Recep Aslantas	6626d2b74f	Update affine.h	2020-11-22 01:25:34 +03:00
Recep Aslantas	5bda762df6	use epsilon to compare results in glm_uniscaled()	2020-11-22 01:14:18 +03:00
Recep Aslantas	f9824a8dc6	test: use custom epsilon to compare	2020-11-22 00:59:48 +03:00
Recep Aslantas	ccd3058adc	remove CGLM_USE_DEFAULT_EPSILON * to override float epsilon we just need to define GLM_FLT_EPSILON * CGLM_USE_DEFAULT_EPSILON was redundant, also it forces to override system default epsilon which may not be good idea, because not all systems may support smaller epsilon values	2020-11-22 00:38:57 +03:00
