GLECS

A collection of classes and methods I developped to make my life easier when using OpenGL

Conventions

Just to make my life easier and so that I don't need to look everywhere to find them, here is a small list of conventions I use:

camelCase for functions
snake_case for variables and namespaces
PascalCase for classes

Most classes will be found in the nbop::glecs namespace.

Shaders

By default, the following uniforms will be automatically set:

• u_model: the model matrix
• u_view: the view matrix
• u_projection: the projection matrix

TODO :

• u_time: the time in seconds since the program started
• u_delta_time: the time in seconds since the last frame
• u_resolution: the resolution of the window

And the vertex data cn be accessed with the following attributes:

• v_position: the vertex position
• v_color: the vertex color

Concessions

Since it will mostly used with OpenGL, I will use glm structures and functions to represent vectors, matrices, etc, instead of implementing them myself.

Misc

Some informations I ALWAYS ask myself and I don't want to forget:

With glm matrices being in column-major order, in C = B * A, A is "applied first", then B.

TODO / IDEAS

A way to require Components when creating a Component. For example, a Renderer requires a Mesh and a Transform.

Check encapsulation for example with the Shader class.

Limits the access level on a lot of methods. Right now, anyone can just bind a Mesh for example.
