Unity3D: Creating a GUI with both 3D and 2D elements
Posted by Dimitri | Filed under Programming
This post explains how to create a GUI on the Unity3D game engine that has both 2D and 3D elements in it. Some may say that is just a matter of setting up a new camera with a dedicated culling mask just to render the 3D elements on the GUI. While this is partially true, adding a 2D image using a script with GUI function calls will cause the 3D image to be covered by the 2D image. That’s why this post will focus on how to set a GUI that has a 3D element with a 2D background.
As usual, at the end of the post, a Unity3D project is available for download with everything that was explained here.
Android: Creating a button to load images from a remote server
Posted by Dimitri | Filed under Programming
This is a follow up to the post published two days ago that explained how to load images into a View’s Canvas from different sources. Differently from the last post, I will explain how to load images from a remote server after the View has been loaded and rendered on the screen. Also, this post features how to download an image after pressing a button.
So, let’s get to it. The first thing the reader might be thinking is that we just need to create a button and place the code that downloads the image inside it. It’s not as simple as that, due to these problems: (more…)
Android: loading images from a remote sever, SD card and from the Resources folder
Posted by Dimitri | Filed under Programming
As stated on the title, this post will explain how to load a image from 3 different sources: the SD card, from a remote server and from the Resources folder. Since the methods and code used to load these images from these sources are different from one another, this post is going to be divided into three different parts, one for each location.

Android OpenGL: Texture from Canvas
Posted by Dimitri | Filed under Programming
Another post about Android programming, although this time, it’s going to incorporate some OpenGL techniques. The code below shows how to draw a Canvas into a Bitmap, and then, load it as a OpenGL texture object. This means that it is possible to use all Canvas methods to draw into a texture, like drawCircle(), drawPoints() or drawText(). This is useful to render text to a texture and to dynamically generate textures.
So here’s the code: (more…)
