Name: Joseph Projects below. You can share my projects with anyone ^^. My projects are mostly free to use, only several projects that i will define are like games, or AI ready projects that are not open-source, but the code is there for anyone to read, so a half open-source. - but it will be only several projects that are ready, that are more invested in using the application not modifying.

Projects:

Version: 1.0.0-1.0.3 (next versions upcoming, check the list) will start from version v1.0.0; all versions are open-source, free use. very easy to understand and implement!

v1.0.0 v1.0.1 - fixed missing parts. very easy too to understand and implement!

Screenshots of the OpenGL2.1 program V.1.0.4: this is still V.1.0.4, later versions upcoming.

Note: don't worry, because there shouldn't be missing files. even if there is, its only 3D models loaded into the renderer which is blocked by the Github because too large size;

the following code can be moified.

 Model cubeModel, barrelModel;
 cubeModel.position = (Vec3D){0.0f, 0.0f, 0.0f};

 cubeModel.vertices = cubeVertices; 
 cubeModel.colors = cubeColors;

 cubeModel.name = 'C';
 
barrelModel.position = (Vec3D){5.0f, 0.0f, 0.0f};
