Detailed Description

RenderManager class.

Render manager handles basic rendering states

model / view / projection matrix
- model matrix can be directly set
- or can be set with translate / rotate / scale functions
- view and projection matrix can be directly set
- or can be set using Viewpoint class and RenderManager::camera function
- matrices can be push / pop'ed
- pushing and popping camera will push/pop both iew/proj mat
viewport and framebuffer
- keeps track of current state
- also provides push / pop functionality
shaders
- keeps track of current shader
- get & cache location and set values of uniforms for model, view, projection matrix
drawing mesh
- sending vertex position/color/normal/texcoord to bound shader
- mesh can be regular cpu-side al::Mesh
- or gpu-stored al::VAOMesh

!. writing shader for al::RenderManager

modelview matrix: uniform mat4 l_ModelViewMatrix;
projection matrix: uniform mat4 al_ProjectionMatrix;
vertex position layout (location = 0) in vec3 position;
vertex color: layout (location = 1) in vec4 color;
vertex texcoord: layout (location = 2) in vec2 texcoord;
vertex normal: layout (location = 3) in vec3 normal;
