Detailed Description

ShaderVertexAttribute describes the attributes that shader program will read when executed by graphics device.

Shader vertex attributes have assigned location. Graphics devices have a limited number of locations (For example, OpenGL ES 2 has 8 attribute locations available, and OpenGL ES 3 has 16). Within a shader program, each attribute must be assigned to unique location.

Shader vertex attributes also have element type, rows and columns. These indicate what kind of data shader program is reading, and how many elements. The mesh vertex data may be stored in different format in memory. Together with mesh vertex attribute data type and shader vertex attribute element type, the graphics device sets up any necessary conversions.
