Specifying graphics pipeline creation parameters

Creating a graphics pipeline requires us to prepare many parameters controlling its many different aspects. All these parameters are grouped into a variable of type VkGraphicsPipelineCreateInfo which needs to be properly initialized before we can use it to create a pipeline.

How to do it...

1. Create a variable of a bitfield type VkPipelineCreateFlags named additional_options through which provide additional pipeline creation options:
   • Disable optimization: specifies that the created pipeline won't be optimized, but the creation process may be faster
   • Allow derivatives: specifies that other pipelines may be created from it
   • Derivative: specifies that this pipeline will be created based on another, already created pipeline
2. Create a variable of type std::vector<VkPipelineShaderStageCreateInfo> named shader_stage_create_infos. For each shader stage enabled in a given pipeline, add a new element to the shader_stage_create_infos vector, specifying the...
