Implementation: 3D Mesh

Overview 

In this post we shall deep dive and understand implementing a mesh.

Details

IGeometryMesh

This defines the abstract class that every 3D mesh object must override. It defines methods for generating vertices for the 3D object and populating VBO and EBO buffers of the GPU.  

Methods

Name	Description
GenerateVerticesData	Populates vertex data buffer based on the input. parameter att contains bitwise Ored type of vertex data. e.g, POS|CLR parameter vaoutl stores generated data in the corresponding buffer.

IGeometryMeshIndexed

This structure defines the abstract class that every 3D object must override. This interface is derived from IGeometryMesh class. It defines methods for generating vertices for the 3D object and populating VBO and EBO buffers of VAOUtil object.

Methods

Name	Description
GenerateIndicesData	Populates index data buffer. Index data buffer contains locations number of the vertices.
GenerateVerticesDataIndexed	Populates vertex data buffer based on the input. parameter att contains bitwise Ored type of vertex data. e.g, POS|CLR parameter vaoutl stores generated data in the corresponding buffer.
