for compatibility with mobile GLES drivers.

santouits 3c1cd2873b WebGL1 some changes 
glRenderBufferStorage doesn't accept the _DEPTH_COMPONENT24_OES so I changed it to GL_DEPTH_COMPONENT16
https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/renderbufferStorage
https://www.khronos.org/registry/webgl/extensions/rejected/OES_depth24/

Enabled ext_shader_texture_lod extension. I guess it does the same like the GL_ARB_shader_texture_lod extension, but in WebGL1
https://www.khronos.org/registry/webgl/extensions/EXT_shader_texture_lod/

And last WebGL1 doesn't allow indexes not constant, so I changed it into a loop reading this:
https://stackoverflow.com/questions/19529690/index-expression-must-be-constant-webgl-glsl-error
 2019-01-22 13:40:28 +02:00
santouits e7e9a7cc6c webgl1 doesn't like backslashes in #define 
According to
https://www.khronos.org/registry/OpenGL/specs/es/2.0/GLSL_ES_Specification_1.00.pdf
, backslashes aren't necessary supported as line continuation characters
in preprocessor directives

Rémi Verschelde 57416bfbce GLES2: Define 'lowp' for OpenGL 2.1 
Precision qualifiers are only used on OpenGL ES 2.0 and 3.0,
and while OpenGL 3.3 defines them for compatibility (but without
practical effect), they're missing from OpenGL 2.1, so we define
them to prevent compilation errors.

Fixes #24521.

Rémi Verschelde 4226d56ca9 Style: Enable clang-format on GLSL shaders 
As of clang-format 6.0.1, putting the `/* clang-format off */` hint
around our "invalid" `[vertex]` and `[shader]` statements isn't enough
to prevent a bogus indent of the next comments and first valid statement,
so we need to enclose that first valid statement in the unformatted chunk.

Marcin Zawiejski bd5ff205b2 Revert "Batch GLES2 draw calls" 
This reverts commit f55039b194.

The GLES2 batching seems to require more testing and tweaking in order
to actually make the performance better on Android devices. It's been
proved with #21184 that the current implementation has it's drawbacks
therefore I suggest reverting the commit for now.

Thomas Herzog 73fe08be2e GLES2 refactors 
This commit unhacks some parts of the 3D rendering.

Most notably:

 - possibility to use negative texture units
   (no longer weird manual index allocation for user samplers)

 - refactoring of light code, now sorts in a different way,
   should yield better performance

 - fixes a crash while saving (because of "Illegal instruction" execution)
   when using a decent compiler (clang, it's clang. Thanks GCC for not telling me about UB).

Hugo Locurcio 31c12f05c4
Tweak the default SpatialMaterial properties 
Roughness is now set to 1 by default and albedo is now white,
even on meshes that do not have any materials defined.

This means there is no longer a visual difference between a
mesh with no materials defined and a mesh with a default
SpatialMaterial defined.

but integrating into other platforms is planned.
