simple3d

This library aims to be a simple tool to let you visualise simple 3D primitives. To provide maximum flexibility the library is using ANGLE (https://github.com/google/angle) as graphics backend. C++ namespace - Simple3D. Currently there is no aim to support multiple windows, and contexts, but it might be provided in the future.

Development.

Code style - Google C++ Style Guide. (https://github.com/cpplint/cpplint)

Components.

1. (graphics) Objects related to 3D rendering.
2. (context) Window manager: creating windows, GLES contexts, main loop, etc.
3. ImGui support (?)
4. Texture manager
5. Tools for optimizing visualisation of massive amounts of data.

Dependencies.

• glad (https://github.com/Dav1dde/glad)
• GLFW (https://www.glfw.org/).
• ANGLE (https://github.com/google/angle)
• OpenGL Mathematics (GLM) (https://github.com/g-truc/glm)
• assimp (https://github.com/assimp/assimp)
• Dear ImGui (https://github.com/ocornut/imgui)
• stb_image (https://github.com/nothings/stb)

Dependencies for building examples:

• vcpkg (https://github.com/microsoft/vcpkg)

Limitations.

• Context can be initialized only once, otherwise you can expect undefined behaviour.
• Only one instance of shader per type. Makes shaders less flexible, but increases overall performance as it decreases switches between shader programs.
• Only one instance of renderer per scene. Couldn't come up with a good way to allow that, but also provide easy library interface.

TODO:

Overall.

• Create CMake config of library
• Organize components in folders.
• Create documentation (doxygen).
• Add support for non-desktop devices: Android, IOS.

1. Objects related to 3D rendering.

• Create basic API/interface of library:
  • Scene object (relative position of objects).
  • Camera object (render capabilites).
  • Misc (additional 3D primitives).
• Implement API/interface:
  • Simple lighting.
  • Scene object (relative position of objects).
  • Camera object (render capabilites).
  • Controls for Camera object.
  • Misc (additional 3D primitives).
• 3D primitives:
  • Cuboid.
  • Triangle.
  • Spehere: basic, icosphere, cubesphere.
  • Particle.

3. Window manager: creating windows, GLES contexts, main loop, etc.

• Initialization, and termination.
• Context management.
• Input management.

4. ImGui support (?)

• Add ImGui support.

5. Model manager

• Create simple model loading.
• Add support for embedded textures (assimp).

6. Tools for optimizing visualisation of massive amounts of data.

• Optimized ParticleRenderer.
