Opengl中正式支持UBO是在Opengl3.1的版本,在这版本之前需要确定是否有可支持的扩展(扩展名为 ARB_Uniform_Buffer_Object),比如GLEW库中可以通过判断GLEW_ARB_uniform_buffer_object是否为true,true则支持,false为不支持: if(GLEW_ARB_uniform_buffer_object){printf("GLEW_ARB_uniform_buffer_object = YES\n");}el...

Consider increasing rendering/limits/global_shader_variables/buffer_size in the Project Settings. Maximum items supported by this hardware is: " + itos(uint32_t(Config::get_singleton()->max_uniform_buffer_size) / sizeof(GlobalShaderUniforms::Value)) + ".")); ...
The max. allowed alignment (as per spec) is 256 bytes which may be much higher than the data size we actually need for each entry (one 4x4 matrix = 64 bytes). Now that we know the actual alignment required we can create our host memory for the dynamic uniform buffer: size_t bufferS...
