RenderSystem provides ECS Render Mechanism

func Init

func Init(scn string) (RenderSystem, error)

Gather() - Package customized initialization routine function. Gather is an initialization like function moniker used package by package to initialize a main package construct for API usage. Here Gather returns the main package type which is the RenderSystem and initializes with a GLTF scene file name located in the "dslfluid.com/resources/" directory

func (*RenderSystem) Add

func (r *RenderSystem) Add(e ecs.BasicEntity, mesh defs.MeshComponent, i int) []*defs.MeshEntity

Add() - Adds MeshEntity to RenderSystem

func (*RenderSystem) CompileLink

func (r *RenderSystem) CompileLink() error

func (*RenderSystem) GetParticleBufferId

func (r *RenderSystem) GetParticleBufferId() uint32

Get opengl buffer location id

func (*RenderSystem) Init

func (r *RenderSystem) Init(width int, height int, name string, particle_system bool) error

func (*RenderSystem) Meshes

func (r *RenderSystem) Meshes() error

Meshes() error - Processes current MeshEntity list and configures mesh VAO pointer state for OpenGL usage. Also performs Mesh Preprocessing if neccessary

func (*RenderSystem) RegisterMesh

func (r *RenderSystem) RegisterMesh(meshIndex int, primitiveIndex int, scn *scene.Scene) (*defs.MeshComponent, error)

RegisterMesh - Parses GLTF scene file and fills MeshComponent entity with appropriate GPU intialization parameters in memory

func (*RenderSystem) RegisterParticleSystem

func (r *RenderSystem) RegisterParticleSystem(positions []float32, layout_location int) (uint32, error)

Registers unique particle system (positions only)

func (*RenderSystem) Remove

func (r *RenderSystem) Remove(basic ecs.BasicEntity)

func (*RenderSystem) Run

func (r *RenderSystem) Run(message chan string) error

Run() RenderSystem Runtime

func (*RenderSystem) Update

func (r *RenderSystem) Update(elapsed float64)

Update() - Scene time step update with frame render rendering components associated

func (*RenderSystem) UpdateParticleSystem

func (r *RenderSystem) UpdateParticleSystem(positions []float32)
