hexgame/TODO.md

##TODO:

• renderer
  • check over renderer, camera, gooey init after changes
  • pass in frame time to camera movement functions to decouple speed from framerate
  • test camera speed when moving with composite vector
    • may be fixed?? need to test by examining camera position between frames and compare the distance
  • add 3d orientation widget to gooey
• make hashmap grid type
• position entities on grid hexes
• remove checks for colors, textures from render_group functions
  • actually cannot remove checks for texture because some meshes aren't loaded properly
  • maybe can cause loading mesh to fail when more than one mesh per file
• figure out bug in fragment shader when removing commented line
• move input handling out to new file, controller?
• map generation
• pathfinding
• assimp animation
• replace aixlog with custom logging iostream?
• think about combining mesh data and render_group data to save some memory
  • actually don't need to save the vertex/normal buffers after passing to opengl
• use a storage pool for assimp meshes allowing reuse across entities
  • also cache textures from loaded meshes for re-use
• replace remaining calls to malloc/free with safe(r) function in util.h

##LATER TODO:

• add initial opengl constant for INT_MAX, and checks in render_group functions
• try out YAML instead of JSON (make sure can still use schema validation)
• move from COLLADA output to glTF (GL Transmission Format) https://www.khronos.org/gltf/
• add config.js/yaml for application config (remove some defines everywhere)
• maybe try deferred rendering at some point to use a ton of lights
• add cpu perforcmace counters in render loop
• check for memory leaks w/ valgrind

##DONE:

• add palette texture colors to hexgrid
  • map palette index to UV coords for shader in hexgrid render_group
  • fill hexgrid uv buffer with coordinates
  • set use_texture to true on hexgrid render_group render_objects
  • update hgUpdateColorBuffer to change uv buffer instead of color buffer rename function and replace calls
  • remove current_color/stored_color from hex_info struct
    • remove uses of these in hexgame.cpp and hexgrid.cpp
  • re-arrange vertex attributes in shader and render_group to remove color_buffer
• update hgUpdateColorBuffer() to use POD instead of gl_buffer
• remove color buffer from render_group
• implement texturing to reduce the number of meshes generated by assimp from materials (currently creates a sepereate mesh per material)
  • need to do UV mapping on models, and parse UV data in shader
