3D for iPhone Apps with Blender and SIO2: Your Guide to by Tony Mullen

By Tony Mullen

In case you have ever attempted to put in writing a video game with simply simple openGL ES then you definately comprehend that is not how you can advance a full-fledged iPhone 3D video game. the trail specified by this booklet is how one can move.

The publication begins with an easy advent to OpenGL ES to demonstrate my aspect above. bankruptcy 2 is an advent to SIO2 programming. bankruptcy three and four discover the Blender global and combine the scene created in Blender into iPhone SDK through SIO2. via bankruptcy four, we've got the "World" spinning at the iPhone machine, in 3D (a depraved twist at the vintage "Hello international" software, enjoyed it). you furthermore may get a pleasant pat at the again from the writer for making it thus far! The bankruptcy on 'Picking and textual content' is great. the remainder of the chapters does a pleasant activity of winding up the creation to all components of a 3D game.

There are a few mistakes too within the e-book - specifically in bankruptcy three - the place we decide on the sting loop - the best way defined in bankruptcy didn't paintings for me, yet relating the Appendix on Blender helped. it's also really easy to wander away in all of the intricacies of Blender and C/C++, yet with slightly of exploring it is simple to come again on course - patience can pay off. I want the writer had additional an Appendix on complicated C/C++ for the positive factors utilized in the publication.

Sample text

If you don’t have any experience with OpenGL or graphics programming, then now would be a good time to read through Appendix B, which is an overview of some key concepts that will help you better understand what’s going on in the code. Setting up the SIO2 environment to work within the iPhone SDK framework and to make use of all the necessary tools is not trivial. Fortunately, you don’t have to. As you saw in Chapter 1, in addition to a wide array of in-depth, heavily annotated example projects, the freely downloadable SIO2 package comes with a ready-made Xcode template project for you to begin work with right away.

The Target system in Xcode enables multiple related applications to be created within a single project, which is useful in large-scale development projects such as client-server applications. For iPhone development, however, it is unlikely you will ever need to deal with more than one target per project, so this functionality can be mostly ignored.
