[de32fda] | 4 | -I should store multiple buffers (e.g. vertex and index buffers) in the same VkBuffer and use offsets into it
|
---|
| 5 | -For specifying a separate transform for each model, I can specify a descriptorCount > ` in the ubo layout binding
|
---|
| 6 | -Name class instance variables that are pointers (and possibly other pointer variables as well) like pVarName
