- Fixed D3D11 eating 40000000 cycles for no reason (Thank you Bill Gates) - Refactor drawing to keep blocks persistent in memory - Make string usage easier & more consisten (macros for string vs const char*) - rdtsc intrinsic (get cycle count) - Profiling macros (generates a google trace json) - Write D3D11 debug messages to stdout - String_Builder & thorough tests for it 2024-07-02 15:27:33 +02:00			`int entry(int argc, char **argv) {`

- Text rendering - Font loading - Measuring for formatting & justification - Utf8 Glyph walking - Commented example in oogabooga/examples/text_rendering.c - Small 2D renderer refactor - Pass 8-bit integers "type" and "sampler_index" to shader - Sample texture differently depending on "type" (text or regular quad) - Sample with nearest/linear min/mag depending on sampler_index - Set min/mag filtering in Draw_Quad - Images are now created and deleted directly with gfx calls rather than deferring it for gfx_update. - We can now set image sub data with gfx_set_image_data() - Images are no longer hard coded to 4 channels - Utf8 utility: - utf8_to_utf32(): convert utf8 bytes to a single u32 codepoint - next_utf8(): Convert first utf8 character in a string to a u32 codepoint and advance the passed string to the next unicode - Renamed m4_multiply -> m4_mul for consistency - Refactored os window to be DPI aware (scaled_width vs pixel_width) - in minimal example, renamed hammer_xform -> rect_xform 2024-07-07 20:27:34 +02:00			`window.scaled_width = 1280; // We need to set the scaled size if we want to handle system scaling (DPI)`

v0.00.004 - Custom logging, more concurrency & bugfixing Concurrency: - Refactored spinlock out of OS api (deprecated old procs) - Concurrency utilites: void spinlock_init(Spinlock l); void spinlock_acquire_or_wait(Spinlock l); bool spinlock_acquire_or_wait_timeout(Spinlock* l, f64 timeout_seconds); void spinlock_release(Spinlock* l); void mutex_init(Mutex m); void mutex_destroy(Mutex m); void mutex_acquire_or_wait(Mutex m); void mutex_release(Mutex m); void binary_semaphore_init(Binary_Semaphore sem, bool initial_state); void binary_semaphore_destroy(Binary_Semaphore sem); void binary_semaphore_wait(Binary_Semaphore sem); void binary_semaphore_signal(Binary_Semaphore sem); Macro MEMORY_BARRIER - Concurrency tests Docs: - custom_logger.c example to show how one can make a custom logger and have logs displayed in-game Utility: - draw_text_and_measure() which is just an overload of draw_text but it also does a measure and returns it Misc: - Added u64 thread_id to global context. This is set in main() for main thread and in thread startup when you dispatch a Thread - Fixed a bug where plain rects would be drawn with the incorrect color - Fixed a bug where quads from earlier frames would be drawn 2024-07-09 18:36:37 +02:00			`draw_rect_xform(rect_xform, v2(.5f, .5f), COLOR_GREEN);`
