Without further ado, it’s time to implement some materials! Getting Startedįirst, download the starter pack for this second part of the series. Part 3: In the final part, you’ll implement a simple lighting model for your 3D scene by writing your own OpenGL ES shaders!.colors, textures, and lighting properties that you can assign to a portion of a model) to your cube. Part 2: You are here! Get ready to learn about the MTL material definition and file format, which you’ll use to add Blender materials (i.e.You also created a simple iOS OpenGL ES app that displayed your model. Part 1: In the first part, you learned all about the OBJ geometry definition and file format, and used this new knowledge to create a command line tool to parse a simple Blender cube into suitable arrays for OpenGL ES.
Welcome back to the three-part tutorial series that teaches you how to make an awesome 3D model viewer for iOS by exporting your Blender models to OpenGL ES!
