+# Things to do:
+
+- [x] Drawing triangles
+- [x] Drawing cubes and lines for testing
+- [x] Y up coordinate system, left handed
+- [x] Drawing a cube with perspective
+- [x] Culling triangles facing away from camera
+- [x] Texture mapping
+- [x] Basic linear transformations - rotation, translation, scaling
+- [x] Bilinear filtering of textures / subpixel precison
+- [x] Nearest filtering
+- [x] Fix the gaps between triangles (it also improved look of triangle edges)
+- [ ] Perspective matrix vs simple perspective
+- [x] Perspective correct interpolation
+- [x] Depth buffer
+- [x] Gamma correct blending - converting to almost linear space
+- [x] Alpha blending??
+- [x] Premultiplied alpha???
+- [x] Merge with base
+- [ ] Lightning
+  - [x] GLOBAL Ilumination
+- [x] LookAt Camera
+- [ ] FPS Camera
+- [x] Reading OBJ models
+- [ ] Reading OBJ .mtl files
+- [ ] Reading complex obj models (sponza)
+- [ ] Reading PMX files
+- [ ] Rendering multiple objects, queue renderer
+- [x] Clipping
+  - [x] Triagnle rectangle bound clipping
+  - [x] A way of culling Z out triangles
+    - [x] Simple test z clipping
+    - [x] Maybe should clip a triangle on znear zfar plane?
+    - [x] Maybe should clip out triangles that are fully z out before draw_triangle
+- [ ] Subpixel precision of triangle edges
+- [x] Simple profiling tooling
+- [ ] Statistics based on profiler data, distribution information
+- [x] Find cool profilers - ExtraSleepy, Vtune
+- [ ] Optimizations
+  - [ ] Inline edge function
+  - [ ] Edge function to integer
+  - [ ] Use integer bit operations to figure out if plus. (edge1|edge2|edge3)>=0
+- [ ] SIMD
+- [ ] Multithreading
+- [ ]
+- [ ] Text rendering
+- [ ] Basic UI
+- [ ] Gamma correct and alpha blending
