WebGL 2 Prototype
We call WebGL 2 prototype the implementation of an experimental WebGL implementation against OpenGL ES 3.0. This prototype have not been submitted to Khronos Group, but to introduce the idea of a full officially specified WebGL 2.0 API. For now, using WebGL 2 Prototype is not secure and will be only available only on Nightlies. The developer playing with our WebGL 2.0 prototype is using it at his own risk of crashes (Gecko crashes, driver crashes and even OS crashes). Mozilla Corporation and/or Mozilla Foundation can change, add, remove features at anytime.
Playground
[coming very soon!]
Development
Development - Design decision
- All WebGL functions must be implemented in WebGLContext
- WebGL function member definitions of WebGLContext should be group by feature as OpenGL ES 3.0 quick reference card do into differents .cpp files
- [ON TRACK] Move functions definition from WebGLContextGL.cpp to distinct cpp files grouped as same as quick reference card do
- [ON TRACK] Restruct all .h lik WebGL1Context.h do
Development - Preliminary
- [DONE] Add WebGL1Context inheriting from WebGLContext
- [DONE] Add WebGL2Context C++ class inheriting WebGLContext
- Enable with about:config flag (webgl.enable-ensecure-webgl2)
- Add virtual func WebGLContext::IsWebGL2
- Add WebGL2 IDL inheriting WebGL 1 IDL
- Edit HTMLCanvasElement::GetContextHelper to allow experimental-webgl2
- gl.getParameter(gl.VERSION) return "WebGL 2"
- [CARRY OVER] Edit GLContext to allow getting a GL3 context; let WebGL 2 use it
- On mac, all OpenGL contexts are shared to each others, therefor they all have to be the same version.
- This is getting fixed in bug 895597.
- Current GFX shader not compatible with OpenGL 3.2 core profile
- Would need to convert shader with ANGLE to the GLSL version we use.
- On mac, all OpenGL contexts are shared to each others, therefor they all have to be the same version.
- [DONE] Bypass ANGLE shader compilation
- Bypass only when the shader code contains #version experimental-webgl2
- Add automatic provide GL_EXT_gpu_shader4
- Add in/out qualifiers in vertex shaders
- Add in qualifiers in fragment shaders
Development - High Priority Features
- [DONE] Add existing WebGL 1 extensions as WebGL 2 features
- WEBGL_draw_buffers
- OES_vertex-array_object
- [DEFERRED] ECT2 texture (need OpenGL 4.3 on mac)
- [DEFERRED] EAC textures (need OpenGL 4.3 on mac)
- [ON TRACK] sRGB textures (GL_EXT_texture_sRGB)
- [ON TRACK] Multisample renderbuffers (GL_EXT_framebuffer_multisample)
- [DEFERRED] Primitive restart with fixed index (need OpenGL 3.2 on mac)
- [DONE] Min/max blend equations (GL_EXT_blend_minmax)
- [DONE] Query objects
- GL_ARB_occlusion_query
- GL_EXT_occlusion_query_boolean
- [ON TRACK] Transform feedback (GL_EXT_transform_feedback)
- [DONE] Instanced Rendering (GL_ARB_draw_instanced)
- [WISHLIST] gl.vertexAttribDivisor (GL_ARB_instanced_array)
- [WISHLIST] gl.drawRangeElements (GL_EXT_draw_range_elements)
Development - Low Priority Features
- [DEFERRED] Uniform buffer objects (need OpenGL 3.2 on mac)
- [DEFERRED] Sampler objects (need OpenGL 4.3 on mac)
- [ON TRACK] 3D textures
- [ON TRACK] Shadow comparisons
- [ON TRACK] Non-square and transposable uniform matrices
- [ON TRACK] R and RG textures (GL_ARB_texture_rg)
- [DEFERRED] Texture swizzles (need OpenGL 4.3 on mac)
- [ON TRACK] Unrestricted NPOT textures (GL_ARB_texture_non_power_of_two)
- [ON TRACK] Mipmap level/LOD tricks
- [ON TRACK] New renderbuffer/texture formats
- [ON TRACK] Half-float vertex attributes (GL_ARB_half_float_vertex)
- [ON TRACK] Stretch blits
- [ON TRACK] Framebuffer invalidation hints
- [ON TRACK] Attach any mipmap level to a framebuffer
- [ON TRACK] Additional pixel store data
- [ON TRACK] Buffer to buffer copies
- [ON TRACK] Texture storage
