2020-05-14Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocksRémi Verschelde
Which means that reduz' beloved style which we all became used to will now be changed automatically to remove the first empty line. This makes us lean closer to 1TBS (the one true brace style) instead of hybridating it with some Allman-inspired spacing. There's still the case of braces around single-statement blocks that needs to be addressed (but clang-format can't help with that, but clang-tidy may if we agree about it). Part of #33027.

2019-09-06Create shadow_vec for altering shadow computationazagaya
In 2.1 and 3.0, light_vec could be modified for altering shadow_computations. But it broke shadows when rotating light. shadow_vec would do the same, but without breaking shadows in rotated lights if not used. Add inverse light transformation to shadow vec, so it's not affected when rotating lights; Added usage define for shadow vec. For shadow vec working properly when rotating a light, it's needed to multiply it by light_matrix normalized. Added usage define in order to don't do that if shadow_vec not used.

2019-03-12GLES2: Fix comments in previous commit that broke rendering (!)Rémi Verschelde
Do NOT use "[vertex]" in a comment... Kids, don't try to learn OpenGL on a production branch right before a stable release.
2019-03-11GLES2: Add comments around EXT_shader_texture_lod checkRémi Verschelde
To avoid reintroducing bugs as I did in #26928 and #26932. texture2DLodEXT and textureCubeLodEXT are only for the fragment shader with https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_shader_texture_lod.txt In the vertex shader, texture2DLod and textureCubeLod are built-in.
2019-03-11Revert "GLES2: Ensure extension checks for texture2DLod"Rémi Verschelde

These can't be done after any non-preprocessor token.
2019-03-11GLES2: Ensure extension checks for texture2DLodRémi Verschelde
In canvas.glsl and scene.glsl, we were using texel2DFetch from stdlib.glsl, which uses texture2DLod. In both cases, the stdlib.glsl include came before the define of texture2DLod. Might fix issues for drivers that don't support GL_EXT_shader_texture_lod.

2018-12-21GLES2: Define 'lowp' for OpenGL 2.1Rémi Verschelde
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.

2018-08-27Style: Enable clang-format on GLSL shadersRémi Verschelde
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.

2018-08-20Revert "Batch GLES2 draw calls"Marcin Zawiejski
This reverts commit f55039b194bbbd8d797b667d67e5677fb429d356. 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.
2018-08-14Batch GLES2 draw callsMarcin Zawiejski
Adds GLES2 draw calls batching for the same render list item that uses multiple rasterizer commands (e.g. Label node; a node with multiple GDScript draw_* calls).

2017-01-14Style: Fix whole-line commented codeRémi Verschelde
They do not play well with clang-format which aligns the `//` part with the rest of the code block, thus producing badly indented commented code.

2016-09-07Rename misleading definePedro J. Estébanez
The macro USE_LIGHT_SHADOW_COLOR actually was being defined when the shader used SHADOW (the output shadow color), not the shadow color set for the light so it's better named USE_OUTPUT_SHADOW_COLOR. In 3D there's not that difference but renaming as well for consistency.
