Opengl es 2.0 shader 3d object tutorial android

Here’s what the model looks like in Blender and Maya: Meet your new model! Based on the Arwing from Star Fox for SNES, I’m pleased to introduce starship. Your New Model: The Star (Fox) of the Show This time you won’t be accessing or modifying your directory as much, but it doesn’t hurt to be neat and tidy. You can find similar files for your cube model from Part 2 in /cube/. starship_decal.png is a texture for your model that you’ll use later on. Inside /starship/ you’ll find starship.obj and starship.mtl, which were exported from Blender and then processed by blender2opengles (from Part 2) to create starship.h and starship.c.

They both contain all of your models’ files required by OpenGL ES and a few extras.

/Resources/: This folder contains two subfolders: /cube/ and /starship/.

Again, you won’t have to open it in this tutorial, but it’s there if you want to explore or modify it-if you have Autodesk Maya, of course. The model was built in Maya and then exported to Blender, so this is the original copy.

/Maya/: This folder contains the Maya scene for your new model ( starship.mb).

Your command line tool is gone since you completed it in Part 2 and won’t be needing it here. The project also has an extra class called Shader that you’ll use later on. The iOS app is the same as GLBlender2 from Part 2, but with a different model (and additional resources).

/Code/: Here you’ll find the Xcode project for your iOS app ( GLBlender3).

You won’t have to open it in this tutorial, but it’s there if you want to explore or modify it.

/Blender/: This folder contains the Blender scene for your new model ( starship.blend).

The contents are a bit different from those in Parts 1 and 2:

Here’s a quick overview of each component-you can find more information in their dedicated tutorial sections later on. The Return Of The King, The Dark Knight Rises, The Last Crusade… all great trilogy conclusions, but none like this one: GLBlender3! Getting Startedįirst, download the starter pack for this tutorial. Part 3: You are here! Get ready to implement a simple lighting model for your 3D scene by writing your own OpenGL ES shaders! A shader is a dedicated program that instructs a graphics processor how to render a scene.Part 2: In the second part, you learned all about the MTL material definition and file format, which allowed you to add Blender materials to your model.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.
