OpenGL Object Wrapper

OpenGL Object Wrapper

The OpenGL Object Wrapper implements RAII style resource management for OpenGL resources.

Implemented Wrappers

Glow provides wrappers for the following OpenGL objects:

• Texture
• Shader
• Vertex Buffer
• Frame Buffer

Rendering Infrastucture

Glow provides the Pipeline class that implements a multi stage rendering algorithm. Specify the render passes with add_pass, add geometry, lights and set the camera matrices and execute.

To facilitate state the Parameters provide the means to associate uniform variables to values without a specific shader.

Dependencies

The glow library is built on top of C++17 and builds on top of The OpenGL Extention Wrangler Library and OpenGL Mathematics.

Building

The primary development of glow is done with Visual Studio 2022. Dependencies are pulled with vcpkg, folow the Get started with vcpkg guide to setup your build environment.

CMake is available, but mostly serves are vcpkg integration.

License

The glow libary is provided under the MIT license, see LICENSE.txt for details.

glow's Issues

CI

At least check if the software builds.

Release glow.

• Update Change Log
• Check Versions
• Tag & Release

Replace custom build debug infrastructure with standard means.

Extract License.txt

This is needed for vcpkg and generally a good idea.

Improve README

• add missing types
• go into more detail on phylosphy

Make consistent and improve API doc.

CI: CMake Check Script

Write a script that checks if all headers and sources are contained in the CMake file.

Integrate Into vcpkg

Sync With Private Repo

Port to Linux & Mac

• CMake build
• ifdef the windows bits (trace / show_message_box_with_callstack)
• CI build with targets

Changelog

Add SHADOW pass

As a graphics programmer, I want a pipeline render pass that renders each light with the camera at the light source so that a light mask can be rendered.
