v0.7.7: 2D Affine Transforms Update

on GitHub

New Features:

2D Affine Transforms

Now we have 2D Affine Transform functions. 2D Transform functions are suffixed with 2d, functions that don't have any suffixes are 3D. For instance glm_translate2d() is 2D and glm_translate() is 3D.

New Functions:

Translate2D:

• glm_translate2d()
• glm_translate2d_to()
• glm_translate2d_x()
• glm_translate2d_y()
• glm_translate2d_make()

Scale2D:

• glm_scale2d_to()
• glm_scale2d_make()
• glm_scale2d()
• glm_scale2d_uni()

Rotate2D:

• glm_rotate2d_make()
• glm_rotate2d()
• glm_rotate2d_to()

All these functions are documented at https://cglm.readthedocs.io/en/latest/affine2d.html . Rotate functions are rotating around Z axes. SIMD optimizations will be applied in the future releases.

Bugfixes and Improvements:

• mat3_mulv: function behaviour to match with mat4 ( thanks to @terri00 )
• mat2: don't use vec4 directly on mat2 because of alignment requirements may be different
• define CGLM_DEFINE_PRINTS macro for test targets to see printed results
• documentation fixes

Build:

• build: update CFLAGS (-O3 -std=gnu11) for check/test target to match the main target
• build: remove RTC1 from CMake build for Windows/MSVC
