When creating a new sphere mesh with high number of slices/rings the top and bottom parts of the generated sphere are removed. This happens because the triangles in those parts, due to high resolution, end up being very small and are removed as part of the 'par_shapes' library's optimization. Adding par_shapes_set_epsilon_degenerate_sphere(0.0); before generating the sphere mesh sets the threshold for removal of small triangles is removed and the sphere is returned to raylib correctly.

@MikiZX1 I'm afraid I'm not merging this change. The shaders are placed in glsl100 directory, that leads to confusion and it defines custom implementations that are not really required if working on OpenGL ES 3.x, raylib should already support them for that backend, no custom functions should be required. |

Example - deferred rendering updated to work for both Desktop and Web (using GLES3).
This one example will require custom compile command:
emcc -o shaders/shaders_deferred_render.html shaders/shaders_deferred_render.c -Wall -std=c99 -D_DEFAULT_SOURCE -Wno-missing-braces -Wunused-result -O3 -I. -I../src -I../src/external -L. -L../src -L../src -sTOTAL_MEMORY=134217728 -sFORCE_FILESYSTEM=1 -sEXPORTED_RUNTIME_METHODS=ccall -sMINIFY_HTML=0 -sUSE_GLFW=3 -sFULL_ES3=1 -sASYNCIFY --shell-file ../src/shell.html ../src/libraylib.web.a -DPLATFORM_WEB --preload-file ./shaders/resources/shaders/glsl100/gbuffer.vs@resources/shaders/glsl100/gbuffer.vs --preload-file ./shaders/resources/shaders/glsl100/gbuffer.fs@resources/shaders/glsl100/gbuffer.fs --preload-file ./shaders/resources/shaders/glsl100/deferred_shading.vs@resources/shaders/glsl100/deferred_shading.vs --preload-file ./shaders/resources/shaders/glsl100/deferred_shading.fs@resources/shaders/glsl100/deferred_shading.fs
For this example to work on the Web, raylib for web will need to be built with these commands:
emcc -c rcore.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rshapes.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rtextures.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rtext.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c rmodels.c -Os -Wall -DPLATFORM_WEB -DGRAPHICS_API_OPENGL_ES3
emcc -c utils.c -Os -Wall -DPLATFORM_WEB
emcc -c raudio.c -Os -Wall -DPLATFORM_WEB
emar rcs libraylib.web.a rcore.o rshapes.o rtextures.o rtext.o rmodels.o utils.o raudio.o
