in this engine
• Migrating 2D spatial hashing
• Shader pipeline
• Support for mac
• Find a way to debug coding after built application
• Add Proper logging & profiler system
• Create Basic UI elements like a button and text
• Documentation & UML Diagrams
• Auto UML Creator tool
• Implement ECS
• Add physics library (jolt / physx / box2d / bullet3) -> physx
• Add FPS Counter
• Implementing PhysX (left handed or right handed)
• Multithreading for rendering and update loop
• Creating library for performing maths functions
• Reworking camera system and merging rotations with other objects in game using new custom math library
• Implement Tracy throughout engine especially for tracking memory allocations
• Creating vehicle using PhysX
• Break...
• Updating bash files for supporting physx on mac and web builds
• Creating wrapper for switching between different physics engine
• If simple, add basic light and sky box
• Position, Scale, Rotation handles after selecting objects
• Improving current shader pipeline to handle shaders dynamically
• Create Unique ID generator for items
• Documenting done items and different approaches and used libraries
• Researching on auto-build deployment and build status
• On repo update - auto build emscripten for web and upload
• Creating support for multi-scene compilation
• File Manager (Reading from file paths and avoiding enums)
• Ability to read/write on file for saving import references (instead of hard-coded enums)
• Create build modes for debug and release
• Find a way to isolate and build code while developing simulations
• HTML navigation multi scenes on demand (async download and load scenes)
• Support for window
• Create a template for dump-testing shaders
• Add Unit Testing
• Dynamic Window Layout & save'n'load
• Simple tool for importing files like textures/meshes
• Setting up Vulkan
• Creating 3D spatial hashing (showcase & in-built)

Build

Folder Structure

Compatibility

• Unix Console on Mac
• Mac (x84) (Rosetta)
• Windows
• Web

Tools

• Emscripten
• OpenGL ES3
  • Mac: OpenGLES/ES2/gl.h
  • Emscripten: GLES2/gl2.h
• SDL/SDL2 (mac framework) or GLFW
• Imgui
• Tracy Profiler

Setup

• Run project/console/setup.sh to install packages
• Run project/console/build.sh to build the project (auto runs the executable)
• Run project/emscripten/build.sh to build the project for web
• Run project/macos/setup.sh and run Physicat.xcodeproj and hit play button

Issue Links to Query

If emcc on terminal won't work?

Activate PATH and other environment variables in the current terminal $source ./emsdk_env.sh

Shortcuts to note

• https://stackoverflow.com/questions/6780895/visual-studio-parameter-listing-intellisense

Mini - TODO

• Explore what's happening in internal_ptr script with the templates and internal_ptr thing
• Empty namespaces name declaration & using namespaces vs include headers
