shader-programming

This repo will handle just enough code to create basic shape on which shaders will be apply.

Design

class Vertex {
 +glm::vec3 Position
 +glm::vec3 Normal
 +glm::vec2 TexCoords
}

class Texture {
 +unsigned int id
 +string type
}

class Mesh {
 +vector<Vertex> vertices
 +vector<unsigned int> indices
 +vector<Texture> textures
 -unsigned int VAO
 -unsigned int VBO
 -unsigned int EBO
}
