  • stream load

https://github.com/KhronosGroup/glTF/issues/1238:

1)Streaming an entire scene by progressively adding mesh geometries
2)Streaming a single mesh geometry by progressively refining bufferViews

(can combine together!!!???)

@ProFive for an HLOD approach to streaming, check out 3D Tiles which is a spatial data structure containing nodes with glTF.

For progressive streaming, there is interest (but no extension AFAIK) in using POP buffers: https://x3dom.org/pop/

• game loop(remove?)

• clone

share material/geometry

• 扩展
  插入用户的逻辑到主循环中的各个阶段(job)中

example:
script component
custom job
custom material
custom glsl

more...

• 多次变换(抽象出模式名！)

example:
transform->compute localToWorld matrix(multiply parent matrix)
model * view * project matrix transform
skeleton animation->compute position(multiply parent matrix)

• compile

example:
compile custom shader language to glsl
