How To Draw An Image From A 2D Array In Modern Opengl


This section covers only part of the OpenGL 1.1 texture API. We will see more of textures in later chapters. Note that an image that is used as a texture should.

We don't need any perspective applied to the coordinates since the game is entirely in 2D so an orthographic projection matrix would suit the rendering quite.

Rendering an actual sprite shouldn't be too complicated. We create a textured quad that we can transform with a model matrix after which we project it using. Creating a collection of mipmapped textures for each texture image is cumbersome to do manually but luckily OpenGL is able to do all the work for us with a.

Although I haven't mentioned it there are initializers for 2D arrays. For example this statement creates the 3by4 array that is shown in the picture below:
