Found some issues when building for web using latest emscripten 1.38.30, traced the error and found that eglGetProcAdress does not return function pointers for VAO functionality, supported by extension.
It requires more investigation but now it works (avoiding VAO usage)
Issue was related to vertex tangent attibutes not uploaded to GPU, a quick solution was implemented for new vertex attributes loading for already existing meshes... I don't like it specially but it will work for now.
No examples built for the Web platform functioned properly due to lack
of resources in the virtual file system provided by emscripten.
This patch addresses this problem by adding
'--preload-file local_path/resources@resources' emcc option to link
flags whenever necessary.
The default memory limit for emscripten applications is 16 mergabytes,
which might be to little for some examples, especially given that the
resources are also included in that limit.
Normally, using this option disables some asm.js optimizations, but
there's no such cost for WebAssembly.
Planning to promote raudio module as a simple and easy-to-use front-end for the amazing mini_al library, so the name change.
Name comes from raylib-audio but in spanish it also remembers to word "raudo", meaning "very fast", an analogy that fits perfectly to the usefulness and performance of the library!
Consequently, raylib version has been bumped to 2.4-dev.
Added a bunch of useful text management functions.
Consequently, some already available functions like `FormatText()` and `SubText()` has been renamed for consistency. Created temporal fallbacks for old names.
raylib version bumped to 2.3.
Changed parameters order for consistency with LoadFontData() and other functions when an array is passed by parameter and array size is the following parameter.
This commit implements a big update of rlgl module, intended to optimize some parts. This change could break some code bases... hopefully not, but it could.
The BIG changes to the module are:
- Replaced LINES-TRIANGLES-QUADS buffers by a single one, now all vertex data is accumulated on a single buffer and managed with registered draw calls. LINES-TRIANGLES-QUADS could be used the same way as before, rlgl will manage them carefully. That's a big improvement of the system.
- Support multi-buffering if required. Just define MAX_BATCH_BUFFERING desired size (currently set to 1 batch). Should be enough for most of the situations.
- Removed temporal accumulative buffers for matrix transformations, now transformations are directly applied to vertex when on rlVertex3f()
- Reviewed rlPushMatrix()/rlPopMatrix() to be consistent with OpenGL 1.1, probably I should remove that ancient behaviour but... well, it was not consistent and now it is.
- Minor tweaks: LoadText(), I broke it in last update... also multiple comments reviewed.
- TODO: MAX_BATCH_ELEMENTS checking should probably be reviewed... done some tests and it works but...
raylib resource data file for Windows platform (containing raylib icon and metadata for executable file) has been renamed to a more consistent name: raylib.rc.data
Also required to work with tcc compiler.
Now `BeginTextureMode()` does not clean buffers automatically, that behaviour has been changed because there could be some case (i.e. painting software) where texture buffer does not ned to be cleared; user is responsible of clearing buffers using `ClearBackground()`
Useful for bitmaps pixelated fonts where anti-aliasing is not desired!
Change also enables additional font generation mechanisms in a future (cleartype, hinting...).
With the recent CMake cleanup, getting raylib's dependencies for use
when building rlgl_standalone is quite straight forward, so lets enable
it again.
Fixes#508, just properly this time. :)
Remove that link_libraries_to_executable() hack and defines a proper
raylib target that can be used with target_link_libraries.
The same target is also available for external (user) code by using
find_package(raylib).
This results in:
- Remove hardcoded build directories from examples and games CMakeLists.txt
- Allow rlgl_standalone and other special examples to be built easily
- Allow CMake projects to find_package(raylib instead of fiddling with pkg-config
- Makes code a little more maintainable
- Fixes#471, #606.
- Makes code less confusing by removing the double use of PLATFORM (#584).
Note that this is still not _The Right Way_(TM), because normally
raylib-config.cmake (or its includes) would be automatically generated.
I didn't manage to get that to work though, so I went the easier route
of just wrapping pkg_check_modules for consumption by find_package.
1. Always synthesize a complete frame of audio, using a second buffer (this prevents gaps in playback)
2. Sine is computed correctly, with an adjustable frequency
3. User can modulate frequency in real-time with mouse
4. Entire audio buffer data is shown, visually demonstrating how sine changes in wavelength
Examples can be compiled for web with no code change at all! Usually
examples need to be refactored for web... using emscripten code
interpreter (emterpreter), it can manage synchronous while() loops
internally... as a downside, execution is very slow...
This change allows rlgl.h usage as independent single-file header-only module... still some tweaks required, like removing GLAD dependency... required extensions could be manually loaded!
Also removed shader_distortion.h, embedded in rlgl.h
Currently, if:
* GCC doesn't supports -no-pie: Build error
* GCC supports -no-pie
* GCC is not configured with --enable-default-pie: No-op
* GCC is configured with --enable-default-pie:
Slightly worse performance because we still generate -fpie code
(-pie affects linker, -fpie affects compiler)
So instead of probing for existence of -fno-pie -no-pie, remove it altogether.
Fixes#540: Build breakage on Debian 8 with gcc 4.9.
- Added Vector3OrthoNormalize() to raymath.h - not sure if it is correct
- Implemented MeshBinormals() - Mesh struct has not a place for them...
- Updated model_material_pbr example - tested but not working on my GPU
(old Intel HD), actually, it never worked on it...
