Open root directory in Visual Studio 2019\n\t1. Select Build \u003e Build All\n\t1. Run le3d-demo (or custom executable target)\n* Others (CMake GUI):\n\t1. Run CMake\n\t1. Select root directory as source\n\t1. Select an output directory (`out/...` is ignored)\n\t1. Click Configure and pick your build environment; ensure no errors are thrown\n\t1. Click Generate\n\t1. Open project and build\n\t1. Run le3d-demo (or custom executable target)\n* Shell:\n\t1. `cmake -G \u003cgenerator\u003e . -B out/\u003cbuild_dir\u003e -DCMAKE_BUILD_TYPE=\u003cbuild_config\u003e`\n\t1. `cmake --build out/\u003cbuild_dir\u003e`\n\n### Rendering\nLittleEngine3D uses an OpenGL 3.3 Core context by default, with `GL_ARB_texture_filter_anisotropic` loaded, and uses forward rendering with a fixed number of point and directional lights. Each `Mesh` contains one `Material` which supports diffuse and specular textures and various built-in uniforms as defined in `env::g_config` (entire struct can be overridden).\n\n### MVP Target\n- [x] Perspective and orthographic projections\n- [x] 2D view and quad drawing\n- [x] Model loading\n- [x] Text rendering\n- [x] Debug primitives (cube, sphere, cone, etc)\n- [x] Threaded Renderer\n- [x] Async manifest loader\n- [ ] Particle systems (using instancing)\n- [ ] Shadows (directional lights)\n- [ ] ImgUI integration\n- [ ] Trivial collision system\n\n### Submodules / External:\n\nPublic (use via `#include \u003clibName/.../header\u003e`):\n\n- [glm](https://github.com/g-truc/glm)\n\nPrivate:\n\n- [glfw](https://github.com/glfw/glfw)\n- [glad](https://github.com/Dav1dde/glad)\n- [stb-image](https://github.com/nothings/stb)\n- [tinyobjloader](https://github.com/syoyo/tinyobjloader)\n- [physfs](https://icculus.org/physfs/)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkarnkaul%2Flittleengine3d","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkarnkaul%2Flittleengine3d","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkarnkaul%2Flittleengine3d/lists"}
