0.5

• Frustum culling using bounding box for level props (optimize fps).
• Move gizmo/grid, basic camera, terrain, skybox, sphere to opengl-utils or to separate repos.
• Shot sound with fmod (irrklang was causing audio glitches).
• Fix: No intersection with target behind camera ray.

0.4

• Move calls to glm::inverseTranspose() outside game loop.
• Update shaders version to GLSL 4.60.
• Use instancing to draw the same geometry multiple times.
• Factory classes to manage the lifecycles of shaders & textures.
• 3D model for targets to shoot.
• Enable face culling except for doors/windows.
• Parse tilemap & calculate model matrices for each prop in constructor.

0.3

• Put generic code in a git submodule.
• No duplication of vertexes in Sphere & Cylinder geometries.
• Don't stretch textures (bake in uv-coordinates).
• Move camera up/down & jump when hitting spacebar.
• Multisampled anti-aliasing with GLFW.
• Move to OpenGL-3.3 & GLSL-3.3 (attributes in vertex shader).
• Draw gizmo & 2D grid using lines.
• Sum up contributions from multiple lights with attenuation.
• Normal mapping for tiles & 3D models.
• Add see-through windows to level.
• Also tested: rendering to framebuffer texture & splitting viewport.

0.2

• Load 3D model in .obj format with Assimp.
• Construct a terrain using heightmap & texture it with a splatmap.
• FPS-like camera movement.
• Render level from tilemap text with its props.
• Collision between player & level walls.
• Gun attached to bottom of screen & play sound when shooting.
• Destroy cube targets on intersection with cursor & increase score.

0.1

• Render OpenGL scene on GLFW window.
• Draw geometries.
• Rendering of cube with different shaders (color, textured, with specular reflection).
• Camera movement with arrow keys and mouse.
• Render 2D HUDs.
• Write text with Freetype.
